Roughing Out the Insides of Plates and Cutting f-holes

After the outsides of the plates have been carved and scraped to their finished shapes and the purfling has been installed, the next step is to trace the f-holes onto the top. The f-holes will be cut out after the inside of the plate has been roughed out and the plate is thinner, but this is the time when you establish their positions. Measure 19.3MM from the edge of the plate at the neck end to find the bridge position on the centerline, and locate your f-hole template by referencing off of the bridge position and the centerline of the top. You can play with how they are angled to suit your own tastes. Trace the f-holes onto the top, and check to make sure that they end up an equal distance from the edges by measuring with a divider.

The French always carve little hollows where the lower wings of the f-holes will go so that those areas will be recessed on the finished top. So after you have traced the f-holes, you gouge, plane, and scrape the wing areas out a little bit. In the process, you will cut away parts of your lines, so you will need to retrace them.

Nuts and Bolts for Bridge Gluing

Nuts and Bolts for Bridge Gluing

by Tim Olsen

Originally published in Guild of American Luthiers Data Sheet #126, 1979 and Lutherie Woods and Steel String Guitars, 1998

 

The holes of a pin-style bridge provide a golden opportunity to apply some very convincing clamping pressure. I use 3 10×32 1" round-head bolts with washers, wing nuts, and pieces of drilled shoe sole leather to temporarily bolt the bridge on while gluing.

This not only exerts a strong pressure to the back edge of the bridge, but the bolts ensure an accurate alignment of the bridge. All that remains is to set a deep-throated cam clamp on each end of the bridge. The leather washers will take up any slop that the bridge might have. This is a natural for repair work as well as construction. ◆

Grading on the Curves

Grading on the Curves: Fitting Bars and Bridges on Archtop Guitars

by Steve Andersen

from his 2006 GAL Convention workshop

Originally published in American Lutherie #91, 2007



The first thing I’ll show you today is how I fit tone bars to the top. Then I’ll talk about fitting the base of a bridge to a top, first with this router jig that indexes off the top and gets me really close to the final shape, then moving on to the final fitting. I brought some extra materials if anyone wants to try hand-fitting an ebony bridge or a tone bar.

I use the term tone bar, because I think of braces as being structural. If you built a flattop guitar without braces, it would just fold up. An archtop could be built without braces and it would hold up fine. The archtop’s bars are not so much for structure, so I call them tone bars.

One thing that helps me in the fitting process is that my arching is very consistent from guitar to guitar. The arching templates for my guitars started out based on a D’Angelico New Yorker, and have evolved over the years to what I’m using today. So while I have several body sizes, they have similarities based on what I’ve found works well for my sound.

Thoughts on Violin Setup

Thoughts on Violin Setup

from his 2001 GAL Convention workshop

Originally published on American Lutherie #71, 2002 and Big Red Book of American Lutherie Volume Six, 2013



In a very real way, speaking here today is the realization of a dream. I came to Tim Olsen’s shop on Park Avenue years ago when he was still making guitars. One of my uncles, who lived in the area, had sent me a newspaper article about Tim’s operation. Later I attended a GAL Convention. I’m indebted to the GAL for being an inspiration for me as an instrument maker — it gives proof that it can be done.

I got my start in the violin field by way of a friend in Seattle named Bill Tafoya, who ran a guitar shop there. In 1973 I told him that I wanted to make guitars. He suggested that I go in the direction of violins instead, and he thought I should contact David Saunders, who had a violin making shop on Queen Anne Hill. I called David, and although he was not taking apprentices at that time, he connected me with Peter Prier, who was just starting the Violin Making School of America in Salt Lake City. I called Peter in 1973 and finally started at the Violin Making School in 1978. I graduated in 1982.

Violin Bridge Holder

Violin Bridge Holder

Thanks to George Manno for some feedback on his experience with bridge tuning. Bridges on good violins do tend to be quite similar, but I still like to work them up individually. And he is certainly right about fitting the feet!

One dimension he seems to have left out is the thickness of the feet at the bottom of the bridge, generally given as 4.5MM (3/16"). If this is too heavy it can make the instrument sound “closed.” If you don’t want to thin it anymore a bit of wood can be removed from the end of the leg without affecting the stiffness too much.
