lost my copy of "the Metal Lathe" ~10 years ago. The best way to learn about
machinery is learn how to build one! No, I haven't undertaken such a project, but know
enough to modify existing designs at least.
You just need to hunt and peck to find the right *tricks* to do what you want to do
though. Especially w/this stuff.

" Build Your Own Metalworking Shop from Scrap ",
is the best DIY books I have seen
in along time.
if this was the case, the surfaces just needed to
be
plated, you can produce a uniform thickness by polishing.
Some sort of contraption (a lathe?) would be necessary, but
it's not rocket science I don't think. I was between
jobs a number of years ago and applied at this place in Long
Island that makes some sort of microchips. The silicon
wafers needed to be made *uniform*, and they used some sort
of polishing operation. I asked what was the tolerance, and
the guy said .0001". I figured to myself he probably
didn't really know what he was talking about and the
tolerance was much tighter. Cast iron surface plates can be
made uniform to .000025" (that's right, 25
millionths of an inch), but that's an entirely different
operation, and in fact is done - by hand - w/a glorified
chisel.
Carry on lads. I'm interested in learning
