I rember a quick shot of "liquid wrench" had almost the same result as using com drops. I found the overall life of the motor was shortened dramatically when using either.

Here's another trick. Take the motor apart and put a dap of toothpaste on the bushings (stock motor) . Put the armature back in and chuck in a dremel. Spin the arm while working it back and forth for a minute or so. This smoothes and polishes the bushings and armature. Clean out the toothpaste and reassemble the motor. Lube it up with bearing or bushing oil. Makes the bushings have less resistance and spin more freely.

Yup, Paragon made them. I still have a NIP one.

I remember using the Paragon kit. It had a small hollow metal end that you would lay down into the commutator area. It did work for a little bit, if you could get the thing to stay in place...

Trinity "Black Death" ... looks like carbon suspended in oil

Fantom 2002 drops seems to have all evaporated

Plain water dripped onto comm didn't do too badly either... try custom ice cubes...

anybody bothered to reverse-eng TRIBO POWER MATRIX?

i swear it smells like some types of Auto Tranny Fluid...

RIP Big Jim!

yep RiP Jim... Quite a character!

I have some Tribo that I still use - I never found it to bring additional perf but it SURE helps with brush lifetime. Every time I rebuild a fresh brushed mill I lightly scratch the brush contact surface with an xacto (if the brush isn't serrated of course) then I put one tiny drop of tribo on the brush, which I try to keep vertical (use a third hand for this, or even the shunt as it's rigid enough if the brush is already mounted on the head). After about 15mn the tribo has soaked in with gravity - et voila, the brush will last twice the amount of time. This basically provides extra lube to the brush coumpound, so it takes more time to burn it (discoloration).

Another use of tribo is to soak bushings in it, heat it up (you can use a beer bottle cap for that, just remove the plastic insert and lay it on a soldering iron)... after a few moments you'll see bubbles coming out of the bushing, that's the air that gets out of the porosities, then oil goes in, et voila, lubed bushing forever...

I was also told tribo was tranny fluid... I guess we'll never know. Sure was good for all this voodoo brushed motor stuff

As far as regular perf-boosting comm drops, I always found out that the dirt the comm picked up because of them never offset the benefits of these hypothetical few incremental early rpms...

Feels good to talk brushed motors! They have such a different feel to the soul-less BL's I use on my racers now...
