These guys (www.collinstool.com/collins_ply_prep.htm) sell a router
bit to put a concave edge on plywood in preparation for edging. They
claim that some of the inner plys swell when glued and cause a small
open seam between the edging and the face plys. Seems to make sense,
but what is the opinion of the group?

Thanks, all.

I've used solid edge banding on ply many times with the edge just as
it was cut by the table saw and had no problems. I sure wouldn't want
to take the time to run a router around every piece that was being
edgebanded for a problem I don't have.
