A venture into the "dark side" in time for Christmas. I'm making an electric upright bass for my eldest daughter Becky. It will have a variable scale length of 950-1000mm depending on where the bridge is placed. The body and neck will be made from Port Orford Cedar from a tree that grew in the front garden. The body will be covered in Sapele veneer front and back and the fingerboard is East Indian Rosewood. The tuners a Hipshots and it will have a K&K bass pickup. This is very much going to be a "make it up as I go along project" in other words fun Here are most of the parts: The beginning of the plans: The East Indian Rosewood fretboard is glued to a piece of Port Orford Cedar to make a composite fingerboard thick enough for a radius to allow bowing as well as plucking but also light in weight: Fish glue is used and other fingerboard blanks are used together with clamping cauls to keep the composite fretboard straight as the glue dries:

I was wondering if you'd put a build thread on here, Dave I'm also keen to hear how this turns out... In time for Christmas, eh? You must be one of them types that enjoys the pressure of a deadline

A bit more progress. The fingerboard taper is cut and the initial radius put on the fingerboard. The final radius will be done with the strings on: The fingerboard has the East Indian Rosewood bindings glued on the side and end using fish glue: The scarfe joint is cut in the Port Orford Cedar neck blank and the two pieces glued together using hot hide glue in this jig: Here’s the neck blank after tidying up the joint:

What's the final radius to be, Dave ? Looking good.

What's the final radius to be, Dave ? Looking good. Colan, Not sure - whatever works for bowing. It will eventually be a compound radius with about 50mm radius at the nut end and 75mm radius at the bridge end . . . or thereabouts The cross section will also probably be more parabolic than circular I suspect.

Looking great Dave.
Are you going to some kind of support of a CF/truss rod for the neck?

Looking great Dave. Are you going to some kind of support of a CF/truss rod for the neck? Shubbs, Funny you should ask Last jobs for today done: The volute on the back of the headstock is shaped in the thickness sander: Slots are routed in the neck for two 8mm carbon fibre rods: The carbon fibre rods are fitted and a Port Orford Cedar cap glued on top – here’s the first cap glued in: With the second cap on the neck is clamped until the glue dries:
