Zampogna and harp duo
I don’t have a standard pattern for dulcimer back braces. I don’t have a standard pattern for bracing dulcimer soundboards either. The bracing pattern, number of braces, and size of the braces depends on the sound I am after and the wood involved. It would be easier and faster to standardize things but that wouldn’t be any fun at all. I also find the results I get from taking the long route make a big difference in the sound of the dulcimer.
In the photograph above you can see the four planes I use to dimension the back braces. The braces are brought to approximate size and then shaped after being glued to the back. This dulcimer back has three spruce cross braces and a Spanish Cedar reinforcement over the center joint.
After getting the braces roughly to shape I do most of the final shaping with a paring chisel. In the photograph below you can see the paring chisel and the cute little shaving it makes. You can also see what a neat and highly organized workbench looks like.
After using the paring chisel the shaping of the braces is complete, though sometimes I will sand the braces as in the completed back shown below; it just depends on what I feel like doing. Sometimes I prefer the crisp, clean lines left by edge tools, other times I go for the smooth and rounded look left by sanding.
Next comes fitting the braces into the side linings and gluing the back to the sides.
