I made an interesting discovery today. I have had the CBN wheels for years. I took a Moffat (brand name) lamp down off a shelf that was about 30 inches above my grinder. It was still in the box, one of the kind with the 1/4 round dog ears on the lid that tuck into the side of the box to close it, but not taped. I opened up the box to check on the lamp and found a ring of fine metal dust on the smaller box that had the magnetic base in it. I had always thought that the metal particles were too coarse and too heavy to float around like that. Ralph Lindburg, a turner from up in Washington said that when he was in the Navy, full respiratory protection was required for any metal grinding or chipping.
