So in the stick chair book, the first chair calls for a 16x20 seat, 2" thick. It goes through the process of joining two boards together with floating tenon's and pegs, or says you can use a wide board.
I have called several wood dealers in my area, and finding a 16 wide plank two inches thick isn't a small task.
At the local yard waste center, people frequently drop off logs from yard cleanup, tree trimming, etc. Sometimes good straight chunks of logs can be found.
I don't want to mess with cutting floating tenon's, with or without a Domino. I am thinking of cutting a section of log and splitting out a thick chunk to use as a seat.
My worry here is warping, cupping, etc. I know old chairs were made with green wood, but I don't know if that was old growth timber which would be more stable.
I know I would need to avoid a piece with pith in it. Logs two feet in diameter are not uncommon there, so I was thinking I could split a piece between the sapwood and pith.
Has anyone tried this? Once the piece is split do you have to seal the ends and dry it like you would a piece of sawn timber? Or is it useable almost straight away?
