J head Bridgeport, and it has .0002" runout at collet but .001-.002" runout 1" from collet. This is quite inconsistent changing every time the collet is removed and replaced. I tried a friends draw bar and the problem was reduced by about half. Could this be the fault of an aftermarket drawbar or something else entirely? Does anyone have a drawing or dimensions for an OEM drawbar?
