Cello bridge fitting jig

I made this oddball little helper as part of my journey in lutherie. I need to fit a new bridge to the 3/4 cello that I recently repaired. Part of the process is to make the ‘feet’ of the new bridge conform to the curved surface of the instrument in the location that it will be put. While experts may be able to do this by hand and eye, it can be more efficient to use a jig.

Manufacturers will let you buy something like this (6th picture) for tens of dollars, but I decided to make one out of some scrap mahogany. I did buy the brass hardware and the little wooden wheel. Well, I had the wheel and several of its brothers for a project I never got to.

I haven’t used this yet, but I can’t see why it wouldn’t do what it was made for. Anyone want to see how a bridge is fitted?

The finish on this is Danish oil.

In theory, I’ll be fitting the bridge this weekend. I’ll document it and post it. This will actually help me learn. I owe someone a bow rehair post as well.

Dave, I don’t know the first thing about lutherie; however, this sure is a beautiful tool. I suppose that you have all sorts of tools, gadgets, and fixtures for this sort of work. Congratulations on the making of this beautiful tool.

You’ve made me feel a lot better about posting a jig as a project. There are a lot of odd tools associated with this craft. A lot of them are clamps, but most of them are metal. I might put them on my blog, especially after they’ve been used.

There is a less exciting companion to this jig which lifts the strings off the bridge. It’s now in progress.
