Clogged Sanding Drum

I've got one of those 1/2" round metal sanding drums with the tungsten carbide grit for my dremmel tool. It's clogged up from grinding bits of epoxy or something. Any tip on how to get it clean? I think I paid pretty good for this thing. I was thinking about burning it off with my torch or maybe soak in acid?

I've had good results, using a brass brush while the drum is running at low rpm.

You can burn the clogged stuff off. I just use the kitchen stove burner for convience. If you have epoxy on it it will smell bad and is probably toxic. Use the exhaust fan and make sure the wife is not at home. I believe the grits are brazed onto the substrate. BTW, remove the inner rubber drum before you do this, it smells worse.

I have an old aerogloss 4 oz jar full of acetone that I soak things in. Worked so far.

Giffy,

Try sanding some scrap Plexiglas with it. Rubber from tire or shoe also works but much messier.

if there's rubber, that needs to be removed, but I drop clogged metal things into my bucket of chem dip for carbs. Works really great.

Good question! I did a similar thing, with a couple of small-diameter grinding thingies (technical term), by trying to grind aluminum. Now they're all smooth because they're filled with aluminum. I have no idea how or if I can get the alum. off...

Aluminium can be taken off with the stone that comes with the dremel tool...if you dont have one, get a small grinding stone from a hardware store and run them against it....works a treat.

Or you can try soaking it in Red Devil Lye.. It'll dissolve the aluminum (want to do it outdoors - it releases hydrogen) but it shouldn't touch the steel or carbide.

Hmmm. I should do this myself - I've got one I clogged up years and years ago, if I can only find it..

ethylene glycol does the same thing...a bit of brake fluid works ........but definatley do it outside....
