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.
