Painted, mounted, and tested with the new belt I picked up on my way home tonight. Ran it wide open for 10 minutes in each direction and the bearings barely got warm to the touch after being cleaned up and lubed with dry moly spray. What I expected to be a $150 project has cost me $10 so far. It seems like God has provided what I've needed so far (including the advice from you guys), so I'm holding off on spending the $83 for a disc from Rob. We'll see what turns up in the next week or 2. If I don't find a disc either cheap or free I don't think spending the 83 bucks will break me, but I'm cheap enough to wait and see!

That's a very nice job! I've heard of people getting discs from Grizzly (cheap chinese made), but having 4 of Rob's discs on grinders, I'll have to say that they are very very nice pieces of equipment that you won't regret getting.

I have a $15 9" aluminum disk mounted on an axel. It's garbage and flexes when I put too much pressure on it. I plan to replace it after I build a belt grinder.

Spend the money and get a proper disk, if you can. You'll be much happier...:)

What did your bearing/axel gizmo come out of? Is it salvaged? I like it!

It came out of a blower that was scrapped a few years ago at my workplace. I'd planned on using it on a BIG rock tumbler, but I sort of lost interest in the concept.
 
Mark, I ordered my disk from Harbor Frieght parts, it was $9. It's aluminum and the shaft is drill all the way through. I believe Rob's disks are completely flat and cover the shaft. Anyways, thought I'd mention it.

Thanks, I'll look into it. I'm considering making my own, but I'm not sure I can even buy a 12x12 piece of 1/4" plate stock for less than that.

I suspect that I smell a hint of wisdom in that advice. I think I'll try my hand at making one from 1/4" plate stock, and if it's not quite up to snuff it'll be relegated to low speed work mounted on my 170 RPM gearmotor after I buy one of Rob's. Somebody sent me a private message and suggested the plate stock. As I was reading it I suddenly realized that I already have the hub in the form of the coupler that was on the end of that old blower shaft...
 
Hi Mark, congrats on a very nice job. I will also suggest that you consider Rob's disc. The bevel is a very good feature, and like everything else he makes, it is precision and like tank tough!
Best wishes,
Don
 
About 20 years ago I needed to adapt a brand new 20" shaft outboard motor to my beat-up old tub of a fishing boat with its 15" transom. I sandwiched a length of pressure treated 2x6 between 2 pieces of 1/4" plate aluminum to make a rudimentary jack plate and bolted it to the transom. Served me very well until about 5 years later when I bought a new boat with a 20" transom. I still have one of those plates of aluminum. It measures about 9.25" x 12". No matter which way I cut it I'm going to have to include 2 of the holes that I drilled in it, but that's easy enough to fix by press-fitting a couple pieces of aluminum rod in the holes before I have my buddy the mill-hand surface and taper it.

I know... Buy the disc from Rob. But folks, I GOTTA try this!
