This is great William, I had the same problem with a taper pin breaking, I used another taper pin and gently tapped the broken pin out with a small hammer, I did forget which was the smaller diameter side so kept tapping at both sides until I got some movement.
I am envious of your bushing machine, I will treat myself one day if I can stop myself from buying clocks.
This is great and I look forward to the next episode 
Paul.
