Topic tags/keywords: oak plywood core

I’m about to start work on a dining room table and the plans call for laminating (3) 3/4” boards together to make a core for the legs, which are then faced with good quality stock. I don’t have a lot of scrap oak lying around in the dimensions needed to make the cores, but I do have a ton of scrap birch ply. So, my question is: is there any reason I can’t (or shouldn’t) use the plywood to make the cores?

Go for it. The plywood will probably be more stable than will solid wood. Probably a bit lighter weight than would an oak core.

I agree plywood would be very stable, but could there be an issue given the plywood expansion and shrinkage (generally low) would be different from the material for the facing?

I don’t know that it would be, I just wonder if it could be.

Thanks. I didn’t thiink it would be a big problem, but I thought I should double check, just to be sure.

Also, the plywood might not be exactly 3/4” thick so you’ll maybe need to glue an extra layer of ply, and once the glue-up is done, rip down the thickness.
