Long story short, but on a drafting table I'm building, I have an area inside that will still be visible with some pocket hole joinery and a few screw heads that just don't look good visible.
It seems my best solution would be to cover over the pieces of wood with another piece of the same sapele. I would think that wood movement wouldn't be an issue that way either.
The problem - the top and sides of the pieces of wood that will be covered already has several coats of Waterlox varnish on them.
Do I have to sand the pieces down to wood before gluing with Tightbond, or can I just use epoxy to glue the varnish finished wood piece to an unfinished piece of sapele?
