Brush Glaze
#18
I cut after every race day and normally run brushes for 2 weeks of racing(8-10 runs). After 2 weeks they have usually discoloured and are junk(I flatten them out and use them for hood alignments). If you run your motor for too long you'll kill the performance of the motor and it will take a crap load of cuts to get get the comm back to round.

I wish I had enough cash for a lathe

Thanks for the help.......
I took a picture of the 4499's I'm talking about. I got them to seat, but are they too discolored? Next to it is a 766 brush that has been through 4 runs, on a trued comm.

I've noticed with the dual shunt brushes, with more wire there is a greater chance of it getting hung on the edge of the hood and not letting the spring push the brush in further as it wears..
thus arcing more, getting hot faster and discoloring the brush like in the pic..
anyway just somthing to check...
