We spent the whole dang afternoon getting the 16" hydraulic chuck of the Mazak M4 lathe. Had to make special tools and drill out bunged up bolts. We took the chuck off trying to figure out why we're only getting about half the stroke ,0.100" vs. 0.190" that the jaws are supposed to have. I'll be a cleaning the whole unit up tommorrow. Swarf plugging things is at least part of the problem. "The Kid" is going to find/modify all new special metric bolts for everything.
Our best guess at this point is the draw-pipe needs to be shorter. By tightening up the threads at the hydraulic cylinder. Our question, how do you set the length of this properly?
Or, is there another possible reason for not getting the full stroke?
