How To Square Wheel Grinder accessory question.

I bought an Olympic Foundry square wheel grinder from an estate last year, and while it's a great machine, I got two accessories with it that weren't really expected.

The first is this picture is a tight corner air bearing platten (or at least, that's the name I've given it, but could certainly be wrong). When this is installed, and connected to higher pressure air from my compressor, I can run a really tight corner across it. It's a pretty cool setup, even if I don't really use it.

The second accessory I haven't been able to figure out yet, and hope someone here has some ideas. I'm assuming that it's both of those parts, the arm/fiber wheel assembly, and then that idler wheel. It makes sense where the arm/wheel would replace the standard rest on my machine, but I'm not sure how the wheel is driven, nor how that idler wheel would attach/work.


Any ideas on that would be helpful. Thanks!

Congratulations on your square wheel grinder. I have used one for 40 years. It is a real work horse.
Without more pictures I can't help you with your question.

Tom, please leave offers to buy/sellout of Shop Talk. Use PM, email, message, etc. - Moderator

More pictures from grinder maybe would help us to figure what is what . I assume that felt/fiber wheel gets drive from that rubber wheel with belt over it ?

Or a rubber/fabric drive belt with no grit.
 
The ID of the idler wheels bracket is 1.75", a size I see no where else on the machine. I'm not presuming that I have all the parts to make it work, even at that, I'm still too dumb to figure out how it'd work. Like Natlek suggested, I thought that maybe there was a belt that would drive the idler, and the idler would friction drive the fiber wheel, but I'm still not seeing how it'd set up. The direction the fiber wheel would spin would make me pause, though.

I've included some more photos of it all, including the tight corner fixture. I think something like this wouldn't be terribly hard to recreate if someone felt the need. I'd guess most guys would just do it by setting up a collar on bearings, but since this came with my machine, I'm glad I don't have to do anything but install it and run.
