Re: [CAD_CAM_EDM_DRO] Re:W.E.T.Rails-heat treat

Hi Dave and All:
If someone needs to heat treat their rails they need to know to
put a tapped hole or a cross hole near the end so the parts can be
hung during heat treat. The people who make gun barrels found out
that by hanging the parts vertical the natural weight of the part
help to keep the parts straight. Also, if you do not harden the
parts all the way through, you just put a hard case on the outside
for wear and leave the center tough the parts will stay straighter.
Nitrate (I believe) harding will give you the best of both worlds, a
hard case for wear and a tough core with little if any distortion.
GOD'S BLESSINGS
