Jim had one stuck to the light gauge steel of a filing cabinet, and it took both hands & a brace his knee against the cabinet to slide it sideways off the edge of the cabinet. A straight pull? No way `Jose. Stuck to the top, it could have easily picked up the cabinet without unloading the several hundred pounds of its contents. > On 11/12/2014 10:41 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.
