I just took an angle grinder with a 36 grit flap disk. Did NOT turn on the buffer motor. The angle grinder caused the scotch wheel to spin on its own. Made quick work of dressing the wheel acceptably clean and even. Surprised me. 🙂
Well, every time you do it, all the dust is that expensive wheel going away, so as little as possible. In the video I took maybe 3/32” off of the highest part tapering to nothing on the lowest. I assume your question is more about what the useful limit is?? We replace them when they are about 3”. It’s the surface speed loss that really is the catalyst. When they get small you can use them in a drill press for rub lightening holes.
Yea!! The videos are coming back! Nice to meet you in OSH.

Great advice! Had to share....
Some safety tips: use gloves and glasses, use a clamp to attachh the sandpaper to the piece of wood
Gloves and rotary tools don't mix.
@@garrettwirka2522 your hands, your rules ;-)
How many times can you do this before the wheel is worn down too much?

@@mikelauritsen553 sounds good. It's nice to know, because those wheels are pretty dang pricey.

I've had mine for years but just light use hobby work.
