Great tool for drum brake cam mod
Posted: Wed Dec 28, 2011 2:25 amAfter searching all around town for a 1/2" wide grinding wheel with no success.. i picked one of these up at Harbor Freight for $30:

It's a bit on the pice-of-junk-quality side and i dont expect it to last for very long, but it made extremely easy work of putting the radiuses on the stock drum brake cams. This job would have taken 7 years with a hand file.. and i think it came out even better than i could have done with a bench grinder, even if i found that narrow grinding wheel that i was looking for. Anyway, it's worth a shot if you were as stumped as i was by how to efficiently do this job. They make an air-powered version as well (but that one looked even more junky than the electric!)
