I've no idea if I've come to the right place, but guess so, /k/ doesn't seem appropriate. I am currently thinking about making some semi-usable armour for post-apoc events, and titanium came to mind when friend told me about some scrap titanium, since I know soviets used it for some personal armour. I fence sometimes, shoot stuff, like to do silly things, ocassionally gain a little coin from leatherwork and my trade is blacksmithing, as to why I came to this idea.
But I know pretty much crap about titanium apart from the basics. So... can titanium actually be forged without damaging it? And can it be hardened, somehow? I've read somewhere that it has about 35HRC annealed, but that is damn soft for armour in my opinion, much less for stabby slicy things. Can someone offer some advice? Also, what grade / kind of titanium would be best suited for this? Thanks.

I'm looking for some nut drivers (I think that's how they're commonly referred now), I've known them as tek bits also.
Basically 1/4 bits for an impact driver, for hex headed screws.
I have many that are magnetic, a little magnet in the centre of the bit to retain the screw.
I had one that I'd like to replace, it was in my drill case when it was stolen. It didn't have a magnet and was for stainless steel screws, it basically had a metal ring around the outside that acted like a spring clip to hold the screw in the bit, I can't remember where I got it from and I've tried all kinds of search terms on google and I can only find the magnetic type nut drivers.
Can anyone help me find what I'm looking for? I'd imagine commercial roofers and cladders are more likely to come across them, and metal workers alike.

So I have read a bunch of books on door construction and I have finally come up with my own design for a somewhat sound proof door (RwDB=40db).
My idea was to glue a frame of 27mm or 18mm plywood (=VP(blue)) onto a sheet of 18mm VP. The recess in the center would be filled with 27mm/18mm MDF (brown), followed by another layer of 18mm VP. A mitered frame of mdf would then be glued around the edges of the sandwich, which should allow for profiling of the doors edges, without affecting the finish. Sheets of 4mm MDF would then be glued to both sides of the door, so that a smooth finish can be achieved, without any interference by the grain.
Rate this construction and tell me what you would do differently.

What is the best way to generate 8400 watts of electricity? Short of buying a fuel burning generator that is.
I'm trying to go off grid. I've worked out my average daily consumption to about 25-26 KWH per day. Yes that is heavy, but it's also counting the fact that I don't live alone, and there are 3 water boilers on the property, one of which runs about 3-4 hours a day on average, and one loafer at home all day. I also have a blacksmith forge, and occasionally use the arc welder for touch ups and structural welds. And electricity prices are hiking in my country, so I want to try going off grid.
Solar is too expensive. The cheapest quote I've gotten is about the equivalent of 7000 dollars without the inverters, so that's not gonna happen Any time soon, and I might do it little by little
