Hi, I'm new to this forum and have a question perhaps someone can help with. I am working on a few projects, one is a wood tray I rabbeted the hardwood sides to hold the 1/4" plywood bottom. I made a few and glued the plywood into the rabbet. I like the added rigidity but wonder if this could be a future expansion / contraction issue.
Second project involves gluing oak flooring to a 3/4 birch ply base, cutting into a shape and edge banding it, with the same expansion / contraction concern.
The glue is titebond ultimate, the slower setting one.
Thanks

Pics would help, but as a general rule, gluing plywood into a wood frame is fine. The plywood does not expand/contract like a solid wood panel would, and the frame parts are usually small enough in width (less than 4" or so) that everything is stable enough.

Oak flooring on plywood could be a different issue. It will depend a lot on the dimensions of the piece. If large enough and unsupported (as opposed to actual flooring where the plywood subfloor is fully supported by the framing structure underneath) the piece could warp due to the different expansion rates of the oak vs. plywood.

For a small piece, you could probably get away with it. You might, though, end up with some gaps at the joints between flooring boards.
