in the "old days" we used to use all sort of concoctions to clean comms. Nylon brush between races, copper polish on a bit of leather with the comm spinning in a drill (ore-Dremel), hell I even used wet & dry!

Com sticks with stock, always after EVERY run, then a flush through with motor cleaner, never ever wore a com out when racing. The magnets would go soft before the comm got anywhere near looking like it was worn out....

I used to use a bit of Brasso on a cotton bud, scares me now to think what it would be like without lathe's. :D

so we darw a conclusion of any diy or house hold cleaner products for cleaning the com,nice one guys,so at the mo i am using a very old skimmer,infact it's a grinder ,you put your com in the holder and attach an over large pinion on the end which in turn a belt goes from the pinion to the 540 motor the holder is on a slide left to right and the other end of the armature sits into a bearing holder ,then the turn of a small wheel will move the armature ,back and forth to a grinding wheel with very fine emery cloth on it,it takes quite a while to re-grind the com but it does not do a bad job,could this be one of the first motor lathe's ???
