Re: [CAD_CAM_EDM_DRO] CNC drill sharpening

Yo Elliot;

For a setup that would work on either a mill, or a drill press, how about a
grinder bit in a Jacobs chuck, and on the table, a rotary table mounted on a
sine plate? On a drill press it would bw a little tricky without an xy table,
but should be do-able, by eye. Of course some of us would need a pair of those
frog-eyed magnification goggles, made by the Nippon Coke bottle bottom and
optical company.....:-)
