I am an adult Scout Leader and need to make a "comb" for a beading loom for a Scout project. I'm trying to duplicate an existing comb that we cannot source anymore. It is made of thin solid wood (1/8 to 3/16"), and has vector cuts in it about .10" apart with a vector cut hole in the center of each tooth so thread can be inserted in the holes and slots. The cuts are approximately 4' long and the overall piece is approx 6 inches tall with reinforced edges to add strength. The attached photo I hope will make this description more clear. I am afraid plywood would warp and or leave rough edges inside the cuts from the laminations. Any suggestions for a type of wood or other material to use.
