I recently had the need to secure a top to an irregular box using glue and biscuits and was successful using careful measuring BUT the following idea came to me. Why doesn’t someone make a biscuit positioner similar to that used to position the mating dowel holes. For doweling it is a simple metal dowel that has a ridge and a centering pin. For a biscuit it would be about 60 percent of the curved part and three pins that would show where the mating biscuit cutout should be. I passed this idea on to Rockler product development this last week so we may see this become available.
