The D'Andrea company was founded in 1922 by Luigi D'Andrea in New York, who started out by making mandolin and guitar picks out of tortoise shell colored cellulose nitrate plastic. While guitar picks are still the mainstay of D'Andrea, they now offer a range of guitar parts and accessories as well as KSD basses.

Make the bearings and pipe supports



The JGRO design achieves linear motion using bearings running along pipes. The bearings are made from standard skateboard bearings bolted to aluminium angle. There are 3 pairs of bearings, a pair for each axis of motion, and each pair a different size. These bearings run along metal pipes, 0.84 inch diameter gas pipes for the Z (up and down) axis and the X (side to side) axis. I can't find these gas pipes in the UK so I am using cold rolled steel tube for the time being. The Y axis uses thicker 1.3 inch diameter gas pipe, which is not easily available in the UK.

Build a home made CNC machine (JGRO router)


This project describes how to make a CNC (computer numerical control) machine that could be used to make guitar parts. CNC may not always be the most efficient way to make guitar parts (a band saw and pin router is often the most sensible way to do guitar woodwork) but they are a flexible way to convert complicated 3D computer designs into reality. A good discussion about the role of CNC in guitar making was posted over at project guitar .

Graph Tech

The GraphTech brand was founded by Dave Dunwoodie. As a guitarist Dunwoodie was troubled by string binding on traditional guitar nuts.

"I went to do my first big “wang” and went totally out of tune" Dave says. "I couldn't use the guitar for stage work at all".

Dave began experimenting with a variety of composite guitar nuts designed to eliminate string binding before engineering the world’s first self-lubricating nut, a formula that is 500% slipperier than graphite.
