Wooden Straight Edges

It is not advisable and can even be dangerous, to entrust someone else with the search for a fiancee, the purchase of a pair of shoes or the choice of a guitar.

Jose Ramirez III, Things about the Guitar, 1990




I didn't get everything done today that I wanted to get done, but I did get started on a few things.

After morning chores, I took the dogs for a walk through our wonderful backyard, which is part of Arapahoe National Forest, and then started making legs for a router table. I have about ten windows (6-9 pane) to make before the end of December and I am not about to plane all the muntins, rails and stiles by hand, I have an expensive router bit for that.

I got the legs glued up, went for a 2.5 mile run and had lunch. The afternoon, I thought, was going to be dedicated to working on a copy of a 1968 Hernandez y Aguado classical guitar, click here for a post on that guitar, I need to thickness the fret board and glue it onto the neck.

First thing I wanted to do was to check to make sure the gluing surface of the neck was still straight, and, as usual, I once again discovered that my 24 inch long Lee Valley straight edge is too long to check the neck. One end of the straight edge ends up on the guitar body which has dome to it so the straight edge won't sit flat. Duh.



The answer was to make a straight edge. If you don't already have Chris Schwarz's article on how to make such a beast, click here and take a gander at how to make a wooden straight edge.

I wanted to use some mahogany that I have, but it isn't quartered well enough. Once again, it was California laurel to the rescue.





The straight edge that I needed most was this one - 16 inches long to check where the fret board will sit. I should have made it 17 to 17 1/2 inches long.





I had a 10 inch piece left over which will be perfect for checking the other side of the neck.





I love California laurel, I wish had some more. It has a wonderful smell, is very easy to work with and makes incredible sounding guitars. I suppose I ought to order a few laurel boards from Gilmer Wood or Northwest Timber.

The fret board will have to wait until next weekend, tomorrow is back to work at my day job.



Here's another YouTube of Leonora Spangenberger.

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's Scale Length, Your Hand Size and a Chart

I will cite the case of a marvelous concert player, a Japanese lady who is barely 5 ft. tall and with hands that are real miniatures. She plays a 664 mm 10 string guitar and demanded that I build this guitar with an action 1 mm higher than normal, which she handles with incredible ease. This is serious study!


Jose Ramirez III, Things About the Guitar, 1990




Here is the hand size and scale length that I found on the forum at delcamp.com.

Thumb tip to pinky tip span of 250+ 664mm scale length
Thumb tip to pinky tip span of 230 to 250 656mm scale length
Thumb tip to pinky tip span of 210 to 230 650mm scale length
Thumb tip to pinky tip span of 190 to 210 640mm scale length
Thumb tip to pinky tip span of 170 to 190 630mm scale length
Thumb tip to pinky tip span of below 170 615mm scale length



Here is my flexible imperial/metric ruler.




Here is my hand properly placed on the flexible imperial/metric ruler.




Today my reach from little finger to thumb is 240mm. I should more or less be playing a…
