Well there's one I haven't seen before. :-)

Sounds like it works great, but since those are metal casters on what
is now effectively a cast iron "runway", I'd check every now and then
to make certain they aren't peening the corners of the miter slots out
of shape. I think it might deform the corner slightly, which would
create a slight bump at the top of the table and inside the slot.

I don't know if this would be a problem or not. The more weight on the
casters, and the more use, the more it would be a factor. Since you're
pioneering you might want to keep an eye on it.
