Check your Yellow Pages! Any machine shop (not welding shop) can turn tapers
and threads. I would use untreated 3/4" drill rod. It is straight, perfectly
round, and stiffer than cold or hot rolled steel. And machines great. The
socket diameter for MT2 is .700", so a .750" rod is just right. A cantilevered
18" rod is going to have an upper rpm limit, as you have discovered! Dan

After several attempts myself trying to rig something that might work I've
decided I need part of it made by someone more capable.

The basic component I need is a hard steel rod 1/2 to 3/4 in thickness maybe
18 inches long. One end of the rod needs to be milled with a #2 Morse Taper.
The other end needs to be drilled and taped to accept threaded fittings
probably 1/4-3/8ths but any common thread will do.

I can get parts from MSC but assembling the rod from parts will not be as
cheep or as strong as making the entire rod from one piece.

The #2MT needs to be accuratly centered so there is no wabble in the rod when
my lathe is turning.

Can anyone recommend someone local to Denver or not that can make this?
