A Custom 5-String Fiddle Progress Report

My Neck and Scroll process

When I first began making instruments, I laid out the scroll with a pencil and simply started carving. That was extremely labor intensive and not very accurate, either. It was very easy for me to lose track of where I was going, and ruin a scroll by carving away wood I really needed. (That is a “bitter pill to swallow,” having to scrap a scroll and start over.)

Learning from a Better Maker

So, what has changed? I observed how a viola maker in Brazil (Luis Manfio, of Sao Paulo) carves his scrolls, on a photo-essay he once posted. He used a fine saw to cut “tangents” to the scroll pattern, and then used the same saw to follow the side surfaces of the scroll and remove the scrap wood. It was a much better way than I had been attempting, so, ever since then, I have followed that path.

Here is what it looks like, using the current commissioned instrument as an example:

The resulting scroll blank still needs more tangents cut.

This is how the final tangents look. (Notice, too, an “error” pilot hole. It will be plugged befor the real peg holes are drilled.)

Then I carefully cut away the waste wood from the center area of the scroll, using small gouges.

Installing the Fingerboard

Once the scroll is close enough to correct that it will not be changing much, I trim off the excess wood from the sides of the “handle-portion” of the neck, and temporarily install the fingerboard.

The next step is to install the neck into the neck-block on the instrument.

We will talk about that later.

 

Thanks for looking.
