I assume these are those kinda crescent shaped ones. I've used them for holding metal in position when welding. Did kill one of them by heating it. Forgot it was on the backside.
I have had some luck using non-ferrous metal wire brushes. I use brass, but I assume SS might work, or even ferrous brushes, but I think they might present problems when they get magnetized. I'm able to get 99% of the swarf, but there's always a little patch of "finer than sand" particles that I just push to the side I'm not sticking to the metal. Raymond Julian Kettle River, MN The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest are the traits of success. And while men admire the quality of the first they love the produce of the second. -John Steinbeck, novelist, Nobel laureate (1902-1968) On 11/12/2014 09:41 AM, Gene Heskett wrote: > Greetings; > > I was given 4 of the rare earth magnets used in hard drives yesterday, and > have visions of using them in lieu of holddown clamps for flat, non- > magnetic material clamps on my toy mill. > > These will exert 150+ lbs of pull when placed over a 1/8 masonite > sacrificial, with say a .090" lexan sheet laid on the masonite. > Restricting them to non-ferrous material hold downs should keep them > fairly clean.
