One of the fun things about building electric guitars is wiring them up. Factory wiring tends to be simple, minimizing the amount of fussy handwork required. Many manufacturers keep strictly to 'classic' designs, seldom if ever changing anything. These designs are generally simplistic, often crude or even stupid, and sometimes outright flawed. There is no need for you to do this. I don't. Here are some of the things I have done over the years. I don't claim to have invented any of this, although some of these schematics I have never seen anywhere else, and had to derive them myself.
After making a muddle of things with a razor blade and several other implements that proved to be less than satisfactory, I decided I needed to have the right tool - something roughly pencil-sized that can be handled with precision and ease, with a proper scraper edge. I took a look at StewMac, and found their binding scraper - exactly what I was thinking of. But with shipping, it would cost $15, and I'd have to wait a week for it, and after all, it's just a piece of steel. So I started thinking and remembered I have some 1/2" steel binding strap material. This is the stuff that is used around very large heavy boxes. It is a fairly hard and springy type of steel that would probably make a good tool. So I got busy in the shop and made three scrapers.
