Default "Fixing" Scotchbrite Wheel

My 6" scotchbrite wheel has worked like a champ for my build but in that time I have developed two grooves in the disk from repeated deburring in the same place (ooops). Is there an effective way to "fix" the wheel to grind down the other area to get a smooth surface? It chews through things too quickly to adequately grind it down. Thoughts other than just live with it or buy a new one? The grooves are no more than 1/16" deep.

Debur some thick stock "on the flat" and vary your technique.

Buying a second one won't hurt anything except for your wallet.

Press on!

Course sand paper on a wood block, or run a die grinder with a course sanding drum against it.

Default The Fix

Take a broken grinding wheel or a rough rock and rub against the scotchbrite wheel to remove some of the wheels diameter and recondition the wheel surface

Default groovy is good!

I like the groove in the ScotchBrite wheel. It is perfect for deburring both sides of a piece in one pass. Just run the edge at a slight angle through the groove and each side of the groove will completely deburr the edge.

Here is the large groove that I cultivated on the 2" wheel:



It eventually gets even deeper (and works better) before I replace the wheel.

I leave the grooves in mine; it helps keep long parts on the wheel when deburring flange edges.

I like a nice pretty scotchbrite wheel. I keep one with certain depth grooves, and one flat and square. I use a large 8" angle sander with a super coarse grit (like 18 grit) paper on it to make wheel adjustments. Very quick and effective.

A Carborundum dressing stone will square it up quickly and easily.

I bought two, one for flat work and the other one for edge de burring as mentioned above.

I was able to redress my 6" Scotchbrite wheel on my bench grinder with an old expendable file. By the way, after the RV is now 99% complete the wheel is down to about 4.5" I used it for many, many parts.
