That is same jaw in all the pics
Simplicity I admire you perserverence with this endeavour , Have you tried undoing the removable jaws from the main jaws and reversing them,as if you wanted to hold a large flange or such. I am not familiar with this machine ,but the reversing will still allow you to chuck up your test piece ,albeit on a shorter section of jaws , I assume the jaws are held together on the locater step by one or 2 cap head bolts. Before you start try and see which jaw is the culprit,and after reversing see if its the same one or its improved :). In use three jaw chucks can get a strained and even bell mouthed ( slightly wider at the tailstock end of the jaws) this can happen from holding short sections of work at the end of the jaws ,the pure mechanical forces of tightening on the front section of the jaws can eventually take the jaws out of parallel , not easily seen to be sure , it just means at times you have a fuller grip on a workpiece it can be out of true . I recently upgraded my baby sieg C3 to a 4" 3 jaw chuck,of course it was out a bit , so I simply set up a dremel with a suitably mounted stone in my tool post and ground the jaws true , its as good as gold now , at least for my purposes hehe, Doesn't hurt to master the 4 jaw if you have one though :) cheers ~ John
