Mini slabbing boulder opal with a flex shaft- can we take a slice off this boulder opal?

We try to slab a nice chunk of boulder matrix opal. Started out planning two cuts but we got off the rails a bit- some good and some bad. But in the end, we still ended up with three stones and I'm quite pleased with the results! Thanks to Patrick Patrikios    / @patrick-patrikios   for the music!
