I would be interested in another test.
My surface of my router table is flat and all at the same height because I took a small cut on the table surface with it's own router.
Is the Vac-clamp parallel to the feet? What I mean is if you bolt the vac-clamp down to a flat level surface, and you clamp a board on top of it. Is the board parallel to the table surface? If not, how far out is it?
Thanks
