Soo... I finally received some collets for my new beall collet chuck. I was all excited that this thing was going to solve all of my out of concentricity problems. Also in the mail I received from BB my two brand new berea mandrels. So I clean the chuck and the collets from the little bit of sticky shipping gook on them and mount the collet and the A mandrel on the lathe. To my suprise there is obvious wiggle in the mandrel. Soo.. I thought maybe it is the collet so I try changing the collets and putting in the B mandrel. Same deal. Hmm? Lets try the pin chuck I have, yet another collet, yet another wiggle. So... what could be the problem? Think its my jet mini? I have cleaned all the threads on the mini to get off any gunk that might have been on them. Also cleaned the mating surfaces where the collet chuck and spindle meet. I'm stumped. I don't have a dial indicator unfortunately but my dad says he has one in the garage so hopefully tonight I can see just how much runout there is and let you know. Oh and BTW it looks like the mandrel, pin chuck, etc. is running parallel to the axes of the lathe just a little off the center if you know what I mean. Anyone have any ideas?
