Well I got my new Jet 1642EVS the other day and had to order a new adapter for my chuck since my old lathe was a 1"x8 and the Jet is a 1.25"x8. So while I waited I did some spindle turning and was just getting the feel of the new beast. Today I got my adapter and spun on the ol chuck for some small lidded boxes I was going to try. I turn the lathe on and the chuck is wobbling! Bad enough that I could see it right away. I thought something must be wrong with the insert or maybe the chuck got dropped or something. So I put the chuck back on my old lathe with the old adapter. Ran true as can be as checked with a dial caliper. So back to the Jet. Check everything with the dial caliper and the needle didnt even move, the Jet was also true as can be. So not knowing what to do I spun on the faceplate that I got with the Jet. It wobbles too!! arggggghhh!! How in the world can the spindle check out to be perfectly and I mean right on the money true but yet anything thats threaded on it wobbles. Could the threads have been cut wrong on the lathe? Both the faceplate and the chuck run true on my old lathe. This is making me sick to my stomach. Any ideas guys??
