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.
Here is a terrific little saw handle that takes Sawzall blades. It comes with an array of blades, including the dangerously sharp flush-cut and rather dodgy drywall blades, and a few others that I've long since used up, but it will fit any Sawzall blade. But what really makes this thing great is when I started making my own blades - all the small ones along the right. I cut these from much larger Sawzall blades that I bought, using an angle grinder, and shaping them on the bench grinder. Sawzall blades all cut on the pull stroke, but as you can see, two of these blades cut on the push stroke, because I cut them reversed from the parent blade. The tangs are easy to make. Push blades are good for cutting through finished or laminated surfaces. These little blades give me a hand-held jigsaw, very useful for many loothery tasks. This saw is a Craftsman, so you better hustle on down to your local Sears and get one before it closes. Mine is on the death list. StewMac should pick up this idea.
