We used the Ideal comutator stones for years on the railroad locomotives. Especially on the older fuel pumps until they went to brushless pumps. I can't tell you how often I was able to get a stranded train running again with just a quick clean up with these stones and a fresh set of brushes. Keep up the good reviews.
I have always used pencil erasers. I should have known there was a proper tool and Catus Maximus would have one. "Back in the Korean war we would disassemble our motors and rewind the armatures in the field..."
@@stinkycheese804 If it is leaving grit behind you are doing it so very wrong. You just ever so lightly touch it to the motor and clean methodically. You do not shove it full force on there like a cheese grater. If you see dust behind use something they invented called an AIR COMPRESSOR. And if you still want it clean, get a dialectric spray cleaner for electric motors. There is always a danger in doing something when you have no idea how to use tools properly.
@@huskyvacs It is absurd to use a stone if you don't have to, and there is no need to make a mess (which it will do, it necessarily leaves grit behind to whatever extent it does the work) then have to clean it up. This method puts more wear on it as well. There's doing a job and then there's doing it right.

Man I didn’t know that was a thing. Probably will be awhile before I’ll need to clean any commutators though.
Work e like magic 💯💯
It cleaned the commutator and seared my brushes with ease no more sparking
Brilliant! Thank you!
Were can I get the stones
Amazon
I've just used 150 grit sandpaper.
Me too, except finer grit. I would never take one of those stones and use it on a running motor because of all the abrasive grit it leaves behind.
garnet paper might be a better non-conductive choice...

Where can i buy one. Great video 👍
ebay has them, from $10.00 up to $75.00 for a single stone of different types. Also Grainger has them too.
One chunck of this thing can break a brush, I've had it happen.take the motor apart and do it the right way .
