I'm building a coal fueled furnace with the goal of melting steel.Anyone know where you can buy crucibles suitable for that kind of temperature? I'm in northern Europe and I've done some searches but every large crucible is so expensive ( 70€+). Am I just getting expensive search results or do they actually cost that much? I'm new to this type of stuff, does anyone know a good supplier for steel melting crucibles in Europe?Thanks in advance
Alternatively could I make my own? I have good access to natural clay. I mean they managed to do it in medieval times
>>2897101>70€>expensivethat isnt expensive by any measure. Also, the one in your picture is a graphite crucible not clay. Steel can't just be melted in any open side container bc it reacts with the oxygen in the atmosphere. Steel is an advanced level metal foundry material, it sounds like you need a bigger budget and to learn more about the subject to do what you want.

Hello /diy/ my philips air purifier bit the dust no pun intendedthe repair shop is asking me at least 60 bucks to fix it with genuine philips parts but a replacement considering the price of the filters it's just a little more expensiveSince it's a glorified fan in a nice enclosure is it possible to bypass the logic board and connect the fan directly to a something that will give it the right power and an on off switch?I don't know shit about electrical engineering but it couldn't be that hard to power a fan, right?The purifier also came with some smart features like dust sensor, a reminder to clean the filters wnd power settings that i couldn't care less since I used to keep it running on minimum 24/7 in my room bedsidethank you for your help anons
>>2893739>so I guess a simple power supply wont be enoughlooks like a very standard AC motor at 120V (or 240V for the yuro cucks) with multiple taps for diff speeds, just like a desk fanneeds a 1.5uF cap at 450V between 2 wires, which you can determine by backtracing the pins on the circuit boardan AC voltmeter, and a willingness to die for a cause, would prove helpfulbest guess is you apply 120V across the 3-rd and 6-th, or 3-rd and 7-th, wires to power it upto avoid burning things up, i'd put a high-wattage bulb (150W or better) in series with the power wires to limit current
>>2893628How long did it last? I have a generic noname one that has been running 24/7 for years, they've discontinued the filter for it so I've been looking into building my own or modding it to fit cheaper amazon hepa filters.
you can buy a 'pc fan ac adapter' and power it with a (quiet) pc fan
>>2893628so you failed to mention exactly what parts they need to replace. also did you try to find the part online and fix it yourself? most of the "repair charges" is labor. parts are cheap for repair places they make their money on charging you for their time and labor.

A container can support hundreds of tonnes on top of it, as this is what it was designed to do.What if you turn the container onto its side, so that the earth is pressing against the panels that are designed to take weight and pressure?Any thoughts? I plan on burying mine later this summer.
>>2896932Of course not. They're all lying to you because they don't want you to succeed. You should totally do this and move in full time. Be sure to live stream yourself during the first good rain. For science.
>>2896126>A container can support hundreds of tonnes on top of it, as this is what it was designed to doNo, only in the corners, thats why theyre stacked in such a way.But really using a container the only benefit you get is that you get an instant hull which is literally the easiest part to build. Also radiation would seep through so youd need another layer of lead or so.Just get 60cm thick reinforced steel concrete, ghat keeps out all radiation

Go for it OP. These people saying no are simply trying to trick you out of following your dreams out of jealousy. Do not listen to them.
This might be a better option OP
How hard do you think it would be to convert a small room into a sauna for somebody who has used a miter saw once under the supervision of his father 10 years ago
>>2895760you're a cultist
>>2894088If you got a good method to dry it out after use, that is true.But if not, then the excess moisture trapped as air moisture has to go somewhere when the carry capacity decreases and the dew point increases. Heat and steam? Easy.Ventilation, and moisture barriers? Harder
Google it. Here in Finland most people have a sauna in their home, and the most common method is urethane panels with vapour barrier on the inner walls, combined with an "aluminum" paper type vapour barrier and then paneling. Good air circulation is also important, so an exhaust from inside the sauna, and not turning the stove off until you actually leave the sauna, making sure the sauna dries out with the residual heat. Its really not rocket science, if you can manage wet spaces you can manage saunas.
The outer layer is just decoration. Sauna starts with good ventilation, the oven needs air. You also have to have ventilation to the steam to eventually escape.You want moisture damage? No? You must isolate it with moisture protection then add plastic layer to walls and roof. Tiles on floor. Then you can start the wooden decorations.

What’s the story on these big ~1000w, ~3000rpm corded handheld drills? Who uses them for what? I thought speeds that fast were only for really small bits in soft metal, where you’d be using a drill press or mag drill or something.Or conversely, why do cordless drills usually top out at ~2000rpm?
>>2895621>For drilling holes into concrete or stone walls??????SDS drills do that much better for a similar price
>>2894022>you’re retarded… your brain obviously cannot model the forces in the joint. Mine can’t either obviously, or else I would be explaining them instead of just seething.. but I feel like it’s right based on my limited experience.
>>2888734That 1 and 2 you see right there in the gearbox housing is the two different speeds. Toggle switch on top is the hammer setting. Back by the motor air inlet is the forward-reverse switch.These suck balls for hammer drilling compared to a rotary hammer.
>>2895718The forces in the joint are he screwed into the end grain on both sides of the table leg. That means he needs a 5" screw designed for connecting 4x4s to get any purchase in the splitty end grain. More importantly, it's a rejection of the fundamental challenge of joinery, distributing stress away from weak points like the end grain. Putting the leg inside the box frame means you're screwing across the grain into the leg from both directions. Looks like a troll image with the insanely rough cut on the table leg.
>>2896145I was mocking the joint, not defending it>it’s a troll imageThen I’ve been le epically owned I guess

Are there any products already made in mind to run power from the car battery into the dashboard for a usb hub or hub with wires/ports for different voltages to power aux stuff like usb/wire gps for anti-theft tracking, etc? Most products out there go into the odb port or only have wiring for 1 device from the battery to the device, but I want to have the option to plug in something into a usb port in addition to a wired connection, etc. Do any products like this already exist that allow you to DIY your own car appliances? Nothing 110v, just stuff like usb/car gps device, etc.
>>2896222>Are there any products already made in mind to run power from the car battery into the dashboard for a usb hub or hub with wires/ports for different voltages to power aux stuff like usb/wire gps for anti-theft tracking, etc?you want to try that again, this time while not high on crack.
>>2896222
This?https://www.ebay.com/itm/233887235068Or this?https://www.ebay.com/itm/334174953699
you mean a 12 volt outlet? If yes. there are thousands of options.And why are you wiring straight to the battery? You can tap into, or even use unused parts of, the cabin fuse box.
I don't think I've posted since the purge a few months back. Here to answer any stone related questions. >Been working with stone for a few decades, running my own company for most of that time>My company mainly does repair work, but I have been a stone slab installer, fabricator etc. I also consult and do some layout/design work>Here to answer questions about stone selection, repair, applications, maintenance etc.>Happy to answer any questions for our budding entrepreneurs, contractors etc. regarding running a small business working with luxury products/clientele. I won't bump this thread, I'm terribly busy at work but will do my best to check in daily
>>2888861>stopped installing as my main work I figured this was the caseThe only thing I dont like about schluter is thinset is not waterproof and they use it to put the waterproof banding down. It takes 4 days to wick across it. Not something that happens in regular showers which can dry out between showers. However steam is much more aggressive. >allowed to cureNo they put the tile up, broke thinset ridges and then hit tile with a viberator, then put the weight on with no cure
Hey man, I'm thinking of getting this sort of job. I have a stone cutter literally by my house. I'm not sure what kind of job he does, but he has massive slabs out front where he works. I'd personally like to get a job there (I'm in the North east too, so it might be you lol). What might/should I say or do and such to get in? Really interested in this. Thank you
>>2887157how do i find a vendor that will sell me boulders/ pillars for carving? not slabs or pavers but large blocks?
>>2888740not OP but you can make picrel with an variable angle bridge saw. you can rent these at home depot for 80 for 1 day or 300 for a week. it is not difficult at all. i was a complete beginner but i was able to skillfully cut 300 miter cuts for a paver veneer project i posted on a thread here. the most important thing is to buy the correct saw and know what side of the stone chips the finished side the most when cutting. that said, some very important things to consider. the thicker the saw the better it is at stabilizing vibrations, so a pearl abrasive saw sucks because of how thin it is. TURBOMESH DIAMOND BLADE ALWAYS no other option. i really liked the cheap diapro saws i used. affordable and comparable to most blades on the market. that said, it depends on the stone and if you look at the options on Diamond Tool Store, there are a lot to choose from. these blades are expensive and only worth if you are looking for longevity. lastly, use knife grade epoxy and miter clamps to glue the stone together. i used RIVO 50 2 part to glue my project. only thing that i should have known is that the 50 means 50 minutes before tacky, so it look me weeks to glue up all the parts because i should have gotten the RIVO 20.also, there’s a lot i did and didnt like about my work in picrel. travertine is very flaky and chips easily so it wasn’t perfect knife corners like i wanted, the fact that they were inch thick pavers also made it difficult to get a good miter that fit together tightly, so some edges the epoxy shows. take aways: choose a harder stone
Best thread ever very helpful as I'm ordering countertops.
I'm looking for plans and ideas for a woodstove type heater for a 12x14 room. I've seen random bullshit posted in forums and YouTube. Can't make sense of any of it. I've also come across rocket heaters/stoves that are shown as the next coming of Christ but to me feels like a gimmick. What I'm looking for is tried and tested plans that don't burn your house down don't kill you in your sleep due to CO poisoning. And those could be either traditional stove type or rocket stove type. Also something that would burn efficiently without using a shit ton of wood. I need to burn it mainly for sleeping as I have a traditional mass heater in my living room. Any ideas ? I can weld and have access to basic metalwork tools, nothing fancy.

Not DIY, but a heater.I want an infrared heater that is small, portable, quick to turn on/off, emits directed heat, and would be safe to place e.g. on a couch.Most IR heating panels will do what I want, but they are at least 60x60cm and are often supposed to be mounted on a wall with no convenient way to place them in random locations.Some panels have retarded non-directed design, i.e. they radiate heat at the front and and the back.Heaters like pic related (this one have a marble slab inside) accumulate and release heat instead of just emitting it, so you can't just turn it on and get instantly cozy.Any recommendations?
A spiral wound heat exchanger with the tea/soup pot out of the fire could be folded out of one piece of sheet metal with crimped/brazed seams only on the outside. Since liquid holdup will be too low I either have it flow through once or it could recirculate using a thermosyphon or steam bubble-airlift pump.
What's a good 3D printer to buy? My budget is around $200. I'm an mature, & I'm mostly gonna use it for printing minis & knicknacks
>>2896570>The best diy 3d printer?Probably a hot-rodded Voron tailored to your specific use case.>Which is the least expensive and smallest to make?This is a very different question. The usability of cheap purchased printers and the time need to DIY means that DIY printers are mostly aimed at higher-end markets (e.g. Vorons). Some Voron Zero kits are fairly cheap (though more expensive than many ready-made printers).

I live in a basement of a 20 year old house. I just heard two large bangs from the ceiling, about 15 minutes apart. Should I be concerned? It was much louder than your average duct noise.
>>2896523I heard a joist in my attic snap. I waited nearly a year to get around to sistering in some wood.Keep an eye out for anything sagging or bowing every few months over the next year. You can shine a bright flashlight flush against the ceiling, dips will cast long shadows.
