In the home stretch..kind of. Shaping is nearly complete. I’m still working on the bottom and I need to do more work on the two holes and a few areas on the sides. But then comes the painstaking work of sanding and polishing..

Damn! Lookin good!
I'm curious about how you do the internal corners. Pics when you get to that?
Like in the holes? And the top and bottom? You can get pretty close with rotary tools, but after that I’ll use diamond files
Yeah, the middle part that you're working on, since there's no elbow room in there. I'm imagining like a dremmel tool or something. Also thinking about the internal corners in some ancient structures, which seem impossible, but idk.
Ya basically I have an electric die grinder with diamond bits. It’s long enough to reach in there and I just have to go slow and steady taking stone away till I get that corner. Then follow it up with a flat diamond file
