Yeah, recessing was the plan for the T-nuts, but they'll actually end up on the under-side of the table (top side of the seat). I was looking for ways to keep the top surface of the table (opposite to the seat) as 1 smooth surface.
But this reminds me of another question... should I do anything else to in terms of waterproofing around the T-nuts? Since they will face up during the on-river time, they may collect water. Will the gorilla glue provide enough water-proofing here... or maybe a thin coat of epoxy or varnish before gluing in the T-nuts?
