[TheForge] Making power hammers

Yeah, I'd make the frame plenty rigid. The hammer weight isn't falling, it's
being accelerated with considerable force and that force has to be supported
by the frame. The deeper the throat, the heavier the frame needs to be too
because of increased leverage.

If you did make it too light I don't think you'd have to worry about a
catastrophic failure though. I think you'd get some very noticable
displacement between your dies, making it an unworkable hammer before it's
back broke.

It's easier to make it a little heavy in the first place than it is to
repair/rebuild something like a power hammer.
