Looking good, Splinter. I'm anxious to see all those pieces come together.
Like George, I'm liking the looks of that plunge base for the Colt. My Colt is years old and still working, but the shaft lock button no longer springs back once released. I have to lever it back out after a bit change. And the threaded shaft to raise/lower the motor was always a bit clunky. I'd definitely look at other options if the Colt expired, but that plunge base could be enough to pull me back.
