Starter Motor

[Bigbaldybloke]

Yep, no requirement to undercut the mica, needs a properly ground tool on the lathe, ideally diamond tipped but not essential. Any comm I’ve skimmed have all gone concave from wear from the brushes so need to be flat if fitting new brushes so they make good contact. If the comm is basically good and you are not fitting new brushes just polish up the comm so it’s nice and clean.

Thank you all for the good advice, I found GT Electrical (Auckland) who having been doing business for over 40 years and were more than happy to fully service the starter motor and only charged me the equivalent of 100 GBP incl Tax. bushes, bearings, lathe, clean, good $200NZ spent and should be good for another 50 years
