I know how to attach a table top and allow for wood movement. I know raised panel doors allow for it also. . . . . . a little knowledge, etc. . . . .
What about serving trays?
I'm making a serving tray with a 5/16" thick bottom. The tray will be about
20" x 12". Just a simple frame with a rabbet on the bottom to accept the base. If I never knew about wood moving, I'd just glue it in place, maybe a few brads. I'll allow some clearance, of course, but if it is glued, will the movement be a problem? I have a vision of the bottom popping out or on a humid day looking like a peaked roof.In case you are wondering how I arrived at the 5/16" bottom, it was not very scientific. I resawed some 6" wide maple. I planed it to get it fairly smooth to glue up. On the last pass, the blades wanted to tell me it was time to replace them. After gluing it up, I just ran it through with the new blades until the divots went away and that became the final thickness.
Since it will hold beverages, maybe with alcohol, the finish will be poly.
