Are those sealed bearings on that arbor ? If not, you might want to think about a different arbor with sealed bearings. Just a little bit of grinding grit in a bearing can wipe it out in a big hurry. The bearings are one place you don't want to cut corners on cost. The 3/4" shaft should be plenty strong for what you have in mind. And it looks like the bearings are locked to the shaft with set screws. If you need more room for 2 wheels on the one end, you should be able to loosen the set screws and adjust the shaft as needed.

Say's so in the blue lettering in the picture of it. So I assume so.

You should be good to go then. Sorry, I was in a hurry, and didn't notice the blue lettering.

You might need to get a little creative in how you assemble this if you want more than 2 wheels. The wheels were meant to be mounted on the 1/2" diameter ends, so if you want to mount them on the 3/4" shaft instead you will need a bit more hardware. If you have access to a machine shop or are a machinist it should be no problem, but if you had that kind of equipment available you wouldn't need to buy it anyway.

Most wheels and expando drums have a 1" center, and come with shaft adapters. For a polish head, you might want to take your shaft to a machine shop to have the right end center drilled and tapped to 1/4" - 20 thread. This will allow you to use one of the many spin on discs that are available. You could also get one of the magnetic disks for the right end to use like a small flat lap.
