Anyone have any recommendations on how to dress a scotchbrite wheel mounted on a bench grinder? Im starting to get a bunch of gouges on the outer edge of mine as I work through cleaning up stiffeners and such. I had a dressing tool that came with the grider but the stupid scotchbrite wheel keeps winning the battle with it.

i've wondered the same thing. seems like the grinding wheel will grind anything, then take the grinding wheel and put it on a scotchbrite wheel, voila grinding wheel gets gouged! no, i haven't tried this, but scotchbrite is one tough piece of material!!
I have a cheap grinder from Harbor Freight. I took one of the blue grinding wheels that came with it and used the flat side to dress the wheel. In 5 min or so Ican make the scotchbrite wheel flat again.
I have tried an old file and an old chisel with partial success. The wheel came out better than it was, but not nearly as good as when new. Also, I have several scothbrite wheels in various diameters, and it seems that none of them were perfectly round, or had perfectly centered holes, when new.
Well, I googled for this and it seems 3M makes a dressing tool for Scotchbrite wheels, but I don't know who might distribute them.

Spike,
I came across a post from someone at Cleaveland Tool that recommended using 40-grit aluminum oxide sandpaper to dress out a scotchbrite wheel. I got some of that, adhesive-backed, and put it on a small piece of 2x4. Seems to work ok, but it will make a mess...and a respirator is manadatory!

I use one of the smaller scotchbrite wheels on an angle die grinder and spin them in oposite directions against each other. It smooths them both out at the same time.
They make dressing stones to dress aluminum oxide and other types of grinding wheels. Our experience is that they work very well on the scotchbrite wheels and are very inexpensive, i.e., $7.50 range.
