i choose no fiddles because i like to sit at the table with my forearms resting on the edge of the table ( mother always said don't put your arms on the table) and fiddles make it uncomfortable doing that ....so for things slipping of in rough water i will use some kind of matte that is rubber based to slow that down some.....Yeah, I wouldn't use epoxy for an interior lamination like that, either. For properly smooth, tight joints, clamped well so that the glue doesn't foam up, Gorilla Glue is a fine choice for this application, and even Titebond 2 or 3 would be good also.
That is a great looking table! Do you feel the need for fiddles on the sides to keep stuff from slipping off? Or are you only using the table in a protected area with limited wave action? Do other boat wakes disturb a table enough to require fiddles? These are questions I've been wondering if I build a table myself…
