Working on a loft bed for my daughter, basically a bunk bed without the bottom bunk so we can use the space under it for a dresser/desk. The posts will have a bun foot at the bottom, then the rest of the post will be about 80" tall turned in two sections. My question is about the joint between the two sections. I could turn a tenon on one end of the bottom piece and then drill a mortise on the top piece, or drill a mortise in each piece and use a floating tenon/section of oak dowel in between. I'll be starting with 4x4" posts. The joint will be at a ring in the middle of the post.
Any thoughts on the ratio of the tenon to the overall width of the piece?
I attached a schematic of what I'm thinking. There will be a bottom stretcher it's just not in the model.
