Well, the 4 1/2 MT to 5C adaptor came in today. Now I need to make a draw
tube when I get the lathe together after completing varidrive repairs.

The ideal solution would be something 1 3/8 od with enough meat in the ID to
thread for thread for the 5C shank.

I found this but cheaper solutions would be welcome.

I repaired a number of 5C drawbars using 4130 tubing from Aircraft
Spruce and Specialty. http://www.aircraftspruce.com/

1.375 OD and i don't remember exactly what ID I ordered but .090 wall
thickness comes to mind.

When you measure a 5C collet you will find that the OD is 1.235 and 20
threads per inch. I looked high and low for a 1.250 x 20 tap to no
avail. Finally i called MSC and talked to a fellow there. He made a
call to South Bend and in a three way conversation I learned that S.B.
made the threads 1.250 x 20. Standard tap in slightly $$.
