On the Custom Lap Steel pickups the coil had to be wound off center on the bobbin. Spacers of wood or plastic was used to help keep the materials from warping over time. The Direct String Pickups use two Vulcanized fibre flatwork and often a clear vinyl plastic, computer cards or thin fibre board was used for the center of the bobbin.

K & F Lap Steels 7,522 Turns 42 PE rectangular pickup Below are some winding specs for a few “Direct String Pickups†where the strings go through the pickup. Each end of the pickup uses a sand cast Alnico magnet with the same polarity facing up on each end. The front side of the shells or casing are notched between each string to focus the magnet field to the strings. The pickups looked rectangular from the top. The strings were actually through the center of the coil. The case hardening keeps the string from cutting into the edge of the material. The pickup used two Alnico bar magnets and held in place by two fabricated case hardened steel shells and the bottom shell or case would support the string and guide it through the cylindrical tubes. The bobbin consisted of a Vulcanized bobbin with 6 tubes in which the strings would go through without touching the walls of the cylinders. In Leo’s and “Doc†Kauffman’s early patent number 2,455,575 filed on Septemand granted on Decemthere are several components. There were several types of pickups used on K & F and Fender lap steels. What kind of pickups are used on older Fender Lap Steels? Heres another of Seymour's posts on theseģ28.

I don't think he would post disinformation, and I have not changed it, so maybe it will help you out, and HF equals Heavy Formvar as used on Strat pickups and lots of other Fender pickups as you can see below. I copy pasted saved the following from an Ask Seymour (Duncan of course) webpage from about 15 years ago I think.
