Tried my first forge weld last month and now I get why guys swear by it.

Three post holes tell you layout but Pompeii shows daily life, so which teaches more?

That whole "volume stays the same" thing is huge, but there's another side nobody mentions. Like, that math only works if you're not burning off scale or losing material to fire. I checked my tapers once with a caliper after doing the math and still came up short because of scale loss. You gotta add a little extra, like 5 or 10 percent, just to be safe. That's the kind of thing that really changes your planning once you figure it out.
