Finished at last! I built this ‘something like a Gamba’ on comission for a co-worker who admired the Box Cello [link] that I made for my wife. I had to create every part of the instrument except for the strings as no stock cello parts would fit.

The neck is made from a laminated sandwich of maple clad with white oak. The body is mohogany on the sides with a one-piece oak back and poplar front. The matching fingerboard and tailpiece are mohogany over white oak.

The tuning pegs are mohagany and the custom bridge is from oak. A little unconventional, but everything came together well.

I designed the instrument starting from basic dimensions from a 1/8 size double bass (body depth ) and adjusting them with those of a cello (waist size, neck length/fingerboard projection.) The crescent-face scroll is my own design as are the tuning peg knobs. I also had to figure out how to stretch the peg box to fit 7 tuning pegs without the strings interfering with each other. (Wishing I had used AutoCAD, but I did it with pencil and paper.)

I did find some dimensions online, but truly I say to you, free information about building these instruments is a rare thing on the internet.

I finished the body and neck with golden oak stain followed by several coats of sacreligious spray lacquer, but the fingerboard and tailpiece are treated with boiled linseed oil.

The customer assures me that we will see something played as soon as he gets used to the instrument.

Very nice, Dave! Great to see it together after watching the build blog, and the whole is certainly more than the parts.

Sometimes I feel like I’m flying by the seat of my pants, but I’m very happy with the result.

Excellent craftsmanship on this Dave, the attention to detail in the build, along with the knowledge of the requirements for creating this instrument, clearly show your dedication to this craft. Looking forward to hearing this being played.

To me this was essentially a mountain dulcimer with differences. The rest is just measurements. ;-)

Thank you! I’m going to say this was actually fun to figure out. The customer was patient and excited during the whole 6 months it took to make in my spare time at work.

That is pretty cool instrument. If it sounds half as nice as it looks, it will be a winner.

Four years ago I said the same thing. It’s definitely a learning process.
