I am wondering what the numbers and letter designations for collets means. I have an old (1941) 10 L South Bend which has the hardware necessaryo to use collets. I loaned the collets to a gent who hs passed and my collets are no longer available. How do I tell if I have a 3-C or whatever setup?
MSC Industrial supply has an extensive inventory of collets. Order the "Big Blue Book". Excellent reference.
If this works, see attached word.doc
Thanks for the replies
I located my Collet holders today whilst waiting for the Electrician to hook up my new motor. I will measure the thread size next time I am there.
On a sader note, the electician fiinally got the motor to run and reverse about 6:00 PM and left; hungry I guess. Anyway, I tried to start the lathe with the spindle belt engaged and the motor would not start. I then started the motor and engaged the belt. The lathe seems to be running slow but was able to change speed by moving the belt.
After a couple of minutes I began to smell the odor of Plastic melting or burrning. Once I smelled it it was more pungent than I realized ; am about to phone him giving him the great news

Yes, it is pretty good size

I have a suthbend heavy 10 and they take a 5C collet
Thanks for the help:
I would not have thought to simply measure the thread in the draw bar or whatever the tube the collets screw into is. I gusee I was thinking that thread might be universal; I seem to have just enough knowledge about this stuff to ask a bunch of stupid questions. Sorry
I did do something last evening that might help. I bought a copy of Machinery's Handbook. Figured that might save me asking some of these dumb questions that have obvious answers.
