Putting binding around the edges of the soundboard, especially a soundboard made of a soft wood, helps prevent dings and chips along the edges. To my design aesthetic binding the soundboard is also like putting a frame on a picture.
I usually do not put binding on the backs of my dulcimers unless someone really wants it. I don’t think it is necessary to bind the back since it is usually made of hardwood. Also, should the dulcimer ever need major repairs an unbound back simplifies removing the back of the dulcimer to gain access to its innards.
In the photograph above are the hand tools I use when preparing the dulcimer for binding.
In the upper left is a shop-made binding scribe. It consists of a scalpel blade glued and taped to a piece of wood the thickness of the binding that is again glued to a piece of wood that serves as a handle. I use this tool to gently score the binding channel on the soundboard. After the channel is scored I deepen the scored cuts with the scalpel and knife.
I use a simple router jig to remove some of the bulk and then finish up the binding rebate with the small chisel and file. I also use the chisel as a scraper, using my fingers as a depth stop to guide the cut.
After taking the photograph for this post I noticed the fingerboard did not look quite right. I realized I had left out one of the fret slots! It has since been cut and all is right with the world.
Forgetting to cut a fret slot is not a big deal as it is easy to add at anytime. What is a big deal is cutting a fret slot where one is not supposed to be.
Guess how I learned that lesson?
I have basic patterns for my dulcimers but the the exact shape and size of each dulcimer varies slightly from one dulcimer to the next. I have embraced a fairly free-form style of building and use very few jigs, forms, and fixtures.
By building free-form I feel like I am sculpting a dulcimer rather than making a bunch of parts and assembling them. The frame of the dulcimer (sides and end blocks) and the fretboard become the reference points for laying out the rest of instrument. I can make small changes to the shape and size of the dulcimer by feel and eye and work with it until everything seems right to me.
The thickness of the top and back and the bracing pattern are determined in a similar manner.
Free-form building is not the most efficient way to make dulcimers in a timely manner. If I made all the parts to a set pattern and assembled them in fixtures I would make more dulcimers in less time but I wouldn’t enjoy the process very much.
These photographs are of a baritone dulcimer in progress. The final shape of the dulcimer is traced on the soundboard and the soundholes are laid out using a template. I have also laid out the placement of the position markers on the fingerboard. A scraper serves as a short straight edge for drawing the layout lines.
