Building a Guitar

This week I’m learning how to build an electric guitar–from scratch (or almost). Tom Singer, a professor in design and manufacturing at Sinclair Community College in Dayton, Ohio, is the lead on an NSF funded project to bring guitar building into schools.

I may have a tin ear when it comes to music, but there is quite the interest in guitar playing at the Fulton School at the moment–all the way from the elementary kids to the high schoolers–so I thought it would be a good catch-the-imagination mechanism for use in math and science.

Bodies

First we got to choose a guitar body. The guitarbuilding team had a fair collection of guitar shapes for the group in the workshop to choose from. The shapes are cut from 1.75 inch thick woo. To get the elegant layered patterns you see above, they laminate about half a dozen different types of wood. This may make for beautiful guitars, but the different densities and hardnesses of the wood have to be considered when working with them. The darker colored woods in the guitar body above were much harder to shave and sand than the lighter colored material.

Note to self: Indeed, if I remember to get hold of some scrap pieces of the different woods, I can probably make up a nice density measuring project. Indeed, it would be nice to have students graph the relationship between density and hardness. Wood hardness is measured on the Janka scale. I suspect there is a positive relationship, but I’d like to see if we could determine the shape of the curve.

Not all of the guitar bodies are beautiful laminates, however. Some, of a single type of wood, are the best candidates for painting. Others are hollowed out, and can be played acoustically as well as plugged in.

Neck and Fretboard

Today I learned what a fretboard is. Apparently it’s a separate piece with the gradational markings that’s attached to the neck.

The necks were all of maple, if I remember correctly, but the fretboards were made of different types of wood. Each was a single piece of wood, but the wood’s hardness and affects the “brightness” of the sound produced by the guitar.

So now it’s time to sculpt and sand the body, and put all the pieces together.
