My project involved working on broken guitar pickups. Now, I don't want to take credit for thinking up the idea for this. I read about how to do this on the Seymour Duncan users forum. What happened was that a forum member took apart a 59 model pickup and a Custom model pickup. He took a coil from each of them, and put together a pickup combining one coil of the 59, and one coil of the Custom. He then called this pickup, "The 59 Custom."
So I happened to have a broken Seymour Duncan Custom pickup, and a Dimarzio FRED pickup. However, I was lucky in that, I had a working slug side of the Custom. The Dimarzio FRED has adjustable pole pieces on both sides, and one of the sides was still working.
So I decided to make a new pickup by combining both working coils. This sounds easy, but there are a few steps. First I had to figure out the start and stop of each coil. Seymour Duncan and Dimarzio have different color codes so I had to keep them straight.
I'll go over this next part pretty quick, but I had to work with some very fine wires, and make sure I didn't burn up the coil windings. I also used some heat shrink tubing to protect the where the wires came off the pickup and connected to outgoing wires. That worked really well. I also bought some cloth tape from Stew-Mac to wrap around the pickup. That was one of my better purchases.
I also changed the hex screws on the Dimarzio coil to Phillips head screws. The hex screws were extremely rusted. I also used a polished Alnico 2 bar magnet. Here's what it looked like after I attached all the wires and put the pickup back together.
