Hello,
I have a Sjorgen 3J chuck on my Colchester lathe. I haven't had this problem before (atleast not this bad). I have a 1.5" collet in it with some 1018 steel in the collet (about 14" into the head). Well I just finished parting off and now I can't lossen the collet in the chuck! The large hand wheel won't budge in either direction. I have an oil gun for it to lubricate it and the only other time it gave me trouble I lub'd it up and I could remove the collet. This time no go....
Thoughts welcome.....
Thanks, Jeff
