Re: Using a dermal to cut your coals
I can't attest to using a Dremel on coals, but when polishing metals with a rotary polisher and rouge, it gets everywhere. Your snot, spit, ears, hair, face, and clothing will turn blood red. Hence: WEAR SAFETY GEAR. Goggles and a facemask at least. Doesn't really help with the ears, hair, or clothes though. Bandanas help.. Covering your hair and ears.
This is what happens when you don't wear saftey gear, kids:
(Btw, no my hair is not actually red in front. I was digging this stuff out of my ears for three days. And this is why you should not wait to polish all your metalwork pieces the night before they're due. I spent eight hours in front of this thing... You can see where teh saftey glasses were.)
