120 chips MUCH SHARPER than 90s

I read on the Cafe some time ago to rub aross the surface with an old(copper) penny and it will take up burs without damaging the surface. I do it and it works. I now collect all the old pennies I find but I am still using the same one i started using 2 years ago. Does anyone need a penny?

By the way, Harbor Freight has a cheap card of "dental" tools for about $6.00 which includes a fine point set of tweezers that work pretty well for removing the metal chips that Mitch was referring to. I have used them many times myself for the same reason that Mitch mentioned.

I should mention that highly polished gravers produce even nastier micro chips)))
