Love what you’re doing here. Been watching your videos, absolutely fascinated. Would love to see you make your own bearing from copper wire and balls. Not complaining, mind you, just wanting more of your components and even fewer made by machines.
Very interesting, from an engineering standpoint, I offer the following to hopefully support your thinking. I have a system thinking approach, I know in ALL systems entropy gets invited to the ''party' - e.g. your drive relies on friction, in your current concept that friction is not self adjusting, it will get to the point where it will fail, think gravity, allow it to maintain a constant force of the drive wheel against the bearing ring. quick concept might be to hinge the motor in such a way that a weighted arm (adjustable?) will always be ensuring the drive is pushed up against the bearing ring. I humbly submit this to your thoughts. Paul, Johannesburg
Thanks Paul. I think there will be a period of bedding in and then things will settle down. The rubber tyre on the drive wheel is not very soft and won’t wear down much. And the bearing will be fairly tight to the frame and should not move much either. I am planning to have the motor adjustable using a hex wrench under the cabinet, to allow for fine adjustment- if and of course when it’s required. Thanks again for the engineering advice. 🙏🙏

Cutting brass, copper, or even stainless tubing? Turn it with an electric drill while you're tightening the cutter. Saves your wrist if you're doing a lot.
Couldn’t you put the hanging points (I don’t know what to call them) of the big wheels in vertical slots to make it hang lower and then push it up with the small wheel, to let gravity handle the contact between the small wheel and the big wheel?
