Hi,
I'm building a bookcase for my son in law. The plans show the front and side rails of the base are joined to the legs with a mortise open at the top and a 1/4 " tenon with no shoulder. Can these rails be made from 3/4" plywood or would a tenon cut into plywood be to weak to support a bookcase? Or could this joint be made with biscuits using plywood for the rails or should I jut use standard dimensional lumber.
TIA
George
