/diy/ - Do-It-Yourself

I've recently started building some things out of welded mild steel square tube and aluminum profiles, using both square and miter joints. So far I've been getting by with a handheld bandsaw and angle grinder. But it takes an inordinate amount of time to get a decent fit-up - can't get a straight cut with the bandsaw and have to spend a long time grinding everything square, which then fucks with the dimensions of the part. Can't seem to get the angle grinder to cut the tube either, takes forever to grind through 30x30x2mm tube - and it seems like you have to burn through two cut-off wheels to get it done.

I've had some luck borrowing time on a stationary bandsaw and it seems like it would work, but that shit's quite expensive. Have also seen videos of people cutting up tubing with the angle grinder directly, dunno if my failure with it is an issue with the cut-off wheels I've got, the grinder itself or something about how I do it.

What's the "correct" way to do it - cut square tube into flat and miter joints? Am I supposed to invest in a stationary bandsaw? Perhaps a stationary circular saw with a metal cutting wheel? Does everyone just do it with the angle grinder? There are tons of tutorials on welding the tube together, and of course fitting up aluminum extrusion is like legos, but everyone skips over the actually hard part which is getting a nice fit-up without massive gaps that are a pain to weld

How can I create something equivalent to this at my home?

I made a new one.

My washer from the 90's failed and I dropped the timer (most expensive) while dissambling and figuring it out, causing it to break. Found another washer for free, works, better than nothing. But the amount of bullshit involved with it...
>No ability to set water level
>Put it on "deep water wash" but it still only fills half full
>Auto sensing
>Stops filling when you open the lid
>Won't spin at all with the lid open
What the fuck is this shit? I know how dirty it is, I know how much soap I put in, I know what I want. I set it to deep water wash, so fucking do it. Fill all the way goddamn it. It fills to half. Half. I said full, you stupid fuck. Occasionally end up filling it manually with a bucket.

Is this really how bad it's gotten? My old one had a dial. If you set it to full, it filled to full. Period. Very straightforward. You pull on the dial, it starts working. There was no start button. There was no auto sensing. It didn't do any of this shit. What the fuck is wrong with this world. I have no control over this thing and have to fight with it to have it doing what it needs to.

What are the advantages and disadvantages of the Stillson and Swedish pipe wrench designs? What do you prefer, or what do you prefer for what tasks?

I have a sort of third world issue, I have unlimited power, but water as a resource is scarce. I can only get water by loading a tank in a truck and driving it to a place that fills it and then driving back and putting the tank back on its stand, it is incredibly labor intensive.
I was wondering if /diy/ has any ideas on ways to use the power to reliably convert tainted water back into usable water. The main water uses at the moment are washing clothes, washing dishes, and showering.
My goal is to convert at least some of this used water back into clean water for washing clothes again or at minimum for use in less human stuff.
So basically boil it and distill it or evaporate and condense or what else can I do?

Winter is coming! What are you doing to stay cozy/save on heating costs?
Me? I'm currently in the middle/at the start of various projects on the house I got.
>Windows
I'm changing the gaskets, they're done and leaking heat, just gotta figure out how to adjust the windows to get rid of the remaining gaps.
>attic
Already got a big-ish layer of rockwool in it, but apparently, nowadays you're going thicker. Contemplating if I should just plaster the whole area in a few cm of XPS, which would also give me a better walking surface and the option to store some stuff, without producing stupid ass rock wool dust.
>pipes
Not really worried about pic related, but my heating system in the basement has all its pipes uninsulated. While it does warm up my basement, the fact that the basement itself isn't really insulated does waste quite a lot of heat. So those pipes gonna get covered. Just wondering if it's really worth it to shell out for armaflex, or if I can just get random PE or rock wool insulation of my local big box store, which costs half as much as armaflex and seems to have a better λ as armaflex. For armaflex, I can only find λ ≤ 0,036W/(m·K) at 0°C at the various stores that sell it, but for the cheapos, I get about λ = 0,037W/(m·K) at 40°C, and armaflex lists 40°C only in their datasheet for all their products, and there its at 0.041, so worse. What gives?

My bees are doing this. Would foundation stop them from building across two frames?

Hello /diy/ers
Some stupid asshole put a box garden bed under my windows.
Now I need to paint the wooden window frames because the paint is only hanging on due to goodwill.
The garden bed is 20cm high(ground level-up) and 53cm wide (from wall to edge of garden bed)
I can orient the ladder in either direction, but either way only 1/2 of the ladder legs will be in the garden bed.

What can I build or do to support the ladder over the void?

The top of the window is 2.5m off the ground so I need to be able to reach it

There's a fucking cricket somewhere in my basement that won't shut the fuck up. I'm going absolutely insane. How long does it take these fuckers to die of starvation? Why won't it shut up!? WHAT THE FUCK is the matter with these wretched creatures. MOST ANNOYING SHIT EVER. WHY DO THEY MAKE THIS NOISE CONSTANTLY

HOW CAN I LOCATE AND GET RID OF THIS THING? When I go down there it shuts up but otherwise it hasn't stopped chirping for like 4 hours now. I'm going insane! WHAT DO I NEED TO DO TO PREVENT MORE?! FFS i'm ready to buy a chicken coup and get chickens to get rid of this shit. I'm about ready to burn my fucking house down that's how annoying this little fucker is

I'm replacing my dishwasher and what a pleasant surprise to find copper. The pipe basically follows the arrows from under the sink to under the cabinet floor to out the side, and I need to get the inlet to about the circled area. Should I:

>1. wrangle the copper to the new inlet position and get an adapter for the threaded end to what my dishwasher takes
>2. cut the copper where it comes out of the wall, shark bite adapter to braided steel hose (I think this is my preferred option even if it's the least proper)
>3. start by unscrewing the fitting from the cast elbow and hope really hard nothing else breaks... probably end up replacing the valve at that point

Would a locking gag that forces quacking be feasible? I'm thinking a simple duck whistle incorporated into one of those gags with a breathing hole.

Mostly looking for what kind of gag would be best. An o-ring or spider gag seems like a bad idea but something that fills your mouth would probably work! My concern is that breathing holes are likely too small to fix the whistle into. Worst case scenario maybe drilling through a ball gag?

As far as I can tell by looking at eBay and Amazon and aliexpress, I've been completely screwed by the Boomer I bought my KS-RT70 and XL-MK500 from, because he cut the stupid proprietary cable that these units need to connect to each other and I can't find one anywhere. At this point, I'm starting to think that this type of cable doesn't even exist anywhere else but for this one specific JVC head unit produced sometime in the 1980s.
I'm at least glad that the tape deck works, but I don't see a point replacing the failing CD player in my car with a working cassette player and a CD player that I can't even use.

Is it even possible to make this cable myself? Do one of you somehow have one laying around that you could throw up on eBay so I could buy it? Or maybe one of you guys are way better at internet searching than I am and are you able to hunt one down?
Did you know that if you spend enough time on eBay uselessly searching for a specific type of cable that they will start to suspect you're a bot and make you solve captchas? Hahahaha my life sucks...

The closest I have found, is this, this thing appears as if it would allow me to physically plug the head unit into a 13-pin cable that I have already, and plug that keyboard into the CD changer, but there's no possible way the pinout is correct on this, right? https://ebay.us/m/TlR63f

ITT: Share your home media setups. Because fuck all these subscription services.

I'm using picrel on an old CRT I have in my house to capture that 90's era programming. I've got a Pi5 with a 2TB NVME connected to it, running 4 channels at the moment. The whole setup was about $250, if memory serves. The case in picrel fits the Pi perfectly, and then I run an HDMI to Coax adapter out to my CRT.

What are the shittiest tools you have ever used?

Some retard in my apartment complex seems to have apparently disintegrated into a pile of rotting flesh and dust that's being eaten by a million of these niggers at once, so they spread around the whole building and spawn in every shelf and any drawer that I open 24/7.
They seem to have set up an outpost in my apartment and live in each and every crevice that my landlord left open, of which there are a few that I really really don't want to touch since a lot of shit in my apartment is broken beyond salvation already and if I attract any attention from management I will most definitely get assblasted with rent increases since they haven't increased my rent in 7 years because I fly under the radar.

But I really can't fucking handle them anymore and decided to something about it, so I
> bought an oversized dehumidifier that I will set to something ridiclously low and run 24/7 once it arrives, since those niggers need moisture for breeding.
> moved most of my daily operations into public spaces so I spend as little time as possible inside of my home (showering at the gym, working in the library etc.) in order to fuck up their food supply as much as possible. I basically only come home to brush my teeth and sleep at this point.


Is there something else that I can do that DOES NOT involve calling a "" professional"" exterminator who will ask for a few hundred wagie tokens after spraying some shit around for 5 minutes or gaslight me into thinking that tolerating these disgusting six-legged niggers is acceptable and widely common because "muh mites and spores" or some other made up bullshit? Do I just /diy/ mustard gas from cleaning supplies instead?
What can I do that's actually effective and not boomer-tier bullshit like spraying random soup ingredients around your walls and placeboeing yourself into thinking that it somehow works?

For clarification, it's not only silverfish but also that other annoying critter that looks the same but is worse for some reason.

There hasn't been an /hbg/ thread since the site got taken down. Tell us about your latest batches, recipes and experiments. What is your definitive summertime beer?

hey /diy/, i'm painting some tile and i've never done this before.

i've cleaned, sanded and done a coat of primer, and the back of the can says i should sand it again between the first and second coat. why? is the can full of shit, or should i actually do this?

This is the worst of my windows.
Will post 9 pictures total to start with.
The other windows I can repair myself.
This one is rotting, and you can see the wood has .. shrunk? Or like sucked-in in places.
Maybe it's where the rot is collapsing the wood.
On the inside in one spot there seemed to be a lump of fungus or something which has grown on the inside of the window.
I need to keep this window functional and beautiful for another 2 years to keep my wife happy until we can afford to replace it.
Also there's an owners corporation over multiple properties on this one property, so I need to keep those dickheads happy too.

As you can see, there's clearly already been repairs in the past (not by me) as there's already old filler of some kind been applied.

My plan so far is
>pray to the gods for a sheet of glass not to come flying out at me
>dig out all the rot in the vertical thingo
>spray with wood hardener
>inserts some 18x18mm H3 treated pine as structural support
>add small L-bracket where it meets the horizontal window thingo
>rebuild the rest of the vertical with builders bog
>repeat the same process for the horizontal, and attach the horizantal H3 treated pine to the L-brackets for support
>make it all beautiful & nicely painted etc afterwards
I've got a shedload of tools and gear already so I'm okay on that front

How much of a pain in the ass would it be to buy and renovate something like this? And how would you do it? It sits on 4 acres, has a small creek and well, small EU village and it's for sale for 20k.
It's the only feasible way for me to get into the home ownership game.

How do I not die from sewer gas? I want to go into an old timey sewer like picrel and it has ventilation shafts all the way and the tunnel is large enough to drive a car into and is level in its entirety (entrance is from the side if a ravine so one does not descend at any point)

I want to make a board game. Nothing super professional and I have no delusions about it, but it would be nice if I didn't have to write out all the cards by hand.

Just curious if anyone had any suggestions or ideas?

ever just start doing shit with no plan?

I need to unload 24 pallets with bricks on my property, but I cant drive a big truck on it because there are power lines next to the street on my side. A truck with a crane wont fit under them. I also cant get them delivered and unloaded onto the street.

I was thinking to build something like pic rel, but it has to be free standing.

Constrains:
1: It needs to be movable so I can unload several pallets without having to move them.
2: It has to be done on uneven terrain (grass)

I thought about a double A frame with car wheels that are adjustable in height so I can compensate the terrain.
The connectors would be made ouf steel where I can just slide some lumber inside and bolt it down.
Has anyone ever done something like that?

>Option B, get a forklift, but they are expensive and/or might break down
>Option C unload the pallet by hand but that would take a lot of time and effort

I need to unload them as fast as possible because I need to rent a small truck to get them from the store. One pallet is about 1 metric ton.

wtf don't they make 11" toilets??? now i have to tear up an entire brand new tile floor because they keep changing things to sell more toilets

The current toilet situation is no longer a viable option in my home. A second toilet is needed and I refuse to pay literal thousands to have a plumber do something I could do.

If I know the tools, equipment, supplies and steps needed to carry out this project, then I don’t understand why I couldn’t do it myself.

I’ve tried looking up some (how to) videos and information about how to install a toilet in a closet from scratch so to speak but have had no success.

Everything I’ve read seems to only be geared towards repairing, replacing or simply fixing an already existing toilet.

I need to know how to do the whole thing but have yet to find any info. I can buy the toilet, the tools, supplies and everything else that I need, I just need to know how to do it.

The house plumbing is all PVC, I need to drill a hole in the floor, in install whatever is needed, put a toilet in, run a water line to
The toilet and tap into the main drain line. Can anyone point me to a book, website, video?

My dang ol' original 3DS has paint chipping on the d pad, and I want to seal it so it doesn't progress. I want to avoid replacing the buttons entirely because it involves almost full disassembly and the 3DS is fiddly. What sort of glue or resin can I use to paint a clear cap over the cracks? I'm picturing something thin that I can paint over top in a few layers to build up a smooth flat coat. Or what would you suggest?
