This was just to be a proof of concept, but it seems to work well enough as is to get through 12 rims. That being said, if anyone has an 5 lug upright and hub just sitting around I could borrow, I'd take gladly take it!

HF Bench Grinder with Kustom PVC pulley
HF 8 inch wheel to act as the hub
Bicycle inner tube for a belt
5/8" all thread for a spindle
3" wood screws for added hilarity

Caltech, but who's counting. I think if I was on the other side of the screen I'd think myself nuts.

Cool. This rig could also be used to check the rims for dents and other abnormalities.

Let's see if I can ruin that guys computer again...

Notice the 3/16" or so of run out. This is what happens when you build a 5x130 hub out of a wagon wheel.

So jack the front of your car up, remove the wheel, put on the one you want to polish w/ your rig sitting on the floor below it= VIOLA!

I would like to polish the propeller hub on my 150. someone suggested I do it with the engine running. (IMG:style_emoticons/default/av-943.gif) I declined their suggestion quite quickly. (IMG:style_emoticons/default/lol-2.gif)

Elliot,

I would be happy to let you use my top of the line polishing system for the hub. If you want to build one yourself, my licensing fees are very reasonable.

Someone either here or on FB posted a pic of a wheel polishing rig that involved putting the car into gear with one corner up in the air and the motor running. I think that counts as more ghetto due to the greater potential for damage if the whole car moves than if just the wheel/hub does...

Thanks. Maybe I'll just polish it with the engine running. (IMG:style_emoticons/default/av-943.gif)

Now add an adjustable, spring-loaded arm to hold the sandpaper for you. Then you can just let it run while you drink coffee.

That was me... I wanted to be able to do it at night, under a canopy, and have it be quieter.

We spent some time in Adobe Illustrator, made a template and then redrilled. We also used some of the wheel weights we use for the karts to statically balance the hub. The shakes are gone and I'm on my way.

Not a bad idea but your back is going to hurt when you are 60.
Bowling Ball Refinishers make $38,000. Per year! Where a dust mask and wear eye protection.
