    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    Thanks for the inputs. Yes, I’m still working in the final drawings. About pinion installation, it is always pressed with tools like that below. Balancing the pinion would be good but by far is not a so rewarding job then making sure all chassis are well aligned, but ok, it’s always something...

    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    Thanks. Madlya is a brazilian company that sells armature dynamic balancers, maybe I will try it at some point. But my main focus with this topic would be to discuss the specifications of this new pinion and the best fabrication procedure for a very good precision. Watchmaker lathes and MIM...

    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    Walt: how can I perform a high speed balance with these tiny Brushed Sealed DC motors??

    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    Thanks Walt. Your appointments are absolutely right. Serious racers work hard in the alignment of the chassis with rear and front axle, besides the car body too. All the screws are tightened and loctite. Static wheel balancers are used and the foam tires are trued in small tire truers made...

    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    Hi Tmoose, thanks for the reply! Yes, the motor shaft and axle are slightly angled each other. It’s a “Anglewinder” positioning and I really don’t know for aure why a lot of slot car preps use this way. The other ways are “Sidewinder” (100% parallel - the way you should have suggested) and...

    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    Here are some photos I was thinking about making some holes in the face to reduce weight. This is a type of grease used to lubricate the small (pinion) and big (nylon) spur gears.

    Super lightweight and low friction Pinion Spur Gear Design for high performance slot car racing

    I would like to develop a new pinion for DC motors used in slot car racing competitions. The objective is to make a state-of-art pinion, focusing: - high precision with lowest friction possible when used together with currently available nylon spur gears/crown gears; - much lower weight than...
