how would you build a cabin with a steel reinforced concrete bunker/basement?
>>
Weld up a box of sheet metal with tie in points for rebar nets. Either pour the concrete inside this box if you want the steel aestethics or put up molds on both sides so you get the steel sandwiched betwen the concrete layers. I would do the latter method since that is how they build protected buildings that might need extra safety from terrorist attacks such as embassys etc.

I was having a hell of a time splitting wood with an axe until I got one of these things, and now the tree sections blast apart with just a few strikes from the blunt side of my maul. But it kind of feels like cheating. How can I get better at splitting wood oldschool-style? Just a sharp axe and a big chunk of felled timber?

I want to make my own slow/extended release tablets to release a drug over preferably 8 or so hours, or more. This drug would otherwise only sit in the body for a few hours.

Using Google search is near impossible today after they have ruined the search algorithms time and time again. All I get are pages telling me the different types of technologies used, but no mention of ingredients or methods.

I know hydroxypropyl methylcellulose (HPMC) is used to make a supplement release over 8 or so hours, but how is this done?

Please help me

Question: Can we theory-craft a sustainable affordable method for smelting of high temperature metals without excessive energy consumption?

Also post some of the wackiest phase diagrams you've seen.

>>2555455
The near-liquid metal rapidly changes in conductivity and susceptible frequencies. "Proper" induction smelters have unique transitions which vary the coil frequency/power and can have multiple coils with phase lag to induce certain flows.

Consumer shop induction coils can be smelters but need a LOT of power or a robust insulation system to get over the hump.

i want to differentially harden chisel blades so that the tops are soft. should i quench it half submerged, that is, the belly surface with the cutting edge dropped on a shallow pool of my temper? or will that produce problems?
the other way i'm thinking of is to keep it half submerged on a shallow pool of water and then gently heat the back side after it has been hardened. or sort of like a hamon, but with the clay coating the entire belly and cutting edge of the chisel or heat it when the top portion is coated with clay.
>>
>>2555903
You may get a banana bend if you try half quench (much like a katana!). Do the water-submerged temper with a torch instad.
>>
>>2555921
thanks. it seems to be the easiest and less awkward way to do. i'm just worried that the heat might draw farther down than expected since only half of the thickness is above the water while laying flat.
i'm trying to replicate the old laminated chisels and plane blades where there is less of the hard steel to hone.

Why would you bother with this? If you're getting mold behind furniture, your problem is ventilation. Modern retards like to close every window and leave no vents for moisture everywhere because heat will escape, and then act shocked when their house gets filled with mold. Just crack the windows open a bit in winter.
>>
>>2555442
I think the problem might be a bit too much, we have big bay windows at the front of the house that might let in air and moisture

>>
>>2555764
This isn't how moisture works. The outside air is generally less moist than the air inside your house. You get mold because you and the shit in your house produce excess moisture, and with no ventilation for it to escape through, it just condenses on any cold surface like exterior walls or windows.

Hey /diy/ my room is an add in to an already 100 year old home and I have to deal with tons of dust. The ceiling Is made from some shitty wood panels or something, is this where it all comes from? Can I spay some kind of sealant to help prevent excess dust?
>>
Probably all the lead paint dust, aspergillus, and rat feces/dander that come with a house that old.
>>
Hard to say where the dust is coming from, without knowing the full setup. Do you have carpet?

If nothing else, you can try putting some clear silicone caulk in those cracks.

About five years ago, I switched to down comforters, and they're comfortable, and awesome.
But they make a huge amount of dust. I have central air, and I run an air purifier (some Honeywell unit, basic HEPA filters) in my bedroom to help keep it under control.

the thing about putting drapes or curtains over it is that with the condensation that builds up they could get funky and gunky
plus the landlord would probably cheap out and get something flimsy rather than thick and insulating

New Questions That Don't Deserve Their Own Thread, doesn't look like there's one active.
Is there a maximum size that you can realistically make a carpet patch for?
I've got a big section of floor, maybe 2'x10', that's underneath a cabinet. I don't need the storage space and it makes the room feel smaller so I'd like to remove it. Problem is, the previous homeowners laid new carpet down on the entire floor except for underneath the cabinet, so when I get rid of it I'll have a big patch of mismatched carpet. Assuming I get a carpet that matches, can I make a repair on an area that large, or will it just fall apart after a few months?

I’m gonna try my luck here. I have a denon stereo amp that’s hooked up to two bookshelf speakers. I recently could buy a polk center channel for cheap, and I received my dad’s Yamaha 5.1 AVR from the early 2000s and a subwoofer. Sadly the AVR doesn’t seem to have preouts.

Here’s the deal :
I want to output the Left and Right speaker signals of the AVR to the denon stereo amp, while the AVR powers the center channel, subwoofer and whatever else I might get.

Basically, I will keep using the denon stereo amp to casually listen to music, and I will use the AVR for movies and games with the denon amp taking care of the left and right speakers that are already plugged in, while the AVR powers everything else.

What kind of adapter or device should I buy ? What works best, without breaking anything ? Any help or advice is appreciated.

Also more context : I’m European, I live in a studio and the neighbors are cool with it.

Pic : what I originally planned. I have these inexpensive speaker to rca 2pin adapters, and I planned to connect the wire from the Left and Right speaker outputs of the AVR, and plug the rcas in the stereo receiver, but I’m afraid it’s way too risky.

if the compressor unit on my air compressor (large 2 stage inline ~20cfm iirc) starts popping the pressure relief on the stage to stage pipe thing when almost to max pressure and seems to have a lot of crank case pressure coming out of the vent even when just spinning it by hand, its probably fucked isnt it?
>>
>>2556227
clarification: its not like the tank relief where it stays open and keeps venting until its below a certain pressure, it just randomly pops and then closes right away when the tank is above ~140 psi (set pressure is 155-160). it never does it below 130ish and it only pops for an instant then closes.

so, there is a reason they use a square drive on your ratchet and breaker bar (where you attach the socket) as well as the robertson screw. it's torque.

if you don't need the 6 positions of angular freedom that hex nuts and bolts give you (like a screw) square maximizes torque.

> triangle drive?
the screw tip doesn't have enough meat, and would break tips off in an industrial/heavy use. i think there is some lightweight electronic products that use them (think companies named after fruit) but thats to annoy ppl.
