Building a Bridge with a Stanley No.192 Plane

The bridge of a guitar as we know it today is a relatively modern invention consolidated by Torres, although he was not the inventor.

Jose L. Romanillos, Antonio de Torres, 1995


Many people don't know how much work is involved in constructing a guitar bridge, I know for most classical guitarists it is simply an anchor point for the guitar's strings.



I arch the bottom of the bridge to match the guitar sound board's doming, cut a channel for the saddle to sit in and I make a tie block for the strings.

The tie block gets covered with a piece of mother of pearl, this protects the tie block from string wear and gives the guitar a bit of bling.

Since I am making a fairly close copy of a Hernandez y Aguado bridge, the tie block is sloped towards the saddle slot, this was original done to increase the breaking angle of the strings over the bridge. This helps increase the overtones in the guitar. Compare that with a modern flamenco guitar bridge and you will see the string "breaking angle" is very, very shallow, the string goes almost straight from the tie block to the saddle.



I souped up the blade on my grandfather's Stanley No.192 rabbet plane and it works wonders in cutting out a rabbet for the tie block overlay.



It would be nice to close up the mouth of this plane just a little, but if I do my job of properly sharpening this Sweetheart Era blade it performs with perfect aplomb.



The Rocklite Ebano bridge with its new MOP tie block overlay. I put a bit of hide glue on the tie block, dry it with a heat gun, clamp the MOP onto it and then run some CA glue along the edges.

Tomorrow is the day from drilling the string holes in both bridges, then the final shaping and carefully stowing away the bridges so they will not become damaged.

Please bear with me as I find a new template for my blog, I want the blog to be easy read and search.

Here's a video of a brilliant young guitarist from Australia, Stephanie Jones!

How to Make a Traditional Froe Mallet

What holds the Holy of the Holies, what did Brahma become? Wood. Why will aspen always tremble? For the nails driven into the cross. What makes the color of wood? The soil it tastes. Cradle, fiddle, coffin, bed: wood is a column of earth made ambitious by light, and made of beauty by the rain.

Kim R. Stafford, Having Everything Right, 1986.

Rive, verb, to split
Shake, noun, a split in a piece wood. (Heart shake, ring shake)
Shake, verb, (Middle English), to split.

I know I should have been in the studio working on my back log of guitars, but the day was so nice and warm with a tall blue canopy, I couldn't stay inside. I decided that I needed to make a proper froe mallet. This style of mallet is traditional to northeastern California, primarily Tehama (where I'm from), Butte, Shasta and Plumas counties where making shingles by hand from sugar pines was an industry. I don't know if it was used in any other region along the Pacific Rim, other parts of the United States or even o…

Basic Hand Tool Kit for Making a Classical Guitar, Revised

Ours is really a simple craft.

James Krenov, The Impractical Cabinetmaker, 1979


So, you want to build a guitar.

Since the original post, Basic Hand Tool Kit for Guitar Making, click here to see it, is the most popular post on this blog, I thought I would revisit it and adjust it to what I am using now to make a classical guitar.

The first thing I recommend doing is to buy or borrow copies of the following books:

Guitar Making: Tradition and Technology, by William Cumpiano and Jonathan Natelson
Making Master Guitars, by Roy Courtnall
The Guitar Maker's Workshop, by Rik Middleton

These are required reading before you begin making a guitar.

Also required reading are these books by Roy Underhill:

The Woodwright's Shop
The Woodwright's Companion
The Woodwright's Workbench
The Woodwright's Apprentice


Why these books by Mr. Underhill? You will learn valuable wood working techniques if you make any of his projects. The dovetail joints used to join a drawer together are far mor…

The Guitar Maker's Backsaw for Cutting Fret Slots

The overall correct process of placing frets in a guitar fingerboard ("fretting"), is far less straight forward than most people believe. A perfect job, for perfect playability, requires some careful preparation.

Anthony Lintner, guitar maker



Twenty five years ago, I bought my first fretting saw from Luthiers Mercantile. It was made in Germany and had a straight handle on it, basically it was a gent's saw.

First thing I did to the saw was to take off the straight handle and make a nice handle for it from some wonderful Claro walnut that came from a Cottonwood Creek bottom wild grown walnut. I used it to cut fret slots in dulcimer and classical guitar fret boards. The saw served me well for several years until I made the mistake of cutting some brass with it.

Well, I never did get around to sharpening the thing.

The blade is .015 of an inch thick with the teeth set at .022-.023 of an inch. I think it has 22 teeth per inch. It is a great saw and I was very sad to see that…
