I was wondering if somone could tell me why I would have runout on my 3 jaw chuck. I have .005 inch runout on my lathe chuck. There doesnt seem to be any play in the spindle. The runout seems to be with the chuck itself. I have a 16 in Standard Modern Utilathe with an 8 inch Pratt 3 jaw chuck D1-5 mount. Is there a way to fix the jaws so as to eliminate the runout? Is the problem in the jaw threads? What about if I take off the chuck and rotate it to the next pin hole on the backplate? Would my problem be worn jaws? They seem to be in good condition. I am new to lathes but this runout thing is driving me nuts. Any comments or suggestions????
