COLLET numbers

[Pete Wass]

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.

Good luck.

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

Pete,
I believe you said in a previous thread that your Lathe has the 1 3/8" (or slightly larger) hole through the spindle. If that is the case, it should use a 5C collet provided no one has changed the collet closer from what Southbend sells as original equipment for those.

Happy Shooting,

Yes, it is pretty good size

Yes, the hole in the spindle is at least as big as you mentioned. I was thinking the hole through the spindle is 1 9/16" but could be wrong. I am not at my lathe just now to chack anything.

Thanks,

Pete

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.
