Board: /diy/
"/diy/ - Do It Yourself" is 4chan's imageboard for DIY/do it yourself projects, home improvement, and makers.
Welcome to /diy/, a place to:
Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.
Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Efficient use of space edition Posted a week or two ago about getting some broken snap rings out, finally found the time to fuck with it again. One side popped right out with a pick, other side refuses to come out at best it just spins in the groove. Any ideas? We got one step closer to getting back off the grid. 2500 watts of glass on the roof. inverter/controller is installed. shed is wired.
next weekend we plan to trench, run 00 conduit to and from shed/house main panel and install/run weatherhead DC wires PV to controller.
once we get all the heavy work in next weekend, I can finish the rest by myself. connecting it all at the controller and wiring in the batteries.
system is still due for an upgrade, but we're going to use what we have for now. once we save up (cash only buyers) we will purchase 18 345w panels and a 300AH LiFePO4 battery to replace our FLA units. I'm not talking about used cars. I mean for metal, machinery, etc.
I see so many Euro videos where they're like:
>Just head down to the scrap yard to find one
Nigga, I don't have that. None of the metal recycling places will sell me material. I just want to get some cheap metal parts and old machinery, but they won't sell it to me. Post your hammers and argue about who makes the best hammer itt. I just cleaned my Vaughan 19oz Cali framer up. What's stopping a guy from ripping apart an old refrigerator and making an air conditioner from it?

There is no defined starting point, grab a book and start reading or buy an arduino off ebay/amazon and start messing around. There are a plethora of examples online to get started.

So why are internet contracts necessary? You can tune into radio for free so how come there's no antenna device that pulls free internet from the air in a similar manner? Is it worth picking up one of these to paint a relatively small area of fence (around 70 feet)?
Is it any more or less likely to bleed through to the neighbours than brushing? Is that a realistic issue that I need to worry about?
I have gaps between the bottoms of panels and the ground, concrete and brick in areas too, so would need to cut in around those, but I am planting in front of all of those areas anyway. Post what you've acquired recently and why little paypiggies I decided to under cut my fireplace to install laminate flooring. It turned out okay all things considered. And why do (((they))) insist on calling it hydrochloric acid ? HVAC is for faggot.
all you need is a 2 holes on the wall, dust filter, and 2 fans (optional) Does anyone else feel intense amounts of rage when watching one of these DIY shows as much as me?
I'm a pretty laidback guy, but these shows make me want to assault women and fags. I am tired, I don't want to deal with hunting shit anymore. I just want to input money and receive stuff without it being a knife fight over some old junk worn out machine that'd been out of production for 70 years and I have to get raped to get replacement part on ebay by some other boomer.
Are chink mini lathes viable to get running well without needing another lathe or a mill to fix the brand new machine you just bought? I just want to make small steel items, maybe up to an inch in diameter but realistically 5/16 or smaller diameter machine screws. I want to implement an error detecting and correcting system to keep my data perpetually.
I would need it to work through the deaths of individual drive, and I should be able to varry the amount of redundancy
It would also be great to know where there is already error correction in my data
Do y'all know any good resources, programs, etc?
Thanks Where do you buy tposts?
Is this actually how much they cost? I would have expected about half that Every farmer needs a real hoe.
Sure, there's plenty of mass production brands out there at the stores.
Those work OK if you're dainty with them.
But does anyone know where one can get heirloom quality hoes?
Hoes that can take a real man working the dirt with them >acquired a decent set of quality tools by now

What else can I do besides working on my bicycle, disassembling kitchen appliances for scrap metal and do the odd car fix on the fucking street because I don't have a garage either?
I can't move so I considered buying a small plot land and build a shack there but then I will get my tools stolen by a crackhead if I move it there, won't I? Degreelet here and no I am not going to post in the SQTDLGBTQ because fuck jannies and I'm not gay.
I want to chop this tree down. My plan is to rent a chainsaw and start with cutting the limbs down away from the house at the top and work my way down.
Is this an actual a good approach? It's not particularly high but at it's highest it's definitely a long 25ft thin branch that exceeds my roof line. im starting out making things out of beads, i got really thin fishingline as beading thread cuz other beading string is way to thick to fit through the small seed beads but the thread is so strong that when using the small beads it just makes the project go out of shape and bunch up (as seen with the lizard picture). I cant make anything small with it Is there any way to make your own A/C unit for a small room? I don't want to blow hundreds of dollars on one of these only to have it break after the warranty Yo guys - my central A/C just shit itself. Not blowing cold air & the indoor line is freezing up. Capacitor looks good & condensing unit fan runs fine, but that's about as far as my knowledge goes. Any ideas what to check next?
Also why the fuck do I have to wait 5 minutes before starting a thread?? This captcha system sucks. I live in a rural area and i won 300 dollars worth of lumber in a poker game.
I wanna build a shed,where i can store my winter tires,shovels and think about where my life went wrong.
I don't want to spend really that much more,so i was thinking instead of the regular frame and 2x4 design i would build something like a woodstore (pic related),just cover it tightly from all sides . make it 14x10 so i have space to lay down and cry.
Would i be able to do this without the middle beam, i want it at least 6.5ft where the roof is at its lowest so i can stand up inside,and i want to cover the walls with OBS and watch it rot away in a year or two. So do ya'll think would i be able to this,or would the roof just fucking cave in on me?
Or Is there a cheaper solution,that won't kill me as ssoon as i step foot inside? I want to make a cyclone dust separator adapter like webm related but I'm a cheap fuck and I want to make it even cheaper. How would you hook up two hoses to a bucket like that? I don't want to go overkill so I'm thinking that just two 90 degree or 45 degree PVC fittings would do just fine. But I don't know how to fix them to a bucket properly. 
How do I buy chemicals? I'm in Japan but these idiots are so uptight about everything it's damn near impossible. I've gotten most solvents I could reasonably need (barring tuolene) but nitric, hydrochloric, and sulfuric acid are all just straight up fucking banned. Best you can get without a permit is 10% of HCl/H2SO4 and 5% nitric acid. Like, it's insane. Yeah I could buy TEN LITERS and fractionally distill over a month (and probably kill myself in the process because retard fingers and earthquakes) but it would cost a stupid amount and take forever.
What companies ship to JP?? Even fucking chemsavers won't ship int, and most eurofag suppliers won't ship to JP.
What's worse is that even when they do ship, customs is basically guaranteed to fuck me over. The only places I've found domestic that sell anything at all are Matsuba on Amazon and Jikken-kun (hayashi chemical corp on monotaro won't sell to individuals). WTF do I do?
I really wanna get my hands on some thiourea but I can't find anyone who sells it. Is there anything cheaper an or better than the hackrf? Do they literally just blow warm air over the food?
some of them cost over £500. I already have metal boxes and hot wind isn't exactly hard to attain. Hello. I would like to find quality hair clippers to cut my hair off with.
I have bought this set a couple of years ago for a great discount, is this hair clipper a good model which should last me years?
The hair clipper is a Wahl 09243-2616 and doesn't use a battery I want to build my own DIY computer from scratch, but I don't really know where to start. The main purpose of it is to learn more about computers and how it all works down there. I'm confident with logic gates, boolean algebra, not so with prototyping. I watched Ben Eater's videos about his project, as well as some other videos to similar topic. What books/other materials will be helpful? What is the starting point for such project should be? Is it better to pick up something like 65c02 and build around it or made everything by myself? Disclaimer: i’m not planning to do anything of this. I don’t suggest trying any of this stuff without proper guidance ,knowledge and preventive measures.
Main questions:
is it possible to make a safe, small scale reactor capable of providing energy for a medium class home? How much would be it’s price ?
How much knowledge would be needed to handle such a device? Would a housewife be able to handle it with newly developed technologies?
And if an accident happened:
How large would be the area of effect? Why spend tens of thousands of dollars on campers when you could just build something like this out of free coroplast?

Why are quill stems and underappreciated diy item? They can be used to build all sorts of things yet nobody ever talks about this Trade Jobs Are DYING OUT...

https://www.npr.org/sections/ed/2018/04/25/605092520/high-paying-trade-jobs-sit-empty-while-high-school-grads-line-up-for-university My retarded boomer Dad cut down a bunch of tree branches (red circles in the picture below) and now you can see straight through into our backyard. These trees are 20 years old. I don't know why he did this. My Mom is very sad that he did this, she is crying.
Mother's day is coming up and I want to be a good son. What can I build or do or plant to try and help fill this space back in and have it look nice? >be journeyman union member.
>get paid prevailing wage to do relatively little work for the wage.
>single, no kids
>can easily pay all of my bills on unemployment insurance
>mfw I work as much or as little I want all year round
>will retire with a pension
>have healthcare as long as I am paying dues, doesn’t matter if im currently employed or not. lucky me I think I developed swimmers ear or something after a trip to the ocean. the ear pain sucks enough but it's also putting pressure on my jaw hinge making it literally impossible to sleep. to top it off I have to catch a plane in the morning so 0 chance to go to the doctor for proper treatment.
is there anything I can do to effectively mitigate for the pain and swelling besides tylenol or am I just fucked until I can make it to a clinic? Hey yall, I've been thinking of starting a commercial vent hood cleaning business with a couple buddies being that we all have restaurant experience. I'm already thinking of chemical costs and basic shit like scrapers/ an LLC, any suggestions or tips about anything I'm not considering?
General diy business thread if nothing else noticed the sewing thread was gone and i wish to discuss it So housing is too expensive as it is and I've been feeling ambitious as of late. So more and more I've been interested in taking a task like this. I have the know how and I have family that have built homes before that have taught me the ropes as well as would be willing to help, but I'm not sure about having the time at least right now, so it's more of a future project. People are saying 5000 sq ft would cost anywhere between 400k to 1 mil, so 10,000 sq ft they would estimate as more. 10467 sq ft total living space, fireplace, and basement are in the plans. Planning to build on the west coast, Anchorage Alaska, or in a few options in Russia. Foundations are the most expensive thing to build, so I could take care of that to cover labor costs. Does anybody have estimates for this being viable below 1 mil? Or would you say this is pointless dreaming? My own yard always looks like shit because I won’t use chemicals.
I can draw or design something beautiful but I can’t make it happen because of weeds. Is it possible not to use chemicals? Or is the secret the pros have lots of chemicals and really powerful?
Like I read a lot about an entire organize method of overcrowding your plants so weeds have no space to grow and a tough fight for nutrients. It’s been 3 years, my plants are all mature, and there are fucking weeds everywhere. I just spent an hour, filled two 5 gallon buckets with weeds and it looks like my garden hasn’t even been touched.
I’d be embarrassed to charge anyone for these results. I am autistic to explain formatting.
i produce way too many eggs.
i live rurally
I plan on building a self serve farm stand at the end of my road for eggs.
I can't, for the life of me, come up with any decent concepts that would protect it from the weather, but also prevent it from getting 110+ degrees inside the storage area and causing incubation.
i live in appalachia basically for climate context.
it can get about 100 degrees in the sun here and -10 in the winter.
heat consideration is more important than cold cause people don't moving and I can't do shit about them freezing beyond moving indoors.
i raise chickens and ducks. I had guneas but they were assholes so I ate them.
my wife breeds ornamental birds and we are trying to making a decent free range batam who is predator sensitive, but that's a side note.
I'll attach pictures of birds. I bought some of these tinpot "damascus" blanks for some knives, but they ended up being laughable I would never cut packages with, so I want to make some Beskar. Will acid etching work with fake damascus? It's just pressed chinesium with oxidation I think.
https://youtu.be/4tYMUqsVhfc can i replace a 320x240 54 pin lcd with a 640x480 54 pin lcd ? Farm Fresh Scotch Eggs.
simple, portable, no need to heat for eat. I want to give my room the hotel aesthetic. How would I go about doing this? How horrible would it be to live under somebody running 4 of these 24/7? I'm trying to imagine what life is like for my neighbor right now.

>>2774581 I got 7 cubic yards of soil for my raised beds
Shoveling it is killing me
Is there like a way I could vacuum transfer it? I have an old shop vac and a leaf blower/sucker combo thing. I was thinking maybe if I just don't put the shop vac base on, or the leaf bag, one of those might work to like spray it into the bed. Or maybe that will just destroy them.
Is there something like that? I'd buy one. Otherwise I could rent a loader but I'd also have to get it delivered and picked up, that gets kind of pricey. 
I wanna make a fly-weight enclosed multi-purp trailer, but still keep it foldable, and thus easy to store, with semi-removable structure, based on Harbor Freight.
But I want it bigger than 4x8, and to keep it fold-able pretty much limits plywood floor to 5/8", if that, more like 1/2".
Plan to make it about 6'6" wide, with extra steel frames under main frame about same as tongue frame to support the 1'3" over-hangs, and so the wheels would be sorta enclosed (but seems like could still be got to, maybe with a socket). I'd probably add extra steel with self tappers, then when its all figured out and plywood and test folded, etc, take it a welder to glue up everything, including the "factory" framing for extra strength.
Also might extend the back about 1' or little more, because WTF not. Maybe make a big full size rear door also a loading ramp, but it looks like the whole trailer could tip when Tongue Pins are pulled, but probably lot nicer to load with ramp into otherwise level trailer. Going for maybe 6'4" standing headroom, so Ramp would be 6'4".
Might have vertical rear 'streamlined' clam-shell doors AFTER the rear main-hatch/ramp, that would swing forward and attach to sides of trailer when parked and open, mostly for light high bulk storage like sleeping bags and hanging clothes.
Might have a mode where rear-ramp can be supported from its rear-hatch frame by chain and serve as Patio, or have rear ramp horizontal and swing clam-shell storage space over it, for one big internal space.
Not sure about the front, but semi-streamlined starting at front main-frame steel, maybe with small side door. What would be the cheapest way to accurately cut this shape out of a 3mm (11 gauge) piece of steel, without access to expensive machinist tools? So all I have to do to get a job is to go to a construction site and ask for it, despite having barely any experience whatsoever? Who do I ask to speak with? I am moving up north soon where everything is 3x as expensive. My new house has a large garage though, and I'd like to have a workshop. I just don't know what I should buy before I go to save money. I want to collect as many different screwdriver bits as possible to spite anti-right-to-repair manufacturers
Is there anyone doing good compilation work? A private collection, a museum?
I've only found standards for hex drivers yet
Pic related what can these be used for? could i use two of these to shear things reliably or do they fail if misused like that? 1. Can I put up drywall on this box or does the bottom need more support than the 4 corners?
79in long (6.6ft), 24in wide (2 ft)
2. Do I need support for the drywall all the way to the edge to the wall where the railing is coming out of
(14.5in long gap) I replaced the old chapa of my front door with a new chapa that I had for a long time. the old one when you locked it it wouldn't lock unless you turned the knob a bunch of times so the new chapa is a big quality of life improvement because it locks how you want it to. the chapa won't get in place to lock unless you lift the door. either the door is too low and I have to readjust the door or the hole where the chapas stick goes is too high. what should I do? How do I disassemble this drain in my shower?
I want to take, I assume, the inner ring out, which is I assume, screws into outer ring. I am a rentoid and have no tools beyond Leatherman at this time, but plan to buy some tomorrow). Applying rotation to triangle plastic just bends it to the point of snapping. The goal is to pull the hair out.
Do I buy pliers and just open them up to meet with inner rings inner edge? I feel it it won't do shit beyond scratch it.
Who the fuck came up with this retarded design? how worried should i bee with this anodized garden hose connection being connected to brass, and why the aluminum work like an anode? A place for anything to do with Welding.
Post your welds, ask questions and discuss sticking metals together.
IDK I just want a place to talk about welding. >Do you even melt, bro?
I did my first casting today, I'm totally a foundryman now. My first two melts earlier in the week I made some ingots, just melting soda cans. >>2783890
Yesterday I made my first flask from a spare fencepost, and some greensand from sifted playsand and a mix of sodium bentonite and calcium bentonite. Yard marking calcium carbonate as parting powder, worked great. Designed a little ashtray in Fusion360 and turned it into a pattern. I did a pretty bad job but I was impatient and really wanted everything ready to do this casting today. Rammed up fine, might've been a little dry, but just barely. Worked out okay though, very happy with the result after a brief cleanup.
Do you scrap? Stack? Do you sell signs on Etsy? Do you sand cast? Investment casting? Do you like huffing zinc fumes and snorting silica powder? Show me your furnace, show me your castings.
Sand and jpeg compression don't get along. For the last couple years, I've been keeping one of these with gas in it in my garage, like it's no big deal.
I'm starting to get the idea (Googling and skimming through some of the links) that's a really fucking retarded move, and I'm having trouble coming to terms with that.
I'm hoping people here can convince, me it's not that stupid or it's not even bad so I don't feel like a total fucking jackass with these mistakes like I do all the time. Hey smart and strong fellas. Didn’t see a plumbing thread. I have an issue where my shower head rod (plastic) snapped off in my supply pipe in the wall. I understand this is actually fairly common and got some internal pipe wrench extractors but I’m in a bind. The smallest will kinda catch but not grab and turn at all, and the medium 1/2 just barely won’t fit past the plastic stuck in it at its lowest profile. Any advice on how to get it past without damaging? Thought about heading up the tool but that seems last resort Gonna need one soon for drivetrain work. Which ones have you got, and what would you recommend? There's some Craftsman and Kobalt ones at my nearby Lowes but I'd like a bit more input. should I just keep buying red wings? might try some georgia boots or some thorogoods for the first time.
press f to show respect Is there anyway how to get Solidworks for free? Solid Edge has free license for hobbyists but I would like Solidworks since its more popular.
I dont want to pirate it unless its only option. The design for this thing is so compelling, but most of it is a gaming thing. What features would you have built into it for doing real things with it while having your hands free?
Things I can think of (besides radio, mp3, clock, messaging, etc):
- Network monitoring: ping when some device just signed in to the home wifi (people are back home)
- Scanning for wifi fransmitters (bugs)
- tracking GPS
- mesh network this smug bald son of a bitch I'm not an engineer, I just like to make stuff. Naturally, lots of the content I watch often happens to be made by engineers (or engineering students), and seeing them go about making things sometimes makes me wanna kms. You've got a team of 5 dudes making a rc car, each bro i would assume assigned with his own task, trying to calculate every single thing that could possibly be calculated around said rc car before they ever dare to assemble the real thing. Listen I get why the methodology exist and I'm grateful for it, I don't want our buildings or bridges or commercial airliners to be eye balled, but following this workflow whilst trying to create something new is grating to watch. What happened to trying shit out? That's what the OGs did in the early 1900s and it looks a lot more fun than how we're going about it today. What would be the best method of supplying wired internet to multiple buildings over say 10 acres of land spread out?
Not necessarily the cheapest nor the highest bandwidth, just running wire to different spots that are going to go through one isp bill? No classes or anything. Just youtube videos and gear I can buy locally >>https://archive.org/details/lawnmower_202001/page/n5/mode/2up?view=theater
greetings,
i bought a second hand mower and its giving me somewhat trouble.
First of all, it never ran right since i bought it a few weeks back.
filter and plug were replaced. I had to change the throttle as the plastic one broke and since it never ran right it obviously needs a carb readjustment.
The manual says adjust throttle cable (green circle) until the screw (missing, red circle) touches the casting. Since the screw is gone i have no fucking idea what the factory setting here is for the governor tension.
Step two would be to lean the engine (screw orange circle) until the revs drop and then turn back half a turn, but if i lean the engine with full throttle it will rev way past 4000 rpm an i know this is not safe to do
How the fuck do i readjust this? what is the proper order here? Also, how does this thing choke itself when cool?
The engine is a 185cc 3hp L head I have unlimited sand where I live. I want to make it into Silicon for fun, and maybe if I’m retarded enough I will become a silicon mogul and oust Taiwan. What do I do if I want to purify silica from sand and turn silica in to silicon?
I imagine I could use a panning method with water and a rotating pan maybe? Then add crushed charcoal and put it in a furnace to make CO2 and Si? Dewalt Toughsystem 2.0 + Milwaukee Packout + All other custom modifications you've made, seen or purchased. >still trying to make something out of my land
Feels comfy bros I am something of a clothes and linens horse. I dream of owning a place where I can at least have a cloest but right now almost everything is in my room. I have looked at plastic vaccum bags but learned this is bad for the clothes since it can make them smell. Lately I came up with an idea that I wanted to share and also sanity check here. I was wondering what a metal case could do with a racheting system and realized what if I don't need to build such a complicated system that could buckle. What if I just take some thin plywood and use some thin ratchet straps. what kind of compression could I expect to get out of this? would it work better or as good as vacuum sealing? Even including the thickness of the wood needed? I could also try to get metal or glass but that would increase the weight and cost. what does diy think? >We're going to test that! Do pumps create flow or do they create pressure? So I was wondering how difficult this dream deck/"treehouse" would be to DIY? My property is next to a steep canyon and I always wanted to place an access deck around the oak tree in my backyard. It's 80+ years old so I'm terrified of permanently killing it. The slope is not vertical but nearly, and the actual tree is a lot smaller than the image.
I calculated the cost and it will be roughly 20-30k in materials. If I can even find a professional who would bother to do this I'd expect it to cost 100k+
So my question is based off the concept image, is this feasible to attempt DIY? Or am I being way too optimistic? What can I do with these? I want to do some stuff and I need a rotary hand tool. Some stuff includes maybe hitting a PC case and some wood.
what do I get? >owner decides to build an additional wall in office

How fucked am I? I know this is an incredibly dumb question, but I’m trying to figure out the actual name of this wooden barrier placed on the outside of new construction so I can figure out how best to remove it. This is placed on the exterior of my new home’s backdoor and, now that I’m adding some stairs to the yard, I’m trying to figure out how best to remove it without annihilating my trim. Sadly, ‘wooden barricade exterior new construction’ isn’t the most targeted search term on Youtube.
Thanks for any help! how I stopped that nigger from stealing my wrench. Can I make my own tire slime for a slow leak on my bicycle tire? A old boomer neighbour said they used condensed milk in the old days. Would corn starch and water work? Is it gay as a man to order sewing kits online so I can repair my socks DIY style? All the darning tutorials I see online are made by women. Does anyone know of a fair priced powerstation that can run one of those portable tent A/C units or a swamp cooler? It's got to be expandable and last at least 7 hours. I'd like to DIY a whole solar powerstation rig at some point... it's just... what fucking powerstation do I get I want to get an electrician or HVAC apprenticeship, but I can't take a pre trade course. What are some ways I can teach myself so that I can show I have some idea of what I'm doing? I broke of these pic related stoneware mugs and am thinking of doing a faux kintsugi thing. However, I also want to be able to microwave this thing, so JB Weld is out, epoxies are apparently out (temperature issues and potential fuming or whatever when exposed to enough heat), and superglue was never practical to begin with.
Unless someone has any better ideas, I was thinking of resorting to a cement mixture of some kind and sorta painting on my gold (mica) pigment onto the cracks and then figure out how lacquers work. What's the most autistic trade/skillset and why is it Robotics/Industrial automation? How to I strip the paint off an old, heavy duty steel PC case? and any tips for repainting it
I have a belt sander, a detail sander and an angle grinder but I legit don't know where to start how do i make my room better?
also male living space thread >holds the world together Birthday was a week ago. Went ahead and got a new pair of boots out of the attic that I've been hoarding for a while. Got tired of my socks getting soaked every time I got in water up to the sole of my boot. Probably still wear the old ones when I'm not irrigating and it's dry, or at the shop to get a bit more wear out of them... Fringy things on the new boots were cut off on day 1.
Any tips to keep the soles from cracking around where the leather stitches to them? That seems to be the placed where water intrusion starts. Should I put a fat bead of urethane windshield adhesive on my old ones and see if I can waterproof em again?
Also workboot thread. Post em up. I'm interested in learning mechanics and shit and working on cars. I've heard working on lawnmower engines is a good place to start. But I really don't know what I'm doing.
What am I supposed to do, take an old lawnmower off the side of the road and fiddle around with it until I've pulled it apart? Then what?
I'm guessing I'd want to try and fix broken ones. Anyway as I say I've got no idea what I'm doing and no idea where to start. Is there some guide out there that can hold my hand and tell me what to do? What needs to be done to mouse proof old places like this with lots of random little holes?
Thinking of buying the place in rural Australia.
There's mouse droppings around... I bought curtain holders and a portable bidet
Screw Nails, Threaded Nails, whatever you call these, how do these work?
I don't know which the guy gave me for which, rod holder needs to be drilled into regular concrete and cement wall and the bidet holder needs to be drilled into tiles
I imagine nailing them into tiles would result in cracks? so it's for the walls >permanently lubricates any metal or plastic
>lower friction dry than oil on uncoated metal
>improves any oil or grease used with it as it wears
>used by NASA on space shit
>industry standard coating procedure is just sandblast the part then blast the WS2 on at 120psi
Is there anything special about media blasting with half micron particles or will a $100 blasting cabinet do it well enough? I haven't been able to find much about doing this at home, let alone on a poorfag budget. If it's as simple as it sounds, you should be able to coat every moving piece of metal you own for a few hundred bucks. It'd be an excellent application for household stuff like locks, hinges, and tools, and even better for lawnmower, motorcycle, car, etc. engines.
Is there something I'm missing here or is this one of the most based materials ever? >mineral materials such as sand, gravel, and crushed stone are extracted from BLM administered public lands are used for ready-mixed concrete, asphalt, and many other building materials.
>There is no specific application form for requesting removal of mineral materials from public lands. Persons interested in buying mineral materials should contact the local BLM Field Office
Low lease rates (like $165 for 20 acres) makes it almost free to collect ... is this too good to be true? What would you do to your house if money was no object? >that guy who has a 5 figure wera/knipex/pb swiss/etc. tool collection in pristine collection, who has obviously never used them and is mechanically de-inclined as if raised by a single mother I want to do stuff like pic related, clearly starting with something smaller and work my way up, have some space, have not too much money but I have time.
I don't know anything about stone, how do I start? Just buy a hammer and chisel and carve away? 
The previous owner of this house apparently either did not know shit or hired people who did not know shit to do shit in his house.

It's that last one that got my panties in a real bunch.
Then like the good white folk they were they boxed it all in with drywall and fucked off for a couple of decades before having the cast-iron American Standard tub spray finished and then selling their shit-dripping, wall-weeping, 10-inch-fucking-stub-outs-sticking-out-of-the-wall mess off to me instead of investing the money in fixing it.
The tiling floor/walls was fair and held up until the rusty heads on the drywall screws started to pop tiles in the shower around the tub.
Pic related is my phase 1 ghetto repair. Measured at the studs I went from 5/8" at the worst part of the dip to 3/16", a 1/2" dip is under 1/8", and 1/4" gaps are all gone now. I can now sheathe my floor in peace knowing that I have in some small way helped make the world a better place.
Thank you for reading my blog post. You can now return to your regularly scheduled fapping. I want to make acoustic guitars for fun. What tools do I need to start out, what fundamental skills do I need to learn first, and what are some good resources for learning? I'm buying a new tractor, it gets delivered next week. Kioti CX2510 with the FEL, 3" spacers, weighted rear fill and a 5 spine box blade. pretty excited, can finally fix my gravel driveway I want to make a hexpod "ball" project similar to this https://www.youtube.com/watch?v=8yO-H22eNNg
The one which has 6 legs, move about, but then wraps itself into a ball and starts rolling by taking legs out.
However, on the vid related I find the asymmetry of the thing (bottom half are full 18 servos, while top only 6) very irritating.
However, making it symmetrical (18 servos bottom 18 top, 36 total) seems stupid too since top parts are not likely to be used for walking.
Also, I want to place a camera somewhere. Any ideas? S&G 6730 Internals Edition

The plan is to buy a few cheap ceramic/porcelain pendants, broke them and repair them using cheap chinkshit sets from amazon
Has anyone tried it? Is it possible to do something decent with it? Hi /diy
With a fella at my astronomy club, we're interested in the making of a binoscope.
(pic related: it's 2 telescope side by side)
There seem to be awesome realizations on the internet, but close to no diagram or advice.
This is a 3 stage project:
1- we'd like to try it out with 2 newtonian telescope (skywatcher 200/1000) since we have the same model.
2- make a small frame that would use these mirrors (2x200) since we're not experienced in the telescope making business
3- scale it up to 2x300 or 350mm.
My biggest concern is finding good secondary mirrors, since they'll need to be bigger because lower on the light path.
Any diyer experienced in the field? The Gojo Shlomo fears the Dawn and sand Chad My first DIY project this year. I only had access to a hacksaw with hammer and nails do get this done so it took a while but it was pretty therapeutic to do. I still need to sand and coat but am wondering how much one of these would be at retail price. It’s 200cm by 150cm btw. Why cant it be at ground level? What's the weird crap above my curtains? What are the best /diy/ jobs? Is harbour freight like princess auto? I'm working on a personal project that isn't a normal repair or assembly, and I need to go to the store and ask for help. What I need to know before I go to the store is what is the difference between a pipe and a duct and a hose. I have social anziety so I have to be prepared with a little speech that will work in the store. If I ask wrong and he just stares at me I really start to fall apart.
Pic relates is not the part I need btw. 
ACK-SHUALLY it's *designing* edition
>What is this and why would I care?
Field Programmable Gate Arrays (FPGA) are how poor-fags (<7f plebs) can design a complex IC and test it out QUICKLY at home.
You could design a fairly complicated IC for a small project and use the FPGA as an ASIC-lite (with a flash-storage PCB) or to use your design to get an actual IC etched yourself or in a group-funded chip print. (Like https://tinytapeout.com/)
The basic process is: HDL -> Yosys -> nextpnr -> FASM.
You can also use vendor software from Xilinx etc, but it is very locked down. I would argue it's more convoluted as well.

Ideally I want something that can do carpet and floor maybe the car .. a lot of the floor ones say they can do area rugs so does that mean they can.do carpet too?
Companty thst starts with bis and ends with sel seems to own the market on these but idk if theyre any good they seem kind of too cheap to be true
I dont know how to make this post seem less like spam I've been training tae kwon do for some time and I saw that there is a necessity of recreating some sort of detection on the armor. To give more context, in the major competitions, there are sensors in the armor that are responsible for detecting contact and the amount of force applied. I'm wondering if I can replicate it with an arduino and want tips on this.
What I've found so far is that it is possible to use FSR sensors, but they are not good for measuring a scale of force. So I should be able to use load cells with an Arduino and a HX711 amplifier module.
Any tips on doing this whole project? Hardest part for me might be inserting it all inside the armor. these are the dumbest mfers, just gaping at you. fuck off, there is nothing to see. So I've been replacing all my outdoor frost freeze spigots and I've come to my hot/cold and need some ideas/advice
They are connected to pex that goes underground and runs to my outdoor kitchen. I'd like to redo this in a way that doesn't look so fucking rigged.
Ideally I'd like an outdoor mixing faucet or something, lines going to the outdoor kitchen that can be turned off for freeze (like it is currently) but in a way where I don't have to unhook everything switch between using it as a spigot and feeding the outdoor kitchen.
Any ideas/products that would accomplish this would be greatly appreciated. Preferably without an insane amount of renovations

Go away Anyone have good experiences buying a small lot (4-10 units) of 18650 batteries from a vendor on Amazon or Ebay?
From what I gather, they are all sketchy as hell. Even the ones with good reviews seem suspect. The brands don't matter because they place if full of knockoffs (100% real authentic Samsung!)
tl;dr where do I buy batteries? 
My parents have an older house they bought recently that was added onto over the years by prior owners who weren't the most professional. Some hacky stuff was discovered, but up till now the hot water heater had worked fine.
Hot water goes out so they call a contractor, he finds the lower heating element is heavily corroded and says its time for a new tank, parents agree. A few things about the old tank and power setup: It went 2x30Amp circuit breaker -15 feet-> emergency shutoff (see pic) -> tank. While the old tank wasnt heating water it did have voltage running to it. I ran my non contact electrical tester over it and got the beeps. I barely know how to use a multimeter but I managed to find 120/240v on the upper/lower elements. So it had power but wasnt pulling amps.
About the attached pic: No idea what caused it but clearly that black wire on the right overheated and cooked off the insulation. After cutting back the wiring to where good insulation was and attempting to reinstall it I noticed the threads that screw need to go into were stripped or fucked in some way. Re-using that box without replacing the body there is asking for another overheating scenario.
Fast forward and the new tank is installed but it too has voltage but wont pull amps and heat water. I disconnected from that emergency shutoff box and direct wired to the new heater. Still not pulling amps. The breaker hasnt tripped all this time. It's clearly letting voltage through.
I dont know what I need to test here or how to best do it. I have basic hand tools and a multimeter, even if I don't know how to use it to its fullest. Help me /diy/ I dont want my parents to be without hot water over the weekend + however long it takes to find a decent electrician in TN. But like what is this yellow discolouration on the ceiling? Mould?
Coldish climate I want a geodesic dome addition on my house. I want size picrel. I know this is masochism.
Question is how would you go about this? I was thinking metal frame with premade adapters at the corners to properly angle the whole thing. Pair that with premade triangle panels in wood frame with glass installed. I think this glass part is where the money will end up. How much will it cost to have this ceiling replaced? Hate mould I want to construct a similar design (an "invisible" chair that makes you look like you sit in the air) and I need the name for that part. It's a thing that would link two metal bars together, allow them to fold, but stop at a 90 degrees angle. How would you call that part? Do you know where I could find it? for leatherwork, you need a very dense material to tool (draw) and stamp on. We all have little granite slabs. I make luggage and messenger bags almost exclusively so that little slab is just top small. 2x3x8 slabs of granite are reterdedly expensive.
here are a few factors I'm considering.
1, my house doesn't have a concrete foundation so reverberation will just always be an issue. I want to get as much force transferred onto what I'm working on as possible.
2, I have read that a work bench the size I'm going to make will weigh 100s of lbs.
3, even the best concrete tables eventually Crack, sometimes within a year.
what are your thoughts What is this?
Seen in a house I inspected today in rural NSW Hello, I'd like to build something to keep my voice very low and allow me to train silently (or with less noise at least), do you have ideas/encountered stuff like this already ? Ideas of materials ? I was planning on using pillows and blanket, any idea ? Hello /diy/ quick question: why not put your meat birds in a cone upside down and decapitate them with like a cigar cutter mechanism? Why bleed the animal out while it's brain is attached and it panic when I could depart it's brain from body and bleed it's body anyway? Heck I could fill a bucket with warm water and clove oil and toothache herb to Chuck the head in so it doesn't feel the passing seconds of residual brain signal.
Unrelated garden picture. Do you like the way it looks?
Do you like the names of the different countries?
Suggestions and criticisms are welcome. Should I use polyester or cotton thread for darning my socks? I hate the phillips screw
these black little shits always break, bend, destroy and spoil Is there any reason I cannot do this to save some space in my small apartment? An anon recommended a temporary solution to a cheap sprinkler system with a $5 timer but I can't find it edition.
I'm thinking of getting like 5 hoses for all my trees too
Anon other tips?
