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
I loved seeing this machine work the first time i saw it. Not suprised that it's super popular on youtube. Everybody's grandparents used to need a machine pretty much exactly like this so their cars would run right. Its like you have a little peace of what life was like back before computers were used for everything. Pure nostalgia bate 10/10 👍
We had one of these balancers in our seaside garage in Devon, through the 1960s. It took at least 20 minutes per wheel. You always added the static weight last.
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.
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.🍻
As I rememer I wasonce told they stopped using this style of maching because they reuired sunch a high wheel speed to work properly that it was pretty dangerous tu use.
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

Ah yes, bring er back for round two. I think this machine is probably one of the coolest little pieces of mechanical history!
Works much better than modern machines, judging by my walmart balancing experiences.

Something new every day! Thanks!
This is so ingenious, i really need to make one!
A great machine! The little pattern it made reminded me of the Spirograph design toy! Can't wait to see the outcome next week!
Fascinating stuff.
Very instructional and well explained making it interesting
I love these kind of videos
There was a very simular one in a garage I worked in in the 90s it wasnt used anymore but it was still there..

What a shame you forgot to Static Balance first. Nevermind, I'm sure it will be a success.
What a cool machine.
Very interesting thanks
Simple but effective.
Sometime the simple solution is the best.

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