I made this mold set for a friend of mine who is into making pottery and also into cacti and succulents. With this mold set one can take a 1/4” thick sheet of clay and lay it into the slump mold, the hollow piece, and press it with the hump mold, which is the solid piece. Trim it and remove the hump mold and let the clay harden to a leather stage then unmold it and it can be glazed and fired. The result will be a tray that can be a succulent planter or just a tray for other stuff. The sides are tilted at 30 degrees from vertical and I used Matthias Wandel’s splayed miter joint calculator to get the bevel and miter angles of 26.57 degrees for the miter and 37.76 degrees for the bevel setting. Those double beveled angles can be cut on a tablesaw with the blade tilt and miter gauge or on a compound miter saw. I doweled the miters together to strengthen them and finished with water based polyurethane. The inner piece is sized so that when there is a 1/4” gap between them at the bottom there is also a 1/4” gap all the way around on the walls.
