I like the idea about angle pinions for “During Race” tire changes or gear replacement (axle, tire and spur gear replacement in one complete switch). If the spur gear is setup optimally, it shouldn’t slip by the pinion and causes a slow “During Race” pitstop. A “During Race” repair isn’t the end of a race, it’s damage reduction. (GR)
@CleaveTech3 жыл бұрын
Hi Rick. Thank you for your comment. JK do not recommend angled pinions on their motors as this can produce a lateral force on the motor shaft pushing the commutator into the end bell. Many people have run angled pinions without a problem though 🤷♂️. I also like the ability to pull the gear and tyre off in one manoeuvre if a gear or tyre change is necessary. In the UK we have to run that gear ratio in the INTRO32 class so the angled gears are probably best.

its great idea to round the pinion corners and also the motor axle. makes less vibration...i recomend polishing the pinion teeth with dremel brass tools....cheers Rio / Brazil !
@CleaveTech3 жыл бұрын
I have seen people polish the leading edge of the pinion teeth but sometimes I have seen people do this too much and not have enough tooth engagement. I find that brushing the teeth by hand with a small wire brush after soldering is enough to remove any burrs but as you suggested, a brass wire brush in a Dremel shouldn’t be too abrasive. 👍🏻

Interesting. I am attempting to replace a worn alloy pinion with a new brass cog on my Hornby Ringfield motor. It is challenging as in this case it is an interference/machine fit. I tried immersing the brass cog in boiling water but as the axle is spring loaded, I couldn’t get enough pressure on the cog Maybe through heat transfer the heat might have been lost through the steel tools I was using to hold the cog

You could try cutting the gear nearly all the way through without damaging the shaft. You could probably then just break it off or pull it off.

@CleaveTech2 жыл бұрын
I used to think that a big soldering iron tip was necessary but when I started to realise that soldering is easy if you use the right flux and keep the soldering area clean, I was able to use smaller tips. It also helps to have a fast recovering iron. I think that larger tips are needed for soldering all brass chassis, but for flexi cars a 3.2mm or 5mm tip is fine.

I'm an old 1960's slot racer in the USA. Pinions are not press-fit now? I only ever had to solder one pinion, and that was on a Pittman motor with 1/8" diameter shaft that was to power a "rail job" drag car. Every other motor, most all Mabuchis, they pressed on. Back then Cox made a great pinion tool that would both press on and remove pinions.

Low powered slot cars still use press on pinions. The top level slot car motors nowadays have the shaft ground to 1.2mm and use 5t pinions!

Making sure there is minimal friction in the gears and axle will help coasting. You can also make sure you hold the trigger down when the power goes off as this will bypass the braking circuit on most controllers.

Thanks again, James. I'm guessing that you don't shorten the pinion, or at least by not as much, for inline classes to leave the possibility open to running different size contrate gears without needing to move the pinion?

How are you. I wanted to ask you a question about how to accentuate the brushes of the g12 motor, you can accentuate them in "cold" or natural water, or accentuate them with a chemical. ? I would like to know, to accentuate them and not spoil them. From already thank you very much. I am new. (I've been 10 years) in slot cars. I learn a lot from your videos. and as they say in this environment. I am putting together my little book. haha
@CleaveTech3 жыл бұрын
I have found with G12 motor brushes that they don’t need running in under water as the motors draw a lot more current as standard. I use a range of diamond hones to finish the brushes to a size that nearly matches the commutator, then I run the motor for approximately 40 minutes on 3.0V
@ronthornton25833 жыл бұрын
Why do you mount the pinion with the protruding collar facing the motor and not vice versa?
@CleaveTech3 жыл бұрын
Although I cut the pinion to save weight, the collar provides more surface area to solder to, giving a stronger solder joint. The collar is also a small diameter so it has less effect on rotating mass.
@saxmusicmail2 жыл бұрын
What is the reason for soldering the motor to the frame, rather than screws? Soldering would surely make motor changes very slow and difficult.
@CleaveTech2 жыл бұрын
Soldering the motor to the chassis helps keep the centre of gravity lower and reduces the overall weight compared to using a bracket and screws. Also some of the very smallest motors do not have screw holes and the windings of the armature are extremely close to the end of the motor.

How many RPM could you gain from cutting down the pinion?
@CleaveTech Жыл бұрын
Using a narrow pinion doesn’t necessarily gain RPM, it reduces rotating mass, which helps the motor spin up and slow down more quickly. That will make the car more responsive. It also lightens the overall car.
@harryw95982 жыл бұрын
cleave lovely job. did i hear it right is it a 1:32 scale? i do a bit of racing too. often i see the max rpm of the motors. are there any numbers of watt and torque? i know the old mabuchi motors are listed with torque. as for the pinion did you ever tried green loctite? you have to work fast and the fit must be not to wide. regards
@CleaveTech2 жыл бұрын
Yes, the chassis in the video is 1:32 scale. It is a Genesis chassis made by Richard Mack in the UK. It is the standard chassis for the British Slot Car Racing Association’s beginner class. These sort of motors don’t come with figures for torque or Watts. You could probably work it out by measuring the stall current. I have used loctite to glue on gears in the past but I find it can sometimes fail after a few months. Maybe it is the oil and cleaning fluids that attack the loctite?

@CleaveTech2 жыл бұрын
In the video you can see that I use an old motor to cut the pinion which is the process that causes the most metal dust. I only give the pinion a light skim when it is soldered onto the race motor. I also thoroughly clean the race motor after the pinion is soldered and located properly. This is also my own motor and car, not a customer’s car. I would always prepare a car for someone else to the same standards as my own.
