Home-made coil winder

In my home-made coil winder I used 1/2 inch bronze bushings along with all-thread for the winder (I also have a smaller 3/8). The "cam" that actuates the pocket calculator is a 1/2 inch hex nut with 5 of the 6 points ground off. On the wire measuring device, I installed a small 1/4" all-thread into the handle of the tension lever so that the amount of spring tension between the two "wheels" could be adjusted allowing me too pull small mag-wire without breaking it. On my first coil I wound a bifilar coil with 1500 feet (4000 turns) of AWG-28 along with 4000 turns of AWG-42 wire (so small it's hard to even see). Took about an hour to fill the coil. Then I used CPVC plastic pipe 1/2 in. and 3/4 in. for "bushings" for the center core of the spools, as well as the "end" spacers for the feed end to keep that spool centered on the shaft.

That pocket calculator idea is funny and clever. I like it.
