I agree with the above reply. You can soon modify oversized brushes by rubbing them on a sheet of medium grade 'wet and dry'. Just remember to use the old springs from the projector with any modified brushes. The only other point worth mentioning - motor brushes can be manufactured from many grades of graphite, grades run from soft through hard and some types can contain metallic additives. The grade is not a problem in a low use motor; however, using a hard grade on a well worn commutator will produce sparking for a long time, as the brushes will probably never bed in properly. |
