Came across this. I know it came from one of the BB's some time ago. May be of interest to some.

I've drilled a lot of small holes, manual and cnc, but I have never done it that way. Pretty cool the way he put the center spot in the part

His little drill press he made is really sweet.

The r p m he is using is much too slow for a drill that size. Assuming the drill is around .020 the speed for brass should be cs x 4 divided by .020 = 200x4/.020 = 40,000 rpm. I mount a dremel flex end in my qc toolholder and drill carb jets by rotating work at 2000 and the dremel at 30.000 and peck drill with the carrage. Made lots of jets this way. Peter

Talant, art and a practical tool all in one. Thanks for showing it.
