Thanks Matthew, Never come across armature chucks before.
Just to prove I over think my projects as well. I put the bushes in oil, microwaved* it to heat it up a little then ran it though a few cycles in my vacuum chamber. Seems to have worked lol

*in hindsight I'm not sure that was such a good idea. Still it heated up so I guess it worked.

Well I used the 32, fingers crossed.
Made a puller for the large end.
Pulled the bushes and replaced(I was right the, small bush did grip the needlessly accurate puller, but lots of little taps got it out without moving the bush).
Put it back together. Pretty happy, is running better than it used to(it was always slower than the other motor but seems about the same now)
I'll just have to keep an eye on the brushes as they dont seem to have 100% contact. Maybe they just need some running in?
Thanks guys

Hi Stuart,
Always good to see a project finished.. did you run it with lots of end float to find the magnetic center?

Hi Ray,
Yes and no . I put it back together as it was and tested it. It starts and stops with the brushes off the end of the commutator, when running it pulls the commutator back. I should have made a spacer......it seems I forget.......... I'll get onto it.
