I recently purchased a small jewelers lathe on ebay. It is marked "Massachusetts Tool Co. Greenfield, Mass. USA". After reading several posts on this forum it appears to be a No. 700 bench lathe. The collets supplied with it (one in the headstock and one in the tailstock) have internal threads and the corresponding external threads on the draw bar are .278 major dia. x 40 TPI. I am hoping to find a source for additional collets. Of the two I have, one is marked 15 and the other is marked 35. I don't know what these designations mean.
Can anyone help?
