Me too. I used to have an article on how to sharpen hand plane blades to cut atoms. Basically a similar thing - multi sandpaper grits (stopped at 1200) on three angles (like a good valve job) done on a piece of tempered glass. I could cut the end-grain on boards and it looked like glass.I'm liking this thread.
I used to paint cars and would change the angle (?) I was sanding when changing grits. It makes it really easy to see when you sanded out all of the courser scratches out.
That may be too much trouble on something that small though.
My wife used to like how smooth my fingers were from all of the sanding.
When do you want to do one of my glock barrels?![]()
