🪵 Hygroscopic Wood Joint: Shrinkage, Swelling and Friction Grip (2D)

End-on view of a pegless mortise-and-tenon joint in which the tenon and the piece with the mortise take up or lose moisture at different speeds. Set the size of the tenon, the moisture of each piece when assembled, the humidity of the house, the clearance cut in the mortise and whether the grain of the mortise is turned, and watch the fit tighten or loosen over four months, with the contact pressure and the pull-out grip. The sorption curve, the diffusion through the board, the scatter of fits and the conservation of moisture are checked numerically, with four in-page numerical checks.
