The tailstock on my Harrison M300 was badly bell mouthed, so over the last 5 nights I've been boring the tailstock out to take a 50mm phosphor bronze sleeve.
The base had been hand scrapped in by Slideway Services, and was parallel to the bed, so if I wanted machine a taper then the top will still be on the same axis.
I was lucky in that a mate had given me a 350x25mm Sandvik insert boring bar a while back. So this was chucked up in a 200mm 4jaw chuck. I've never done this before so a Little head scratching and it was setup.
The close up is after a few passes, taking almost bang on 23 minutes (need snoring doofer) for one pass at 180rpm
