Tool time Tuesday and it’s a tasty one today. Ever heard of a biscuit joiner? For some, a biscuit is joined by grape jelly or gravy and eaten. This biscuit joiner is a tool used to join two pieces of wood. The basic biscuit joining system was invented in Switzerland in 1956 by Hermann Steiner. Developments such as the circular saw and the first stationary biscuit joining machine in 1956 lead to first portable biscuit joiner in 1968. The tool cuts a oval shaped groove in each piece of wood to be joined. Glue is applied to a compressed, highly dried biscuit and the slots. The biscuit is placed in the slot and the two pieces are clamped together. The wet glue expands the biscuit which, along with the glue, improves bonding. I have one of these tools, but I haven’t seen it in a while. I may have loaned it out. Hey, if I loaned you my biscuit joiner, give me a call.
