holy c***. free-hand grinds about a #68? .79mm?! of particular note- he perfectly grinds the tapered section straight keeping runout to an acceptable minimum on a shaft that tiny??? as i said- holy c***.

I wished my hands were that steady, good job

The calluses on his hands must be tougher than the burs.

That gives me an idea for making undercutting tools. Sam. you've got a genius of a mind and steady hands. Like Don Gay once said there is no substitute for youth.

i have quite a few re-manufactured bur tools. my best to date was a flat .2mm wide graver. that was a bugger to do, and get it right. i made this for doing hobos. this "bur to drill thing" would be enough to send me over the edge. hats off to those with such a touch to pull this off & make it work.

Sam one question, are you using the blue medium wheel to preshape the burr or the grey coarse one?

Impressive. Most impressive. Jura does beautiful work and occasionally pops onto the forum.
