High Ratio CVT Model 

I have a german drill press from 1949 with such a CVT. Goes from 400 to 4000 RPM. I love it!

nice to see a vid from you Cosmas .... thought you had done one and dissapeared like Jer Schmidt did for a while ... life n all that... peace

CVT transmissions can be found on just about every automatic scooter. All the manufacturers use the same system. The gearing change is achieved by the increase in engine speed activating a set of rollers that adjust the position of one of the pulley faces along the shaft using centrifugal force.

more videos :D thank you

does CVT have even make sense with rubber belts? Doesn't it wear too fast?

The Shopsmith uses a single belt version on the Mark V

Do you think you could use 3d printing for the final product? I mean there are some pretty tough filaments nowdays?

Fantastic! and it is not Toyota CVT problems or Nissan CVT problems or…

Any excellent demonstration. There are already drill presses that use this mechanism. Look for a scheppach dp19 vario.

Cool

The application of CVT are potentially many. However engineers often seem to choose other solutions. Probably they have good reasons. I suspect energy efficiency might be low due to high friction? Very nice setup by the way.

That would be an epic project. Then, if you're happy with how it functions, maybe consider selling the plans or conversion kits for various types of drill presses.

I want one on my bicycle 👍

Thanks for sharing. Never seen the concept before but I really like it and see that it’s exactly what ytou need!

Can even search Reeves Drive Nice model, very smooth. Planning on the same for my drill presses Thanks for sharing Cheers

This is incredible!

Almost as exciting as watching paint dry.

Loved it, but do not understand why it isn't used for drillpresses😍

Nothing new. The car manufacturer DAF had made a car with such an engine/transmission. But thanks for the video, so the priciple is to see very good.
