How to make the changer on a steel guitar?

1 comment

I understand the basic idea of a changer in a steel guitar but i have looked at a lot of diagrams and i am still a little unsure one question is how many pieces is it i know it lowers and raises.My next question what kind of time am i looking at using a milling machine to make one no CNC or anything like that just a regular old milling machine.

The changer to a pedal steel guitar is fairly complex, and far too complicated to sufficiently describe here. Basically, each string is attached to a ‘finger’ which can rock forward or back. All the fingers are mounted side-by-side on a rod…similar to coat hangers in the closet. At it’s most primitive (like a Sho-Bud Maverick) you pull on the finger and the string raises.

There are two basic types….”all-pull” and “push-pull” and a lot of variation within each type. If you haven’t actually seen the mechanism up close, you’ll have a hard time understanding how it works, much less trying to machine your own. The more complicated changers are capable of multiple raises and lowers on each string. In addition to the fingers, you need to make adjustable stops so the pulls can be tuned. Then there are the levers, rods, cross bars and bell-cranks which operate the pedals and levers.
