Board: /diy/

"/diy/ - Do It Yourself" is 4chan's imageboard for DIY/do it yourself projects, home improvement, and makers.

Makers gonna make!
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.

Stupid Questions That Don't Deserve Their Own Thread Thread

What do i do about mice? I have a pretty bad problem they die completely in winter but now i already catch them sometimes and they fucking shit all over my kitchen its so fucking gross.

I just don’t know if theres any way i can find every entry point they come in and I’m afraid of finding a bunch of piles of shit all over trying to find it. I am so fucking paranoid of the hantavirus shit.

So far what i wanna do is lay out traps, keep my kitchen totally clean, use bleach spray to clean all the surfaces so the smell keeps them away, use scents that repel mice. I have cats but its still not realy doing much and hes barely in the kitchen. He goes there to eat and then runs off. Plus feeding the cats sometimes i get food around the kitchen floor so even more mice.

What the fuck do i do? I dont think finding every single space they can get in will do anything they can fit in any hole literaly like 3/4 of an inch and i live in a really old really big house with a shitty basement.

I cant keep living like this non stop last summer i found rat shit and they shit all over my stove and counter and everything and its so fucking gross. If i keep my kitchen totally clean like wash every single dish every night will that stop them from coming into the kitchen? And move to cat food upstairs for a couple weeks or something and be really careful not to get food anywhere else just so they stop getting the idea of coming into the kitchen? I’m paranoid that just like single bread crumbs will keep them coming in and i have no idea what to do.

How much is it to hire someone? On google it says 100-200 dollars that sounds pretty cheap. I just dont know if i can find every single entry point in such a big house.

I guess if i can just cut back on how many are coming in and lay out traps more and keep everything clean ill stop seeing shit everywhere right? I’m so fucking paranoid of the hantavirus

>What printer should I buy? [Last updated 1-1-2200]

Under 500 USD: Creality CR-1000, Anycubic Chiron, or Qidi X-One2000
Under 1000 USD: Prusa i3 (Mk9 or Mk8)
Over 1000 USD: lulzbot is probably dead
SLA: Anycubic Photon, Prusa SL1, Formlabs Form 3
Buyer beware: some chinkshit clones are too good. :)
Instead of buying a new printer, you could consider building your own:

>Where can I get free things to print?
That will be $5.

>What CAD software should I use?
Solidworks, Inventor, AutoCAD etc. all work, but Blender and Fusion 360 are free for most users, that doesn't include (you).
Variants of Solidworks, Inventor and AutoCAD may be free depending on your profession, level of piracy and definition of ''free''.

Ave /diy/.
I recently bought a house and in the living room is an old weatherwall aircon unit. I want to remove it so i can mount my tv on the wall without it being off center.
I'm wondering what my order of operations will be. I will get my brother in law to disconnect it as he is a sparky, but im not sure how I will go about sourcing some vinyl cladding to patch the huge hole on the exterior, as well as actually patching the hole itself considering its an eastern facing wall and I obviously need to ensure its completely protected from the weather. Have any of you tried something similar to this before? Any advice?

Oven repair
I need to change the bake element in my oven. From everything Ive read Im supposed to cut the power to the oven. But my circuit breaker isnt shutting off power. I was talking to a guy at home depot and he said as long as I dont turn the oven on I should be fine.
Im not sure what to do. Not worth dying but I dont want to call an electrician just to take out two screws if its not needed.

Gentlemen, is it time?
COVID-19 is going strong and hospitals around the world are experiencing shortages of equipment. Many have tried to invent cheaper alternatives for ventilators but they are lacking.

I believe it is our turn. Let us show the world what we can do. Our combined knowledge and whims of boredom can bare fruits of labor of the likes no one has seen. Many times has 4chan been made out to be disgusting and evil. Shall we harvest salt by doing what others can not?

Hey I have a thread already but it's long as fuck and I don't expect anyone to read through the whole thing before my trip to the hardware store tomorrow so can anyone crash course me on why the FUCK my shop teacher 6+ years ago gave me a wood stain that made my hands smell like chemicals for like the whole fucking six years I had it? I don't want the project I'm making to do that to anyone who picks it up off my shelf. Any other info on wood stain would be appreciated if you're bored/have the time.

Also I've been on this site 9 years and am not an inconsiderate pos so I checked before I killed a thread and hopefully you all can support me putting this shit into the ground.

I'm quarantined and will probably legitimately want to kill myself soon (I refuse to actually do it until I have some experiences I need to have but it doesn't mean the urge isn't there). I've done around 150 mostly digital projects since August of 2017 (I have a folder for the projects file for each, ~150 folders, >>>/po/579259 has some of them) so I'll definitely end up doing this. I've been on this site 8 years and mained /b/ for about 6 of them. I unironically want a fingerbox. Yes it's a useless meme, but I love the idea of having a subtle joke like that to see if my friends recognize and to put on my shelf of items that have a story attached to them.

Since it's such a small amount of material, I'm figuring I can get away with few tools. I'm still deciding on details but I already know I'm going to line the inside with (probably fake) fur so people can actually play with it. Going to line hole edges with tiny ball bearings. I'm probably going to go to the the hardware store and get pretty cheap shit wood (not like it needs much structural integrity) and just sand and stain it unless you guys think it's worth doing something better. Will definitely end up making designs on the outside; going to carve a stamp to give it a fake manufacturing company logo and either burn or carve probably swirls on the outside.

I'm debating between choosing some kind of nice looking screws or nails for the joints to give it an industrial look and between carving out some things to make nice looking joints (like pic related).

Interested to get literally any input from you guys, and I'll post as I make it, so here are some things I'm interested in input on:
-Joints you consider personal favorites
-If wood type really matters much or if a nice stain will just make it look fine
-Can a soldering iron do fine for burning in designs? I have one.

That's all I really have for now but expect an actual progress thread unless coronachan keeps me from getting supplies halfway through.

Portable Dishwasher Leak
I just bought this place a few months ago and I have found that the dishwasher is now leaking. It appears that it is a slow leak as only a small puddle forms. It happens towards the back left corner if you're facing it. How can I safely identify the leak without destroying the machine? It doesn't seem possible to get the metal shell off without at least the back plastic holding piece. Should I replace this 20 year old thing with something new? If so, should I go with something portable or should I add hook-up for a permanent dishwasher?

Noise insulation
I live in a condo and my room is one thin concrete foam wall away from the shitter and the doors are hollow cardboard stuff too. The problem is that I can hear people pissing, shitting and farting and that is getting annoying. I'm also a shallow sleeper and somebody going to kitchen at night is also bothering me.

So what I need is to soundproof a wall and a door without taking up too much space or money. I'm not building a sound lab quiet room, all I need is not to hear the turds hitting the bowl. I would prefer to keep the current door for now because I don't want to have one odd door and can't afford to change all the doors now.

My current plan is:
1 glue the sand-filled polymer membrane to the wall. It's thin but heavy and claims to absorb 20db
2 slap a 20mm cork sheet on top of that as finish, it both absorbs noise and looks decent. I think having a cork finish wall is gonna look good enough and I mostly care about my comfort.
3 do the same to the back of my door, plus add the sweep and gaskets to it.

Is this a sound plan? Will this actually decrease the noise significantly?

House Re-Stumping
Im about to sign a contract to purchase my first home. Its in an area with high rain fall and the area has a hight amount of sate/ rock in the soil. The area originally used 'billy pine stumps' (cant remember if thats the actual name the real estate agent said) but most of the stumps have rotted and the house is mainly sitting on stacks of bricks. I can go get som ed photos today if someone can help me diagnose if it is worth buying or not. It looks like its pretty bad, but i dont have many options because all the houses in this price range are in simular condition, but atleast this is on flat ground and not on a steep hill like others.

How do I lower this cement tank?
I have a 2000 gallon cement tank that I want to bury below the frost line (6 feet). I got it for nothing last spring with free delivery. Its decent and usable.
I have a few 20 foot sticks of 6 inch schd. 80 pipe and a welder. So far all I've come up with is fabricate a frame and buy some chain falls to lower it down where it is. I don't really want to dig below this thing that probably weighs more than 15,000 pounds. I tried moving it with my diesel tractor and 3 ton truck at the same time but she wouldn't budge. Maybe I could dig an incline and use pulleys? I really don't want to hire any heavy equipment. I have a front end loader on my tractor to move the earth.
I want to use it to catch rain water from my roof, I'm off grid 40 miles away from the nearest service.

Should I care about making sure I have a good reference for my next job
Basically I'm a plumbers apprentice of 1.5 years. I did handyman work before and learned how to fix finish stuff and shower bodies and what not so I have a good amount of experience. I can work with everything except PVC and pex which isnt common in my city.
But my company is scummy. They wouldn't get me a seatbelt for 6 months, they stick me on shitty jobs all the time even though I want to learn and do real jobs. They pay me 18 bucks an hour when I could be getting 22 elsewhere as a Jr. plumber. And they keep me with a scummy plumber who's always high and has temper issues because I'm the only apprentice he likes.
I've responded by not coming in as much as i should. We all get 2 sick days and 5 vacation days, mechanics included, I've taken maybe 10 days off so far this year and they're mad at me for it. I took a lot of time off at the end of last year but my mom had gotten very sick and passed away so they didnt bother me about it.
Anyway, I just dont like my company anymore. I'm tired of working with the same dude for almost 2 years. I'm tired of working in an old shitty van with a bent frame. I'm tired of being stuck at 18 bucks an hour. I'm tired of being basically treated like shit by a bunch of rich guys that were born into the family business. WWYD? I've complained to my supervisor before but nothing has changed. Now they're mad I take days off but I hate my job and I've explained this to them and they agree with my points I bring up but nothing changes.
I have a good work ethic and get along with everyone and my supervisor tells me i have real potential, but i feel like they're taking advantage. Should i care about leaving on a good note or put in my 2 weeks once I find a better deal?

Disconnecting a Gas Appliance
What are the chances that the valve will leak if I shut it off to disconnect? Should I run the hood vent to get the gas out? It has worked in the past without issue.

Used some quarantine spare time to build a shitty little balcony garden so my wife can grow fresh herbs.

From the lattice, I'll hang fourteen 8" terracotta pots, in a 4-3-4-3 pattern.

In that base trough, I dunno. Didn't really do too much research. There'll be between 16 and 24 inches of open vertical space, what good kinds of tomatoes could grow in that? Anything plum-sized?

I'll be putting casters and a removable drip tray under the base box, so the whole thing can just be wheeled inside when it gets nasty out. That'd mean year-round harvesting, right, as long as I keep the plants warm and in sunlight?

Water in the basement
Hey /diy/

We have a very old house with a dirt floor basement and we decided to pour in a concrete slab.
We're digging about 1/2' - 1' deep to flatten the terrain but now we're encountering problems.
We never used to have water break in from underground but now we get a stream on every side of the room after a rainfall.
I don't think it will be a great idea to just put some gravel and concrete on top of it and call it a day.
How do I get water to not erode everything from underneath? Do I just lay perforated pipe under the concrete and route it into the drain pipe for the sink?

This class is fucking amazing, I really want to ace it. So I looked around and I found that it can be done using arcs, the “R” notation, I guess. But I looked around and you can't draw a full circle with the arc function.
According to

DIY a COVID-19 Ventilator just in case
covid19-ventilator 01
So I hear the US has less than 200k ventilators. in the case that you are in a rural area and cannot access a ventilator in the eventual event that manufacture cannot keep up with the sick. Do y'all have ideas for it to work? Schematics?
Suppose I have access to a air compressor and electronic parts and tools. what's the air pressure etc that humans can take?

Creating a mechanically delayed vector irl
I've got an idea that could make use of a mechanism that creates the same movement for two objects, but with a time delay. For the time being, this applies to spacial location and orientation. This could be solved with programmed robotic arms, but since it's just a prototype, budget and simplicity are of the essence.
My initial thought was that I could use a rotating disc. Place both objects at the same radius, orient them compared to the redial axis and start rotating the disc at a constant pace using a motor. Since they're both rotating at the same radius, their spacial positioning would be limited to the circumference, and since their angle to the radial axis is set, their orientation would be the same at any point. With a constant rotational velocity, their time delay should be a factor of the angle and the rotational speed, both constants per initial placement.
A friend suggested a linear movement. Place both objects on a plank along the movement axis, orient them compared to the axis, and move the plank at a constant pace. The rotation should be unchanged, and the movement would match since they're moving over the same line. It's a simpler solution with a simpler result (constants are boring for a time delayed function).
What other means can you think of that would produce a delayed function of position and orientation between two objects? Note that I'm neither a fountain of money nor a mechanical engineer. My friend does work at an electrical motors company, so I could use his resources to achieve a prototype.

Dungeon Furniture
So I want cages for a BDSM dungeon, but all the good metal ones cost 1000$ each minimum, which can fuck off, I really want them to be high quality but Im retarded, I don't want one that will just break if someone kicks it, or looks like it was commissioned by king ooga booga of zwongoland, what do?

I also want to make other pieces for the dungeon, but I can more justify spending 1000 bucks on a Lucifer's chair or something

Acrylic Paint, multi purpose/surface
acrylic paint
I'm looking for a high quality multipurpose acrylic paint. It will not be used for different kinds of craft works and not for canvas painting. The first things I will use it for is painting a bottle and to dye a cotton string and I will probably use it on wood too and maybe leather.

Can I do all that with one type of paint? I'm looking for something high quality with good and lasting colors. I will only use it occationally, so small bottles is better than big.

I have been looking at liquitex, but it is mostly for canvas painting and I read it's not that great painting. It's just too much info out there for a no-painter like me to navigate. Please help. I'm building a lamp

My window tinfoil finally fell down
I'm gonna make a new fresh tinfoil covering to keep the light out. My last one was just electrical tape to attach the seams, but I'd like to make a better one this time. My initial vision was a big slab of cardboard with the foil on one side that I could just hang in front of the window as needed, but I don't have any cardboard.

Any lightweight ideas to attach it all together and make it firm? it's a fuckhuge window with sliding parts on the bottom, so it might have to be done in two segments.

What's the best way of finishing this?
I'm in the proces of finishing my ceiling.
The beams you see are warped, so I had to leave a bigger margin when I cut my plates in order to get them in. But now I'm stuck with gaps.

I've got 12 beams at 5m at both sides that need finishing, which is 60m ( about 200 feet).

I want to get it as neat as possible but I know plastering is going to take me forever, So I wanted to now if I could take a shortcut and silicone the sides. the largest gap is 5mm or 0.2 feet.

Plastering is going to take me two times and two times of sanding down. So I'll end up having done the ceiling, including painting, 6 or 7 times.

And those gaps at the side look like a bitch, with no guarantee of not crackling. I really hope I can silicone it, or if there is another solution. Woodpaste is downright shit for stuff like this, I've tried it. Much obliged.

Adding Casters
Screen Shot 2020-04-01 at 10.36.41 PM
diy something i'm struggling with is adding casters to galvanized pipe table I built.

to be exact the casters would need to be added to a: 3/4 to 1/2 reducer or the option would be to remove the reducer and attach the casters to a 3/4 elbow.

The problem is other than finding a 1/2 or 3/4 expanding caster with threading, I don't know how else to attach it.

My build on my table comes from the photo attached.

pvc pipe as fence post

I need to construct a deer fence for the garden this year on a tight budget. I have ordered deer fencing that is 7' high and 100' in length.

Studs aren’t positioned where I need them
I’m using Rhino Racks to elevate my roof box off my garage floor. This mounting is preliminary, just needed it off the floor and half-assed it. I’d like the racks to be as high as possible (need some clearance for taking the box on and off) and centered between the protruding wall bit and garage track hanger. The way it’s mounted right now, the racks are bolted into the studs. If I move the whole setup another 11 inches or so to center it, I’ll have no studs to bolt into. I don’t think drywall anchors would work, this is way too heavy. I know mounting 2x4s to the studs, and then mounting my racks to them is an option, but don’t want this to stick out even further away from the wall. Perhaps a thin steel plate bolted to the studs, then mount the racks to the plate? Need ideas. Thanks /diy/

>Minimum of 3 years experience in maintenance support/equipment troubleshooting
>Strong PLC programming skills, preferably with Allen-Bradley/Rockwell products and software
How do I get that without losing my current job?

I'm a moron, and I don't know what to use to clean which material. I have already made some metals and tv remotes have color washed away from all the aclohol I'm using while i wipe them down. I know I can't use bleach on any fabric, but I can't use it on practically anything except tiles and ceramic. Plastic is everywhere, sometimes it seems like alcohol can be used on them, sometimes it seems like it's to strong.

How the hell do I clean my house, what do I use, how do I use them, what is safe to use on which material, and how do I not inhale bleach and aclohol vapors all day when I use them to clean?

Woke up this morning to Gov Cuomo saying he needs 30,000 ventilators for NY immediately.

Happened to have just read an article about some clever Italians engineers who modified a full face snorkel for CPAP use.

Was aware (because, retired military and I have maintained my situational awareness), that my local hospital has only three ventilators.

Decided nobody was going to be riding to our rescue. Made my plan, went to work.

Called an emergency room physician to confirm the need. Highly interest, within hours I have gone from texts with head of Emergency Medical Services to phone calls with the Hospital VP.

If NYC can't get the ventilators they need, tiny, tragically hip Taos (pop. 7,000) was not going to either. Found the cheapest, best full face snorkel mask for the job. US Diver's will have 50 drop shipped to me for delivery arrival late next week.

Doctors tell me we have between seven to ten days before our hospital starts reaching its expected apex Wuhan Flu/Covid-19 patient loads.

My problem? My Mechanical Engineer son Alex and I did some calculations, mainly he did. To print 50 "connectors," the bright yellow plastic bit above the mask Alessadro is wearing in the picture/article would take us 6.5 days of flawless non-stop 3D printing.

We have zero supplies; zero PLA plastic filament and not the FDM 3D printer we need.

What would be helpful on this DIY project would be a little help. I think the way to go is to posse prototype (someone on the Internet has the CAD file of this snorkel mask, and/or owns one of these; and they also possess the measuring skills to help us fabricate a prototype design to print, test and then produce these across the local community. I plan to reach to the local FDM 3D printer community via community radio PSA and social media posts.

My fear is trying to fabricate while people are in need. Thanks.

Attachment systems
I want to /diy/ a bag that attaches to a bike rack. I'm willing to modify and even to make a bike rack myself if a special design is needed. The objective is to make a bag that attaches quickly to the rack without wasting any time. So I would be doing both, the rack and the bag so I can design them to work together.

There are multiple bike racks and all kinds of different bags on the market but all of them share one fatal flaw: their attachment systems suck and are usually strap based, This is totally time inefficient and frustrating when you need to put or to take your bag quickly.

My solution to this problem is to produce a bag and rack that are designed around a superior attachment system.

Now, my questions is: what type of attachment system should I use to create this project? I don't know anything about attachment systems.

I have two ideas that may work:
-The bag has magnets on the bottom. The rack has magnets on itself. The attraction force should be sufficient enough to hold the bag in place.
-The bag has a rail on the bottom. The rack has a rail on itself. The user pairs the ends of the rails and slides the bag till it locks in place. (similar to the telescopic rail that drawers have).

So to keep a long story short, had some pipes burst last year. The room the pipes burst in - I hadn't been into for awhile. I just shut off the water, ran a dehumidifier and dried it out. Left it until just the other day. It's mold city, I guess the valve isn't operating properly and it had a slow drip from the hole I cut in the ceiling. I didn't get around to replacing the pipe due to being out of country - and no one in the house.

So I go into that room and I have pasta looking mold growing from the carpet and black colored mold on the drywall where the drips are. Some fuzzy mold in various places on the carpet throughout the room.

Long story short, am I best to just cut out the carpet and replace the drywall? Is there a way to remove the mold permanently without removing materials?
