Hello,
I am building a king sized bed, with the headboard mostly being a single 1/2″ walnut veneer plywood panel. The plywood is veneered on both sides. The upper and lower cross pieces surrounding the panel are 2″ x 2″ square solid walnut. The will be M&T jointed into the 2 3/4″ square leg posts. I was going to cut a 1/2″ deep slot into the frame to hold the plywood. Am I safe gluing the plywood into the slot all the way around? Or should I let it float free? I am assuming that gluing the panel in would make it stronger, but could cause problems as the wood shifts with the seasons. I understand that plywood is very stable.

Any advice would be appreciated.

Thanks,

John
