Auto wheel spinner

The main and only real bugbear with my Tesla EV is the super low profile tyres barely protrude out past the rims so it's dead easy to rub the wheel rims up against kerbs.

I even managed to mark a rim when leaving the delivery centre when I picked up the new vehicle.
After driving just 12,000 k's I managed to mark all the rims, with the one shown below being the worst as I had managed to mark it almost all the way around (see purple and red dots). I'm doing better these as I get used to the car as I have only marked one in the last 6000 km.

There are people that will come around to your place and charge $250 :oo:! per wheel to repair them.
The matching metallic paint costs $20 for a small bottle containing a small brush, or $35 for a spray can so when it came time to rotate the tires my BIL and I decided to repair the damaged rims ourselves. (BIL and two other brothers also have Teslas, one brother has an MG electric and a sister in law has a Fiat electric)
We tried repairing the rims while they were on the car but it was not easy with the wheels so low to the ground.
Sanding out the scratches was easier when the wheel was off the car (ie horizontal) but spray painting still not easy, it would be easier if teh can could be kept upright and the wheel is spun, so my BIL and I decided etc make a wheel spinner.

The plan was to make an ally stand with a studded wheel hub so's the wheel could sit vertically and be spun while spray painting the rim edge and this is what we came up with.
BIl is an ally welder and he knocked up the frame in short order - the right angles of the vertical are made of 80x80x5 mm AHA ally, such that removing one of the bolts allows the stand to fold up.

I turned up the hub plates from two discs of 25 and 16 mm thick Al plate.
The 25 mm has a chunky 72 x 19mm bearing buried inside it, while the 16 mm thick plate contains the 5 wheel studs, with the two plates separated by a short 45mm diam Al rod that acts as a sort of axle.
An M12 bolt passes thru the stud plate and through the axle to a large washer that rides on back of the inner bearing race.

High precision was not needed as the rim will be spun by hand at
