Three sets completed. Two coats of oil/urethane, two coats of wax. Now on etsy, pentomino wooden puzzle.
Nine boards: three coats shellac, two coats wax.
About six sets of pentominoes, drying on pinboards made from cardboard and staples. These pieces were cut some time ago. I milled the edges with a 45 degree router bit, a new one with a 3/16″ diameter ball bearing, which reached much further in than the 3/8″ bearing I’ve used in the past. New blades for a utility cutter still did not do a great job notching out the remaining corners (a masons miter). I set up a grinder with a felt wheel and charged it with rouge, and polished the edge of the blade. The sharpened blade made a big difference, and I sharpened the blade four times for 300 notches in 90 pieces. Liquid hide glue cut 6:1 with water is the glue size. The water raises the grain, the glue hardens the nibs, and the sandpaper slices them off.
To sand. It’s a few minutes a piece. This is the critical sanding.
