Hand Grinders, Danger Will Robinson!!

Recommended Posts

I finally gave up last night and assaulted the rear fender wells on my car. I'm now on my second set of tires that rub the inside of them and I need it to stop. I have a decent Makita hand grinder and several grinding wheels I got for free from work. After grinding for a couple minutes - safety glasses, long-sleeved shirt and leather gloves in place - I stopped to look at my progress and basically there wasn't much. That was when I took a hard look at my grinding wheel. Holy carrot sticks Batman! The wheel was a masonry wheel with a max rpm of 8,750 rpm and I was using it on metal with a 10,000 rpm grinder! Fortunately nothing detonated before I wised up. Quick run to the local True Value hardware yielded a 4" diameter, 15,000 rpm rated metal cutting wheel, and I was in business.

Almost cut enough away but not quite. Need to trim a little more tonight and I should be OK - It only took about 1/8" of material to cure the problem but I just didn't remove it far enough around the fender well.
