Okay, I just purchased a ATS-Sjogren Speed chuck for my lathe with a D1-4 mount. When I fit it up to the spindle on my lathe is does not fit flush up against the flat spindle face. When you tighten the pins you can still see light between the chuck and the spindle at one spot are another depending on how you tighten the pins or what sequence. The runout varies between .005 to .010 and occasionaly you get lucky and it will be around .002. It appears to me the the taper in the chuck is too large for the spindle mount. When you hold it in place before locking it down you can rock it slightly in place. The lock pins are adjusted correctly and I have tried indexing the chuck in a complete circle several times but no luck. My question is, can you turn a little off the OD of the taper on the chuck or how do you guys correct this problem??? Any suggestions please !!!
