What’s On The Bench – October 28th, 2018

Laying out a dulcimer peghead support block.

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.

Dulcimer peghead in progress.

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.

A glue up that is far less precarious than it looks!

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.

    Very nice Doug, Sorry I didn’t make it over this summer, will shoot for next summer. I am just starting a Ukulele using cross laminated maple for the sides and purple heart for the neck and back. Stay safe and take it easy on your back.
