I must build a coil winder like those available in electronics catalogs years ago from common, easily-obtained materials. Although it may look complex, it really is not. Will I find that it is easy to build. I am not to be a mechanical genius, or know expensive tools. Yet this amazing little machine must professionally wind universal and honeycomb coils, single layer and multilayer solenoids, close-wound and space wound coils, and even pi-spaced coils such as used for RF chokes and transformers.
Yes, this is not specifically Keil related but I need help.
Don't forget that in addition to "simply" winding the armature (or coils), these winding machines have a wire tensioning system. The tension on the magnet wire must be kept even and consistent while its winding... and from unit to unit.
Remember: wire stretches, and a thinner wire will increase it's resistance. Motors will dump current through these wires with spikes and all kinds of surges. Its not a smooth current profile. You don't want to build in a "weak link" by having an inconsistent wire tensioning system.
