I will give this a shot and see where it goes. The concept is to use a La Flor Dominicana cigar box, where the bottom neck will be a 3 string electric guitar. I'm leaning towards making one of those "blues chimer" I've been reading about. The upper neck will be a lap style dulcimer (also 3 strings). There the box is with a cut out for the fret board. I've already glued in the bracing for the necks with slots for the necks. The hole in the bracing allow for the wiring. The ends of the necks only go as far as the last bracing, which will allow for the electronic components in the last section.Here are the 2 necks that have scarf joints and holes have been drilled for the tuners. The jig below is what I use to cut the scarf joints. The jig is clamped onto my miter gauge on my little Skil band saw. I used a forstner bit to cut away approximately 1/8 inch on the tail pieces. Ode to have a real band saw to do some resawing. It's starting to come together. I'm waiting on the fret wire, wire bundle, and a piezo bridge.
1/19/11 Just a quick update: I cut out additional areas on the neck to accommodate the pickup and the extra bracing under the bridge. Strings will go through the body. Also, cut out the pickup opening in the top of the box and made a piece to cover the uneven edges. A possible issue is the current height of the pickup and there is not much more I can take off the neck. I'm debating if I need to raise the bridge by a 1/16 inch or so. Some more parts arrived in the mail today--piezo bridge and wire bundle. Now to deal with the fretboard.
Hope to install the fret wire today and apply another coat of poly to the necks.
Life and technical difficulties have made finishing this project rather difficult. Anyway, I have strung it up and here is what it looks like. I need to remove the top and look at my wiring, as the piezo bridge is only working when plugged into the amplifier.
