I chose to go down a slightly different design path on my project. I hearken to the fine furniture builders of the past and eschew the use of mechanical fasteners in favor of tight fitting joints and glue. I was told once that fine furniture does not have nails or screws in it. Where I need to make a more mechanical connection I will use wooden pins.
Of course it must go without saying that power tools with sharp cutting edges will be used and all appropriate safety measures must be in place.
Bill of materials: 1 pine board, 46"X16" X 3/4"
dowels, 1@ 3/4" X 4"
2@ 3/8" X 2"
1 @ 1/8" X 2"
That's about it.
As with many new things I try I tend to make a prototype from cheaper soft woods to get the feel of how it will work, this is no different. If all works out to my satisfaction I will move on to a wood like maple or oak. Also, I'll fore go the staining and varnishing steps in this Instructable since it is only a prototype.
Thank you for looking and if you have any questions or need more clarification just leave a comment.
