Hi John I have a question for you. I recently purchased a pair of your sport motors for my truck. they are awesome and put out an impressive amount of power and control for the value. After about 6 runs I"m hearing an odd clicking sound from the rear motor. It is very apparent going foward but not really when I reverse. I took the pulled the brushes and they look pretty beat. There is a large pile of brush material on the trailing edges of the brushes. They look pretty pitted and have chipped looking edges. The comm looks pretty good no gouges or heavy scoring. The end bell has no scratches on it so im pretty sure the hoods didn't get smacked on the rocks causing misalignment. Could you help me figure out my problem please. Here are a couple pics of the brushes |

Okay so Eddie O got me taken care of and helped me find my problem. What a stand up guy. He helped me with my motor regardless of the fact it was from his direct competition. And no his answer was not to buy his motors. Thanks once again Eddie for your help when I could not get it from anyone else.

I've seen chipping like that before when I used really high spring rates. Or it was coincidental with whatever the problem actually was. But it was around that time that I went to a medium rate spring for the various 35 turn motors in the Losi, all the while being comm cut compulsive, and haven't had the chipping issue since then.

On its own, spring tension won't cause stuff like that, it however can and usually always will amplify another issue......so if you have a badly pitted comm slot........super stiff springs are BAD news. Later EddieO Quote:

Fairly cheap BRAND NEW comm lathes..... http://cgi.ebay.com/iNTEGY-MOD-Fashi...item2565bf9c59 Found them while looking for one for myself. Not sure how good they are, but the price is low. I'm trying to get a Hudy, but looking at a few other used ones. Mostly a couple of Hudy's, Xip, Orion, Cobras,..... |

Decent little lathe once you get it setup and such, remember though, it doesn't come with a motor for that price. I've got a spare Hudy if yer looking for one Later EddieO |

I'm not fond of the bearing supported mini lathes. They get sloppy pretty quick, and knowing integy they are probably sloppy from the box. Give me V blocks any day.

I would think new bearings, some shielding and constant maintenance would yield a better cut. But if you slack on any of it, you can get hurt real fast/real quick. | |

V block with the arm riding on a film of oil is maintenance free, if you don't forget to add the drop of oil. And wipe the V block area clean every time before you add the drop of oil. Hmmm, how many moving parts in a bearing? Compared to how many moving parts in a V block? |

I am a vblock guy myself, but there are thousands of the bearing supported units out there and they work fine.........with the amount of use crawler guys use their lathes, bearings should last just fine. Later EddieO |

The bearing slop just bugs me, I hate anything that contributes to chatter. I agree that most people won't use their lathe enough to wear out the bearings though, so when it boils down to it it would be just fine.

Biggest gripe I have about a bearing type is it will let a shaving to go between the bearing and the motor shaft. That will cause a jump and a gouge in the comm. V-blocks really don't have the room for shavings to get in.

I agree.....I would definitely upgrade the integy bearings to a nicer sealed unit that has been cleaned out good and oiled... Later EddieO |
