Thanks for sharing. 1. we shim the magnets, simply add tape behind the magnet to shim the slop out and pushes it closer to the arm for more power, and second they dont fall out. 2. we would clean the comm and brushes with pink eraser. then lube with Aurora red racing lube (very little, came in a 1 oz tiny jar, and its pretty thick), and oil the arm shaft, gears and shaft with ball bearing oil (zero issue of it getting on the comm). 3. You forgot to check pick up shoe wear and correct if necessary, and clean them with pink eraser.
I like your method. My eraser is white but is the same as pink. Much less aggressive. I rally cringe when I see videos where they use Dremel tools on armature and chassis. The tape on magnets is great.
@jettafixer7 the old white eraser for pens was much more abrasive, they now have less abrasive and softer white erasers. Balancing the arm on 2 razor blades really helped too. Regarding shimming the magnets, check the air gap, and then carefully modify the magnet or the chassis to make them as close as possible without touching, this really helps. Poor man's blueprinting, haha.
My white erasers are from Office Max, and they are pen type. The are very soft. I love poor man's tech :) I have never done the balancing. Do you have more info?
@@jettafixer7 use two razor blades, parallel and level so the arm shaft can sit on it and roll till the heavy spot settles at the bottom. With a dremel, remove weight from the bottom pole. Should be some videos on it, even if its not for slot car motors, the same principal applies.
I use a train transformer for break in. It is adjustable and works great. I have alligator clamps on the wires I clip to the shoes. Polish is not needed. A nice pencil eraser works awesome for cleaning armature.
@jettafixer7 The train transformer would be great. The polish is probably overkill but if I’ve got them apart I figure might as well clean them really well.
Circa 1965 I would modify a thunder. Jet chassis into a 4 wheel drive ! Just splice two gear trains together and flop second crown gear over...really raced FAST !!
I bet that really helped make it run better because I always needed more traction. I tried that but never had glue strong enough to hold the top plate together.
I will take the tube of polish and with just a little dab sticking out of the tube, I put the tube right on the armature commutator. This leaves a nice circular spot of polish. I use a cloth (I’ve even used a paper towel) and rub off the polish. I repeat until I get a shine. It make take two or three applications; one car in this batch took ten times to get it clean. It won’t matter exactly how you do it. Just smear a thin coating and rub it off.
When I was about 10 years old, the nice guy at the hobby shop showed me how to do all of this. I miss hobby shops!
There a few around and we need to buy our stuff from them when possible.

Can you please explain exactly how you polish the commutator with the simichrome polish? Thank you
Those are totally restorable.
Absolutely they are restorable. At this point I’m just looking for running chassis. Often I keep about half & sell off the ones I won’t use.
Personally, I'd be think able I'd be able to restore a number of those bodies back to factory minty-freshness-ness. I'm up for the challenge.
@jeffryan What’s your email?
I know you could do it.@@JeffRyan
@@jettafixer7 do tell.
