The Harmony Concert Party
On the bench is a cherry dulcimer ready to receive its peghead. In the photograph above is the block that gets glued to the end of the dulcimer to support the peghead. Layout lines are in place to guide the process of shaping the block.
The block is shaped and the gluing surfaces are flat and true for a perfect butt joint. I said butt, huh, huh, huh… Also in the photograph is the blank that will become the peghead and a cardboard template with the basic shape I’ll be using.
I use hide glue for gluing this joint. I could get an excellent, strong joint without clamping just by using a rub joint but I’m using a jack plane as a weight while the glue dries overnight. It is not necessary but it couldn’t hurt. Rub joints are made by applying glue to two perfectly mated surfaces and gently rubbing the pieces together until the glue begins to stick. After the pieces no longer slide I hold them in place for a minute or two and the joint is complete. As hide glue dries it pulls the joint tightly together.
Here you can see the completed joint and a good view of the sound port; a soundhole in the side of the dulcimer. I use sound ports to change the frequency of the air space within the soundbox, get a larger soundhole without removing more material from the soundboard than I prefer, and so the dulcimer can be used as a birdhouse should the need arise.
