Secrets of Slot Car Racing #7 - Rescue vintage Aurora Thunder Jet slot cars 

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!

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.

nice video! thanks for the share!

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.

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 !!

Those are totally restorable.

Can you please explain exactly how you polish the commutator with the simichrome polish? Thank you
