     Hmm...my 1946 _Machinery's Handbook_ tells us that:

     Rivett #4 NS collet:
     Right-hand thread
     Maximum capacity, round stock- 5/8"
     Maximum capacity, square stock- 7/16"
     Maximum capacity, hexagon stock- 17/32"
     Body diameter- 0.826"
     Thread- 0.812" x 20 t.p.i.
     Length- 3 1/2" (not including radiused end)

     This collet is listed as having been used on:
     Flather 14" and 16" cone-head (!) lathes
     LeBlond Regal 12" and 14" lathes
     Rivett No. 504-4 N.S. bench lathe

I can state that its also used on the South Bend 14 1/2" lathe too.
Does anybody sell these collets anymore? I have never seen them in any
catalog. Thank God I'm basically equiped.
