Tenons on an 8" wide board
I'm building a twin bed for my son and am currently working on the head and foot boards. The bed posts are 2 3/4" x 2 3/4" and I will be using a mortise and tenon joint to attach the rails between(these are the rails that go side to side between the posts, not the long bed rail that runs the length of the mattress). The rails are 1 1/2" x 8 1/8" wide, and I know I shouldn't use one huge tenon, but am unsure if I should split this up into 2 or 3 tenons.
I'm also curious since I will be using multiple tenons, whether all tenons should be glued, or if I would just glue 1 to allow for expansion and contraction. This makes sense to me in order to allow for seasonal movement, but it also seems like I would be giving up some strength by not gluing all the tenons too.
