Just an update.
So I received the grinder. I am in the middle of wiring the VFD and motor, but I have to say a few things.
He says he assembles and tests them before shipping... and I didn't expect assembled meant it was entirely built and shipped in a giant box. It was. And the fit and finish was very, very good. And the oddities are like a nice pouch with the drive wheel instead of a box or bag. In the box were bolts to screw to mount the base to a work surface (too short for me but nice; my worktop is 1.5 inches thick) and screws to mount the motor I didn't buy from him, and two little notebooks. That is not something I expected. Oh, and a cheap wrench set was included just in case I didn't have what was needed.
Oh, and switching from horizontal to vertical is absurdly easy and toolless.
One oddity was that it said it included: a Flat Platen attachment w 1.5" x 16.5" aluminum tooling bar, an adjustable Work Table attachment w 1.5" x 16.5" aluminum tooling bar, and an 8-inch contact wheel attachment. I didn't expect the contact wheel to come on ANOTHER tool arm. That isn't a big bonus, but it was a bonus that wasn't listed. Now I have some easy swaps and don't need to worry about moving things between arms. Oh, and the arms are solid aluminum.
It was the little areas that he spent time on that I had never seen on any industrial-type equipment. This felt more like buying a nice CKF knife or a nice 1911. The little extras wow you.
I was incredibly impressed.
Now I gotta get a lunch break to finish that wiring, bolt it down and get it running!
