Hi Ian If you strip the spindle in the headstock there us a mod to help with stability and finish by fitting a secondary thrust bearing. It is a flat needle roller bearing with two hardened thrust washers they fit between the back of the chuck location diamiter and the bronze bush. There is a space perfect to take it with no machining needed. You can get it from Simply Bearings part no NTA-1625-TRA-1625 two washers and flat needle roller thrust bearing.

Hi Ian

Any chance that you could reassemble the Tailstock, and then mount a long series drill in the chuck, and drill through the barrel?

Once you have a pilot hole through, it could be gradually enlarged to just less than the smaller diameter of the MT taper, hopefully now by drilling from the back end.

Once that is done, you have a means of entering a drift to knock drill chucks etc out of the barrel.
