This has got to be one of the best things I learnt to do a few years ago that made my cars so much faster and more consistent. I even do this when I am racing SlotIt, NSR, Scalextric, ScaleAuto and other models cars. You need a special tool, but there are quite a few available. Good quality grinding of axles and setting the tool up correctly is very important to getting the best results.
Here are some links to tools and equipment used in the video...

Hi CleaveTech - absolutely brilliant! As an old mechanical engineer from the sixties (yes, I am that old!), every bit of balance adjustment could make difference between a "win" or a "loss". A lot of our mods on the muscle cars of the era were done with "hands-on" work like you are demonstrating. Thank you for sharing your knowledge with a younger generation and a few older guys like me, Ciao, L (FoMoCo engineer, retired).

@modelracecar 2 года назад

I was so impressed I drew one up and printed one for myself. One thing I found is the ground points on the axle need to be dead centre.

@CleaveTech 2 года назад

Great job 👍🏻. The key things are to make sure you use a ceramic or glass surface at one end to reduce friction and, as you say, use an axle with very accurately ground points.

If it will balance those wobbly tires. I think you have a winner. As for those of us whom think the magnet might clock the axil. I would think the orientation of the flux should reduce or eliminate this issue (poles at the flats of disc). One could test for clocking by switching ends of axil.

To make your ho mega g pmus cars better and faster is literally gel claw tires if running plastic afx track especially if its a two lane with no room to slide and the car keeps de slottting unlike 4 lane where the car can slide and not debslot. I do everything in this video and man my ho cars are screaming now i just got a few tjey cars and a few especially the ford gt40 mkii short chassis mega g us car all these tips maxe that car stick better and not deslot as easy as it would when it was box stock that balancing device makrs a huge difference as well

@modelracecar 2 года назад

Hi James, I really enjoyed this video. Just a small point but the foam tyre you were balancing wasn't running true and would affect the balance.

@CleaveTech 2 года назад

Well spotted. You are totally right. It really shows up well on the camera. The tyre was not taken down to the correct size for racing so I would normally spot those sort of things on my final balance before racing, but I will investigate further as to why it appears out of true at this stage 👍🏻

@randywilson6536 2 года назад

Would you make a video on turning a analog car into a digital car ? Or am I going to have to turn my digital track into a analog track ? Thanks

@CleaveTech 2 года назад

I have raced digital a couple of times but I still prefer the “feeling” of an analogue setup. I totally understand how digital racing allows multiple people to race together on tracks that would otherwise not be possible to race on, but analogue cars seem so much more responsive and pure. I will definitely consider a video on digitising a track and cars though. Good idea 👍🏻

Where can I purchase this balancer?

@AlainJannuzzi Год назад

If you use a chamfered shaft on your car, the balancer shaft must be chamfered as well. Greetings from Brazil

@CleaveTech Год назад

Hi Alain. Are you referring to an axle with flats for the grub screws? If you are, then I totally agree. I need to do a short video on how to setup the balancer correctly and mention a few things about matching the axle to the one you use in the car.

@ACCOUNTANTB 5 месяцев назад

Shure it makes less vibration....but im not quite shure if this transmit to a real benefict..once the tires actually absorvs parts of this vibrations....if Motor RPM is so hi....bigger than 70K....shure it does a difference.Theres much things to consider besides only what vibrations does badly into it

@RVJimD Год назад

I have noticed that my balancer has a “heavy” side. This is with nothing mounted on the shaft, just the shaft by itself seeks to a specific spot. The friction is really low and the shaft will turn very freely but always stops in the same position. I have check the shaft and it is straight and true. The ground points at each end are fine. It simply seems as if there is enough magnetic field at work on the steel shaft that it pulls it to a north/south orientation. Has anyone else found this problem or come up with a solution? Thanks for any feedback. Jim

@CleaveTech Год назад

Hi Jim. I think if the friction is low enough the axle will always settle in one place no matter what you do. The density of the axle can even vary along its length which could cause one part of the axle to be heavier than another. If you spin the axle and can’t see it move and it spins for a long time then you have set your balancer up as well as you possibly can. The only other thing you could do is to reduce the magnet field by using weaker magnets or moving them further from the points but you then run the risk of not supporting the axle enough. Thanks for the excellent comment and watching the videos 👍🏻.

@slotsoffunwith1345 2 года назад

So I wasn't seeing things

@miners_treasures 6 месяцев назад

I never use hollow grub (set) screws because I feel it compromises reliability. Perhaps if I grind the bottom flat reliability would go up as to say it would not loosen off the axle during a race when tightening down.

@user-ju8po9sy2m Месяц назад

I've never had a problem with the hollow screws, even on stuff like group27 wing cars. The key is to use an axle with flat spots machined into them.

@miners_treasures Месяц назад

@user-ju8po9sy2m I prefer the completely round axles so I don't have to hunt the flats during a race.

@user-ju8po9sy2m Месяц назад

@miners_treasures that's understandable but if you tighten the screws enough so that they drag on the axle ahead of time it makes it easy to find the flats because the wheel or gear will get loose once the set screw is over the flat.

@Rafa_tm Год назад

What's the best way to grind an axle to get those precise sharp points?

Haha, if I told you how I achieved the super accurate points then people would not need to buy any of my balancers and axles 😉

@ronthornton2583 2 года назад

So what was the point of the colour coding on one end of the axle? I don't think you explained your reasoning ☺

@CleaveTech 2 года назад

The colour coding was for two reasons… 1) to make it easy to identify which axle size is which 2) so that you always use the same end of the axle when balancing to ensure consistency

@ronthornton2583 2 года назад

@@CleaveTech Thanks, that was my thinking too, but I just wanted to be sure.

@jameslewis5163 Год назад

I have a question True tire before balancing Or balance first

@CleaveTech Год назад

Good question. If I am preparing for a race, I would make sure the hubs are balanced fairly well before gluing on the tyres (balance achieved by shortening the set screw). Then I would glue and true the tyres to a size slightly larger than I think I would be using for the race. I would then balance them again using bits of tape but maybe not spend so much time getting them perfect at this stage. I could then try the tyres and practice with them. If I am going to use them for the race, I would then true them to the ideal size and rebalance them as good as I can get 👍🏻

@slotsoffunwith1345 2 года назад

@CleaveTech 2 года назад

@Carfunmostly 2 года назад

Why does there need to be a point on the end that isn't touching the glass?

@CleaveTech 2 года назад

It concentrates the magnetic field and allows that end of the axle to also spin true.

How much will this unit cost American money

@CleaveTech 2 года назад

I don’t have a final price yet but it will come with one axle of your choice (2mm, 3mm, 3/32” or 1/8”). Additional axles will obviously cost a little more.

Wouldn’t a grub screw in the opposite face serve the same purpose ?

@CleaveTech 2 года назад

Yes it would help the balance but can also cause the wheel/gear to run out of true as it can pivot on the two grub screws rather than be seated on the axle.

@InYourDreams-Andia 2 года назад

You did nothing for balancing..this whole video. To balance properly, add a counter weight opposite the heavy point. Like another grub screw etc. Shaving grub screws is too ridiculous.

@CleaveTech 2 года назад

Adding a counter weight is what I did to balance the hub and tyre assembly. Reducing rotating mass where possible has a positive effect on performance. Adding more weight is not what you want to do if it can be avoided. What is the point of having a grub screw that is longer than the thread it engages with?

@InYourDreams-Andia 2 года назад

@@CleaveTech car wheels IRL, digital balancing.. Finds the heavy spot (valve/tyre etc) then calculates the counter weight needed.. Places in exact spot. I thought you'd add a weight (or another grub screw oposite) before you start shaving. Tolerances are small, but clearly noticeable in your clever design. Your channel is great btw, as is your tech, fascinating stuff. 🤟

@CleaveTech 2 года назад

@@InYourDreams-Andia , thank you for watching and commenting. I suppose with real car wheels you can’t start removing material from the alloy wheels. I wouldn’t want to add another grub screw because that can cause the gear to pivot on the two grub screws and not run true.
