Why was brass used so much historically (and maybe presently?) for complex mechanical watches/clocks/scientific instruments? Is it just because it is relatively easily worked but hard enough not to warp? It seems like mild steel wood generally be cheaper and isn’t that much more difficult to work? Is it particularly dimensionally stable? I have no idea if some metals expand/contract more with temperature changes than others. Is the big advantage of brass corrosion resistance or what?

Not to badmouth your work it looks pretty sweet, but like I know capitalism and monarchy are bad and all that but isn't Lenin also pretty bad too?

This isn't really the space for debating or discussing how relatively bad or good Lenin/George III/Jeff Bezos are. For all we know Ambrose Burnside might be making a tiny bust of Lenin to piss on daily or use as a buttplug or somethin!!!!!

When welding metal thats 1/2" thick or bigger, I know that you should be bevelling the edges to get better penetration, should you also be using bigger rods too? Like can you buy welding rods that are 1/4" thick or bigger for doing that kind of stuff?

I'm not trying to weld anything that thick but I was thinking it seems like a waste to use 1/8" rods to weld really thick material. Although maybe 1/8" rods aren't too small for 1/2" but maybe for stuff thats 3/4" + in size.
Yeah they make really big ones. A guy I used to work in the shipyard with worked on the Iowa-class battleships when they were bringing them back into service in the 80's and talked about spending like a week on one weld because it was in some 10" thick armor plate or something crazy and using like 1/2" electrodes because the bevel was a foot wide at the top.
