I'm building a king-sized bunk bed using a loft/joist design. Basically, I've got (see below):
- slats nailed into joists
- joists joined to headers with blind tenons
- headers joined to posts with blind tenons
My current goal is to build it without glue, so I need some way to keep the frame in tension. I was originally thinking dovetail joints or tusk tenons, but I just had the idea of using turnbuckles, instead.*
I'd run cables between turnbuckles and eyehooks, one head to foot and the other side to side. The head-to-foot cable would thread through 1/2" holes drilled into the centers of each joist. So:
- Is this done, or am I making up something problematic?
- Will the eyehooks pull out of the joists?
- Will the holes in the joists weaken them substantially?
- Am I overly concerned about my ability to make long-lasting dovetails or the difficulty of making tusk tenons? Those are aesthetically more pleasing anyway, so should I just bite the bullet and use one of them?
* I really the idea of a dovetail, but I'm concerned that between my novice craftsmanship and the wood shrinking, they'll eventually pull out. I was thinking of using a tusk tenon when I realized that that joist would only really be good for tension, and if tension is the goal... cables can do tension...
