« Part 3: More neck and pegbox Part 4 of Building something like a bass viol series Part 5: Peg Prototype »

What got my customer excited was a look at the box cello I made for my wife. I convinced him to let me try something creative to add some curves to this instrument. I’m making the body like I mede the sound box for my wife’s second mountain dulcilmer.

Fist thing was to cut the wood to a generous length and resaw it partially. Then I finished the resawing with a hand saw.

Then I brought them down to about 1/8 thick using my thickness planer.

I made a pair of endbocks from mahogany to match the ribs and slotted them to accept the sides. One block got slots at 15 degrees and the other (the bottom) got angle slots at 20 degrees. I did this to hopefully make the bottom of the instrument look a bit fuller than the top.

Put it all together with a spreader brace and the ribs are done. I’ve wetted the ribs several times hoping it will help them relax before I put the back and face on.

Please clarify: you wet the ribs?, or the sides?
Wait, I think your referring to what I would call sides as the ribs. Dang, I’m catching on to this.

Yes the sides of a string instrument are called the ribs. I could confuse you more and say that the whole assembly shown is sometimes* called the ‘garland’.

  • Some folks don’t call it that.

Interesting box, Dave. Good to see more pieces becoming a recognizable instrument.

When you say garland I want to put it on my head and go dance in a meadow. ;-)
