Santos Hernandez Style Classic Guitar - Late Night Work

The classic guitar is a difficult and demanding instrument. There are no short cuts.


Vladimir Bobri, The Segovia Technique, 1972



I got back to work on a close copy of a 1930 Santos Hernandez guitar yesterday by glueing on the so called "fan bracing", as you will notice, these braces are nearly parallel to each other, and the transverse braces to the top.

When I got up this morning I un-cinched the clamps and discovered that the top had a definite twist to it.

Hmm. Bad glue up technique on my part and the humidity had dropped from 39% to 29% overnight, not good for a guitar top or my nerves. That is the problem with working at lutherie this time of the year, especially during and right after a big snow storm, the relative humidity can really drop. The humidifier can't keep up.



I needed to run errands this morning, when I got back I split the transverse braces off the top and shaved the remnants down to the glue.

Then I made new braces.

I clamped the top down to the work board and glued on transverse brace number one, once the glue was set then I glued on the wide flat brace closest to the neck.

After that, time to walk the dogs and make dinner.




The brace below the sound hole has a 1/16th of an inch arch to it to help dome the top.

Doming the top gives the guitar a real voice, one that has volume and character. It's like a drum head, you want it tensioned to be loud.

When I glue this brace on I usually use two slats as backing cauls and a C clamp at each end. Then I push two shims in between the slats to force the top to the brace and the glue.

This action is what can cause twisting.

Tonight, I used the slats, but I started by clamping in the middle, the a C clamp on each side of the Quik Grip, and continued on down to the ends of the brace.

I couldn't see any twisting or winding to the top.




Then it was a little trim work on some laminated all walnut cam clamps, which I should work on tomorrow..




and then double check the neck. If all goes well I can bend the sides tomorrow and attach the top to the neck.




Now it's bed time.

It's not that late, maybe nine o'clock, but I never could work late into the night, even in college I couldn't work on term papers past 11pm. Back then I had an electric typewriter that could erase the last ten words that you typed, I thought I was lucky to have such a beast.

Still, I have a jar full of incense cedar bodied pencils that are more fun to use than any computer.

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…
