Last few construction photos

One afternoon I received this very excited email from Kirk Sand: "I just strung it up, and it sounds great! Right away! I can't wait to get the electronics in it!"


Here are a few more photos he sent that day. First, installing the Prismatone pickup . . .


A perfect fit! Kirk fashioned the bridge to receive the Prismatone without the need for intonation adjustment screws.


Now, stringing it up . . .


Beautiful! Kirk used D'Addario ProArte Extra Hard strings, with a Savarez Alliance 3rd string.


Here's a closeup of the bridge/pickup area.


And a view through the access panel.


Looking good!


Now, deciding on the input jack location. Endpin or side?

Next time- installing the preamp and wiring!

Gluing the bridge

I told Kirk Sand about 12-year old me gluing the bridge down on my old Harmony archtop guitar with some glue I found in my Dad's workshop, because it kept sliding around. (The bridge, not the workshop.) Don't worry, I marked the spot before I glued- by cutting a notch in the top of the guitar on each side of the bridge feet with a knife I found in my Dad's workshop . . .

Later, I received these photos, with the caption: "Gluing on your bridge with some glue I found in my Dad's workshop."

First, measuring for the right spot.


A trial run. The ebony block simulates the pickup, for precise placement.


Looking good. Hopefully, Kirk won't mark the spot with a knife he found in his Dad's workshop . . .


Kirk explains: "First we have to chisel away the lacquer where the bridge goes. Better measure twice, chisel once!" If you look closely, you can see the faint lines where he scored the bridge outline before chiseling.


Positioning and taping the bridge into place.


Drilling for dowels and the pickup wire.



Ready to glue.


Next time- the last few construction photos!

Making the bridge

While the first coat of lacquer is drying, Kirk turns his attention to the bridge . . .

"Any ideas on the shape?" he asked me. My ideas were something along the lines of John Knowles' bridge, but with swept wings to echo the angled fingerboard and heel, and the Brazilian rosewood wedge on the back. "I'll think on it," said Kirk. "The ends of the wings can be traditional square flat on the ends. I curved John's in a little. I'll play with curving the ends the opposite way."

Here's John's bridge:


And here's the rough drawing I sent to Kirk:


A couple of days later, I heard from Kirk. "It came to me in one second today. What do you think?"


"It is similar to John's, but not the same. It has the straight ends like your drawing. It mimics the other lines on the guitar too!" (That's the Prismatone pickup next to the Brazilian rosewood bridge blank.)


I gave Kirk the go ahead, and he went to work. First, he created an inlay for the tie block, using the same scheme as the soundhole ring and binding.


The finished inlay, ready to install . . .


. . . and a closer view.


Done! The tray will receive the Prismatone pickup.


Now, Kirk lacquers the bridge . . .



. . . and sets it aside to dry.


Next time- buffing and sanding the finish!
