I find that my MT3 spindle, in the tailstock, is very short. Without measuring, it seems there is only about an inch and half of travel. When boring I have to move the whole tailstock back or it will push the boring head out of the spindle. This means I have to move the spindle backwards and re-tighten the head in the spindle and move it forward into position for the next cut. Should I cut off some of the boring heads MT3 tail? Ar there any longer spindles that can be purchased? Thanks
