I'm highly retarded, and have been pondering for a long time on how to do 3d print assisted depth etching.3d etching.For a long time I didn't have a printer, but I do now and I am now exploring this possibility.Here's my basic concept:A piece being worked on falls onto a surface which etches it and keeps falling through it, simple as that.A jig is designed in 3d modeling software which allows a piece to fall onto the cutting surface. The jig is designed in such way that the work piece can be removed and inspected mid-process and placed back in roughly the same position.The cutting surface has a small ledge which isn't electronically conducting, this is to keep the work piece at an ideal distance from the cutting edge.In my case the piece being worked on is a standard M16 bolt.The cutting surface has a electricity conducting mask on it. Normally when etching you would use a negative mask, but in this case I will use a positive mask.In my retarded mind tinfoil works for hats so it will work for this too, so I did mask out of it and glued it in place.I bought a second-hand laptop power supply and modded it with alligator clips to have a source of electricity.Assemble the thing, put it in salt water bath and inspect results in 2 hours, then try to improve the process.What this thing is suppose to do is cut a slot in the bolt, or catch on fire and burn. This is an experiment, I’m curious to see if it could work.Comment too long. Click here to view the full text.

>>2983802is there any point in keeping more than a couple weeks supply of needs (food, water, energy, toiletries, etc) and then just rotating them? Maybe a max of 2 months? I figure that if things go so wrong that I'm not able to get whatever supply AT ALL (Or find some substitute) for longer than a few months then it's probably cuz society has broken down to mad max level, and anything I have will be stolen from me anyway. Either by some militia group or FEMA. ....and then I'll be subject to the misery anyway

Yesterday I was at a yard sale and found this. It's pretty sturdy and also a lazy susan. Should I sand and paint it or sand and re-stain it? I was also thinking maybe doing a polyurethane finish?
>>2991500have you considered painting it red, with white highlights on the top walls?
i need it
>>2991500Put your Kanye West merch in there.
>>2991501Faggot
>>2991500fuck poly.go with genuine German-made Osmo Original Hardwax-Oil.it's the best wood finish out there.
Hi I’m wanting to patch up this hole in my ceiling in a small room (laundry room). The hole used to be smaller but the drywall around it had been damaged by water and was sagging so I tore it down. I was about to put in new drywall but my mom texted this handyman guy friend of hers and he replied (after 2 days) saying that I can’t just put it in because “the truss has to be jacked up”. I have no idea what that means. The guy does meth so I can’t really rely on him for help. Can someone explain the steps I need to take to replace the drywall? If I need additional tools my budget is like $70 so maybe I can rent something. Help me bros I’m retarded!!!
>>2991251Did you fix the leak?It looks like sun light coming through in picture 1.Also, why not just screw that wood with the braces to the existing wood. As it is in the picture you are going to have an unsupported end.
If the roof isn't finished, don't do anything inside yet.... who the fuck knows what will happen and you won't see any continued leakingGo fix the roof, cosmetic shit inside can wait permanently.....That piece of chipboard needs replacingIf wood is sagging its rotten and needs replacing/sistering up...
>>2991252Why didn't you sister that to the existing cross brace (next to the vent)?And I'd suggest cutting a new piece that has a snug fit between the rafters. The two pieces (existing brace and your added piece) should not move relative to each other. Or your taoe and mud job will crack. Those brackets will loosen up over time (dab of construction adhesive would be good).
>>2992666>It looks like sun light coming through in picture 1.Looks like a soffit vent. Which should be OK. If OP makes sure it is under an overhang and screened so as not to make attic a condominium for squirrels.
That vent will look messy unless you put it in the middle of the new panel. I would cut back to the green line and just use one large panel to fill the ceiling. If you use the first two trimmers (the pieces of wood the vent is mounted to) Then your new piece of drywall will be ugly because you're trimming the edge. So cut back the ceiling all the way to the middle of the third trimmer and cut yourself a piece of drywall that will fill the space. Then put wet paint or something on the vent and use that to mark the position on the new drywall.
Is it a realistic goal to build a greenhouse from steel, curled patterns poured into moulds using molten iron made in a Temu furnace and glass, all using an angle grinder and arc welder?
>>2993585no
>>2993585Rich people like 100 years ago did this. Sometimes you can see the remains of them in tours of old mansions etc. Glass and steel work well together **at first**. But over time moisture ingress and rust become a problem. You also need available spare glass pieces when bird strikes or hail or clumsy occupants etc break glass. So highly specialized glass pieces become a problem at that point.You could make it out of standardized pieces but any company that does make that kind of thing would likely charge an arm and a leg, and may not be there when you need a replacement piece in 10+ years.Back in the days this kind of thing was the purview of millionaires and billionaires working with trades that still had a lot of life in them. Ironworkers, millrights, glass workers and other artisans. These things still exist but finding ready access to the right person when you need them for repairs or expansions will likely be a huge pita.
ice chest upgrades?
>>2993377almost all common ice chests are exactly the same thin plastic with no insulation made as cheaply as possible. only the really expensive ones are better.
>>2993395>fiberglass insulation. Newer, cheaper ones often used Styrofoamhave you actually looked in to that. I found that they have just an open space with no insulation.
>>2993499I don't have that unit in particular but this one definitely has fiberglass insulation poking out the holes in the bottom of it. I have an old Igloo and that thing was full of cork.

I needed a freight elevator for my attic, mostly for apples.I took a truck bed crane off of alibaba and sunk some M16 bolts into the concrete. I estimate the worst-case pullout loading at 3.5 kN, on a 450 kg load, before adding a 2x safety margin. The datasheet for the bonding compound said that an M16 bolt would handle it at 125mm depth. I fucked up the install and only got it about 115mm deep before it set. Should I be worried?Also, r8 my grouting job. Only the second time I've worked with concrete.
>>2993362Are you hoisting pianos by chance?
>>2993443Lol no, mostly taking old junk out of the garage that was too heavy to carry up the stairs. We have a walk-in freezer that we're going to use for apples in the near future, which we will be collecting in 300 kg palox containers.The overhang is just barely more than 60 cm, which is a half-length of a standard pallet. Therefore, a properly centered pallet load should go up without scraping the wall.In a couple years we may get a forklift, which will do the job a lot better, but we need a kludge solution now to free up the second garage.
>>2993436I recently picked up a new old stock Chisholm-Moore Cyclone 1-ton chain hoist for about $67. That has a capacity of a bit over 900 kg. A 10 foot/3 meter length of used I-beam can be had for a a couple of hundred bucks. You can buy a decent trolley for a few hundred bucks, a shitty Chinese one from harbor Freight for $80 or, if you have the ability to cut metal, make one yourself for something between the two. From there it is just a matter of hoisting the beam into the barn without a hoist and installing it.
>>2993362Looks pretty gud OP. What size winch are you gonna run on that? >>2993445Oh yeah get a forklift, they are amazing for all kinds of stuff. >>2993464Noice. I was just looking at a couple oldies/goodies I have stashed away yesterday. Also have some A frame ends I got for free that I just need to clean up and weld a plate to to bolt a beam across them and I'll have another A-frame gantry. Already have a couple others I got for dirt cheap. I don't use them much because I have loaders, forklifts, and telehandlers, that get used often, but sometimes they shine for certain applications. Really want to get pic rel overhead traveling gantry put up in the shop someday...
>>2993362unless you try to lift more than it is rated at it should be fine. ya dun gud skippy.

I want to set up a video wall at my place that can stream independent sources or combine into one image across all 4 screens. I can buy a 4x4 matrixer but the issue I think I am going to come across is remote controls. The TV remote is going to control more than 1 TV (e.g. I want to turn TV "A" off but TV "B" also turns off), and similarly if I use something like a Roku stick for the HDMI inputs on the matrixer, the Roku remote will control more than 1 stick. Any suggestions on how to approach this? CPU with 4-HDMI output and use separate windows for streams?
alright dudes help me out here cause I'm driving myself bananas over this>sets of outlets tied to 2 different breakers were working as of last fall - as of this spring none worked>breakers were not tripped and did not trip when pushing the test buttons on the outlets or the breaker itself>figured I needed replacement breakers (as seen in image, the #2 and #3 from the top)>same fucking issue, when I press the test buttons on outlets/breaker it does not trip the breaker>however at least this time the outlets shine their red light so power is at least getting to themI've reset all outlets that have buttons, taken apart and inspected each outlet and does not appear to be wiring problems. I don't even know where the fuck to go from here, appreciate any advice!
>>2993202The test function of the outlet should not trip the breaker. It should only turn the outlet itself off. The test button on the breaker not turning off the breaker is an issue though. Do you have a multimeter? Have you confirmed that proper voltage is reaching the outlets?
It reads about 40% power for power coming from the middle 2 breakers. Top/bottom ones have 100
>>2993202>willingly using afci (always fucking causing issues) breakers Its probably some neutral nonsense since those things will not work if you're sharing a nuteral with any other circut.

What are you really upset about, people discarding living in a shipping container?>Just finished my third winter in a ~500 sq foot house I built.You do you, but would you concede you're in a vanishingly tiny minority of people willing to live in what amounts to a 2-room dwelling? And what permits were you dealing with? Even for rural parts here permits are a joke, who's gonna know if I don't wire up my guest house incorrectly?
>>2992106>willing to live in what amounts to a 2-room dwelling?Would you rather own a dwelling and get rich by saving money, or would you rather lose everything when you can't afford your five bedrooms? How much room do you need when you live alone and jack off all day?
>>2992117>How much room do you need when you live alone and jack off all day?Sometimes I enjoy jerking off in various rooms, thank you very much. I also have no debt, bought the house when I was single, its gone up nearly $100k since I bought. I can have friends and family over and not suggest they sleep on a couch 10 feet from where I masturbate in my bed. I also have a garage to park my truck in, I'm close enough to town, I have a lawn to mow, a garden to tend, and happy little flowers I can decorate my front lawn with and impress my neighbors. Whats the use in getting rich while living like a pauper your entire life?I get it man, some guys (like Ted) are fine living in a single room house like a studio in a very spartan lifestyle however the overwhelming vast majority of people simply are not.
I'm not into the 80k tiny house "totally not just a trailer bro" thing, but a small cabin build seems economical and like a worthy goal. Is the only way to avoid permitting and red tape to keep it very small? Most municipalities I've looked at require permits for anything over either 120 or 200 square feet.

>>2993104>boomer
>>2993097
>>2993097I have to agree with the other anon. At least in central europe the market for anything used has completely deteriorated. Any auction is scalped by full time pensioners "trying to earn on the side" and sandniggers shipping everything they can get their fingers on to africa or god knows where. Even the usual 1€ deals go down for literal scrap metal and parts. Nevermind most of police and customs auctions running at 11am work days. It's pretty ridiculous for a young working person.
