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€
>expensive

that 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 intended
the 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 expensive

Since 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 bedside

thank you for your help anons

>so I guess a simple power supply wont be enough

looks like a very standard AC motor at 120V (or 240V for the yuro cucks) with multiple taps for diff speeds, just like a desk fan
needs a 1.5uF cap at 450V between 2 wires, which you can determine by backtracing the pins on the circuit board
an AC voltmeter, and a willingness to die for a cause, would prove helpful
best guess is you apply 120V across the 3-rd and 6-th, or 3-rd and 7-th, wires to power it up
to avoid burning things up, i'd put a high-wattage bulb (150W or better) in series with the power wires to limit current
>>
>>2893628

so 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.

No, 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

If 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.

This is fucking genius

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?

The 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.

not 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

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?

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).
