Shop Made Router/Scratch Gauge for Making Guitar Binding Ledges, Part 2

My early bridges...were made entirely by hand using the smoothing plane, the hand saw, chisels and a scratching gauge...

Jose Romanillos, Making a Spanish Guitar, 2013


Some one asked me if I could supply plans to make a scratching gauge, as much as I would like to, I don't have the time and I am trying to stay away from making this a "how-to" blog. There are many blogs/websites out there in the Internet hinterland that show you how to make a guitar, I don't want to compete them.

All I want to do is make guitars and sell them.

Here is a short photo essay of my scratch gauge, a person should be able to make a copy of one by looking at these photos.

And, you should look at Roy Underhill's books on how to make marking gauges, and click here to visit Adam Cherubini's marking gauge PDF.

And, and, you should read the books on guitar making that I have listed elsewhere in this blog, just go to the search book and enter in "the best books on guitar making".

To make my gauge you will also need a 1/4-20 tap to cut the threads for the brass screw which is available from Rockler.








By tapering the fence, starting a 3/32 of an inch from hole for the arm, you can compensate for the arching of the guitar back. See the last photo.




I made the shaft a "V" shape to compensate for the curves of the side.



Use a piece from an old card scraper to make the router tooth.




Leave the arm long to register against the guitar sides.

Experiment and have fun!

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…

The New Workshop: New Roof, Snow, Rain, Sub-zero Temperatures

A snowflake is one of God's most fragile creations, but look what they can do when they stick together!

Author Unknown


Cold weather and snow delayed me in getting down the corrugate tin roofing on the new workshop. January 3rd proved to be a day of snow flurries and sunshine which at least allowed me to install the roofing. Then it snowed six inches.


The temperature fell to -5 degrees Fahrenheit and it kept snowing...


...until there was 22 inches of snow on the ground. And the temperature fell some more to register -14 degrees Fahrenheit on the thermometer.



Yesterday, the temps warmed up to 36 degrees Fahrenheit with the wind gusting up to 50 mph and we lost power for about two hours.

This morning we woke up to rain and warmer weather. I am very glad that I got the new workshop "dried in" before all this snow fell.



The high reached 40 degrees today with rain and snow flurries, there is a good six inches of slush underneath all the snow. No wind to speak of today, though…

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…
