Here is a picture of the micro drill kit. I used Texas Chert for the drill tip, and bamboo for the shaft. I tried on a piece of clam shell I collected in Ocean City.
At first, the drill slipped off the shell because there wasnt anything for it to grip into to stay in place. So I used the handdrill technique to get it started, then switched to bow drill.
I'd agree with Morse's findings that it took 10 minutes to drill with bow drill. It seemed to take about that long, though I didnt time it.
Right after drilling through. I continued drilling to widen it slightly.
And here is the bead being roughed out. I dont have a picture yet of the finish product, but I will later.
