[TheForge] Repairing power hammer dies

[Ralph Sproul]

	........Or do it the sleazy way and weld a shim on the bottom to get a few
more miles out of it.

Thos would seem to imply that at the bottom of its stroke with new
dies, the ram is hanging on with but an inch of metal.  I find that case
to be highly doubtful.  Do you mean something else?
I mean there should be a safety mark on the ram.  If you take an inch off
the
top and bottom dies the ram could over extend.  I don't know how the Import
hammers are but on Nazel hammers there is a safety mark on the ram.  If the
ram
extends to far past the safety mark the piston will bottom out inside the
cylinder causing a very big problem.  I think stock Nazel 2B or 3B dies are
1 or
1-1/2 inches taller to avoid knocking the ram piston out of the bottom of
the
cylinder.  If you grind or machine that safety margin out of the dies its
time
to replace them.
