Cool, I have a nip 27t axial silver can I'm going to run it with and a converted atx power supply with 3.3v. I also added taps for 5v and 12v so I'm good to go with that I think.

Got busy before After, I think this was 3 cuts, wasnt satisfied yet with this. I think the bit was a little dull and shimmed to high?? Seemed a bit too glossy but idk. Moved onto an arm that needed more work Put a new bit in and shimmed it closest to center without going below as I could see and went at this one with 5 passes, half knotch at a time. Seems pretty good to me? Thoughts on what this looks like, is it right? |

| Re: Cutting a motor commutator & motor tweaks +1. Last comm looks the best to me from the pictures. Don't forget to clean out the comm segment slots when done, I usually drag the back side of an Xacto knife through the comm slot, that will clean out the copper bits & also help prevent comm shorting. PS, I used to run a ballpoint pen down the comm slot to "break" the comm edges, I just do the knife scrape now. Performance seems the same. |

| Re: Cutting a motor commutator & motor tweaks
Just wire this up and am a little suprised at how hard it is to cut serrations using this. I have the 45t rc4wd motor runninh at 5.5v and I have to push quite hard to get any grooving happening. The only way I could get it to work was to set the seration bit hit even so that I could flip the brush upside down and right side up while cutting to get an even seration. I had to puch pretty hard and it took a good 5-7 minutes to cut in deap enough to do anything. Just seems like I should be able to place them in and it would cut like butter looking at the bit but that just not the case. Tryed running it on 3.5v, 12.6v and reversed direction and didn't make alot of difference either way. This was bought new for 7 bucks so no worries if it is crap but it is nip from integy so I don't think the bit is dull. Anyone have experience with this xipp brush master, whats the best way to properly use this tool, no instructions included? Thanks |

Use thread cutting fluid from the hardware store....makes them cut easier and faster,while being a better cut too. Later EddieO |

Whatever brush cutter I have, can't remember and it's not the same as yours, sucks also. I got a Fussy from Brood and that thing tears em up, in a good way. However I still use the powered one more. I figured out if I don't use the grooves intended to hold the brushes but lay it on the deck and freehand it all it's way faster. Still takes pressure and a flip over but it's a done job in 20 seconds. My bit seems higher up so I'm able to. Or the deck height is thinner. Maybe not though, as I need to flip the brush over to do the full face. They look fine though different because the serrations aren't from edge to edge. The Fussy has numerous bits to replicate the diameter of the comm. Bonus. |

I'd move the bit so it get half the face of the brush. Hit it and flip it and hit it. Move it around a little. Much quicker.

| Re: Cutting a motor commutator & motor tweaks
Thanks, your cutter looks like it serrates nicer than mine, this bit makes the serrations really coarse compared to yours, bit is way different than mine. I'll try again using cutting oil and your trick EeePee, that will allow me to get into the sides better. I just dont like the way it is leaving the brush face in the pictures, wonder if I could find a better bit to use with it? Also what is the ideal voltage and drive motor or even rpm to run the cutter at?
