From your note about turning wax, it sounds as though you have
never used some of the high plastic content, very hard,
burn-outable waxes that are on the market. If this assumption
is correct, do try one of these waxes. High speed is not a
problem as the wax has a very high (360 deg. F) melting temp,
and is made to work with high speed tools. Kendt Collins wax
company used to send out a 3/4" x 5 inch bolt and nut turned out
of this wax to demonstrate what could be done. The bolt threads
felt sharp enough to cut you and the fit was wonderful. It
sands, files, drills, saws, and takes power burrs much like a
very even, fine grained hardwood. It can be turned, carved with
a knife (different than with wood, but it does carve) can be
added to if you goof and can be cast into metal if wished. (Many
casters will not cast these types of waxes((Filo Wax) as it is
very expansive upon heating and it breaks the investment. If a
fresh flask ((2 hours old) is put into a hot ((1000 deg F) oven,
and the moon is right and the barometric pressure is in your
favor and you hold your mouth just right, it casts fine.
Actually it is not this bad but it is more problematical than
other casting waxes, BUT very do-able.) Give it a try, it
may open up whole new areas for you.
My 2 cents worth.
