Now the gap between the center 2 boards
(previously about .040) was now double that! The Tru-Grip is not bowed
and I kept the point of contact between the router base and the
Tru-Grip at the same position for the entire cut. Also the gap can be
seen from top and bottom.

The first issue confused me . . . the 2nd is shaking my faith in
geometry.

Anyone have an idea why this is happening?

Thanks,

Even though the TG seems not to be bowed, is there any chance it is
giving in the middle under pressure to keep the router against it?
That's the only explanation I can think of.
