This week began a Weissenborn project. Based loosely on a style 3, this page I will highlight photographs of its construction. I will update it as I move along its completion. This is a special build with a delivery date of Mid April.
About the woods: This was constructed with Koa back and sides and an Alaskan sitka soundboard. The fingerboard is Macassar Ebony and came from LMI. The headstock is Mahogany which came from a 3×3 billet from Hibdon Hardwoods. The bridge of Honduran rosewood was also from Hibdon. The binding is a traditional Rope design made from scraps of maple and mahogany. The head plate is Koa. The pearl rosette was from the Duke Of Pearl. Ebony bridge pins with Abalone inlays were used and the position markers are Abalone too.
The Koa back and sides came from Notable Woods in Lopez, Washington. These are age dried pieces of Koa with a nice tone and appear to be very stable. The Sitka soundboard is of salvaged wood from Alaska Specialty Woods, Craig Alaska. The story behind the soundboard is that it came from a bridge stringer that once spanned over Back Bear Creek. It was a 63″ diameter log that was aquired by the mill in 1998, about 2 years after the bridge was pulled to be replaced replaced with steel bridge. The wooden car bridge was installed when the road there was used for logging in 1984-85. Now that road is used for recreation and to get to a hydro electric generator were water falling off the mountain from black bear lake is run through a turbine. The build is based on a template from Waldon Instruments. I have modified my braces to suit my building style.
The headlock, which is actually the neck block too was fabricated from a solid piece of mahogany
When I removed this guitar from the form I noticed something unique to the instrument. When I tapped on the center of the soundboard, sort of a thump with my thumb, I was able to hear the sound that produced come out not only from the sound hole but I also heard it way up in the headstock. The vibrations traveled straight up through the hollow neck and emitted at the top of the guitar.
I have a little music box mechanism that plays a simple tune very quietly when you crank the handle. Barely audible without something to amplify its sound, like a wooden music box. I place it where at the bridge position to test the guitars responsiveness to a very quiet sound, essentially making the guitar the music box. (try it one day) The sound is greatly amplified and comes through the sound hole. When I put the mechanism at the top of the neck the sound transversely traveled down and out the sound hole almost as loud as from the bridge position. I am certain that the energy from the nut will also travel through the guitar and add to the sound of this instrument. Perhaps thats is little secret behind the Weissenborn’s unique sound.
The initial stringing sounds awesome. I used John Pearse Weissenborn strings, 80/20 bronze, 15 to 60. A final adjustments for string height and level across the tops will be performed, but as it is this Weissenborn has a rich tone, a beautiful natural reverb, good presence and response, and a lovely character.
Thanks for looking. I hope you have enjoyed reading this as much as I have enjoyed building it!
