Speedie

I dont know if its the best but I have one from Integy that works great for me and it wasnt expensive.

I do for like maybe 20 seconds....

When reserrating a brush for the first time I break it in again for 120 seconds. But if Im only touching up the serrations between runs I do just like Eddieo and do it for a few seconds and check them to make sure they look even.

I believe Big Jim likes the Promatch one and the Integy brush serrator.

About brushes, how can you tell that they are in need of replacement but they still have plenty of length on them? Reason I ask is I have a pair of 767s in my Reedy Quad Mag motor and they haven't burned up, and have plenty of length on them, but they don't have the punch they used to have and I have tried truing the comm up. Big Jim says that they brushes will work even when they serrations are gone but I have read other places they work best with the Quad Mag when the serrations are there. Any Ideas?

Keep in mind, when you reserrate brushes, (especially ifyou do it serveral times) that A: they do get shorter...(I know..duh) but that cuases the springs to have less pressure on the brush that it did say, when the brush was at it's full length. That might be why you don't have the punch you originally had..your spring rate changed.

True.

I actually check my spring settings with my fiddlestick on a regular basis. Everytime I run the motor I pull it out to clean it up, and I recheck my FS settings so I don't think that could be the issue.

I don't however at this time reserrate my brushes. What all is needed to use the promatch tool?

I'm pretty sure all you need is an old motor.
