I see what BJ meant about voids. The are clearly visible in the seams, but notas frequent or large as some other types of plywood. Oh well, it's done now.

Anyone know how to mount thread inserts?

just a drill and some wood glue right?

If you are talking about the threaded inserts I think you are, just drill a whole and screw them in. Make sure you use the recommended pilot hole size.
