Hmm, that's interesting John. I always get to a point where I can't thin a preform anymore, and it's thicker than it should be. Maybe I need a smaller bopper? I need to order a new one anyway, I've about ruined the one I bought. Of course it's made a lot of the pile of rock on the shop floor too.
And I agree, it is a treat to watch Don work. He is VERY patient. No wasted swings, and looooong thinning flakes. His preforms almost look like slabs, they're so evenly thinned. What a master! Can't wait to sit and break some rock up with him again. I would like to sit and beat up some rock with you too, especially to see the ABO work.
