The wheel balancer from the 1960´s | How does it work? 

This is so ingenious, i really need to make one!

Ah yes, bring er back for round two. I think this machine is probably one of the coolest little pieces of mechanical history!

If you place the machine on a 4-spring rocker and only allow the dynamic balancing axis to move, an unbalance at right angles to the rolling direction will result in pendulum movements. This can be easily seen with a dial gauge. To do this, however, the rocker must be exactly balanced with the wheel mounted and measured with a spirit level. Of course, this also applies to machines without a mounted wheel, but with the wheel's mounting disc. The motor may have an incorrect mains voltage that is too low and would have to be rewound to the current voltage. However, it is also possible to adjust the voltage with a 3-phase transformer. If you can also find a rotating frequency converter with a DC link as a motor-generator converter, you have everything in original analogue classic permanent quality. If the machine is set up correctly exactly to the direction of rotation of the earth with the axle, the dynamic balancing can also be concluded from the difference between clockwise and anti-clockwise rotation due to the Coriolis forces. This is what the direction of rotation switch is for. Thank you for the very nice video. EISENEXE

In my experience, most garages these days will not balance correctly, with so called new equipment, with steering wheel wobble happening. It took me many many experiences to find somewhere that accurately balances wheels. This old machine proves that occams razor, aka the simplest theory will often be true. Thanks for the video and your passion on explaining !

This machine is so cool. Old fashioned engineering with no electronics. I think the reason the shaft only needs to move from side to side is because the wheel is spinning, so all side to side positions relative to any point on the circumference of the wheel are accounted for.

What a shame you forgot to Static Balance first. Nevermind, I'm sure it will be a success. What a cool machine.

A great machine! The little pattern it made reminded me of the Spirograph design toy! Can't wait to see the outcome next week!

Something new every day! Thanks!

It’s interesting how the oscillations can increase as the spindle slows. I guess it must be passing through the resonate rotational speed (frequency) for the imbalance under test. The L&R horizontal axis displacements resulting in the cardioid pattern. Very clever indeed.🍻

I love these kind of videos

Fascinating stuff.

Very instructional and well explained making it interesting

There was a very simular one in a garage I worked in in the 90s it wasnt used anymore but it was still there..

Very interesting thanks

Simple but effective.

Sometime the simple solution is the best.

That is a great and simple machine. Ingenious. Leave it to the Germans to come up with it. I can't wait to see you test it with the new tires. Thanks for showing it to us. PS: do they still make that machine?

It's the science of wobbles, I'm sure there's an actually smart sounding name for that, but, the science of wobbles sounds more fun and interesting... :D

A simple robust machine! A modern tyre balancer will not last anywhere near 60 years or more like his one has and will.
