Many years ago, out on one of the ships, I built a grill from a 42gal oil barrel, I used a standard straight-wire cup wheel to clean some spots where I needed to weld, and it was fine as long as I didn't bear down hard. I sneezed at one point and jammed the angle grinder into the barrel and it tore up the surface. Had I been using a knotted/braided cup, it probably would have gouged right through the barrel.

Hmmm.... the weed burner and my drill mounted wire wheel is sounding better. I may try the flexible sanding disc as well.
