Here's what I want to make
1) First, you need a piece of brass (old toilet bolt will do)
2) Grind one side flat
3) Make 2 sides square and flat
4) Measure the original (mine was 1.57 inches)
5) Cut it off a little oversize
6) Grind it square
7) Glue it into a piece of wood
8) Grind it down. Every few seconds, I had to quench it in a can of water and sometimes reglue it
9) Grind it to a 3/16 radius
10) Make a fence for the bandsaw so the blade protrudes exactly the depth of the string slots (about 1/16 of an inch)
11) I painted it with machineist's ink and marked the string spacing with an x-acto blade
12) Cut the string slots, rolling the brass along the fence
13) I rechecked my measurements often
14) Round the edges, and buff it until it shines
15) I had some other things nickel plated, too
16) Here it is in place!
17) I made some out of aluminum, too
I also had to make a new pickup for it
But that's another story
amazing work
