When I did my rewind, I wound three coils at once for a concentric wind pole. This introduces a few extra problems with trying to wiggle the coils into the stator slots.(the problems of slot fill verses terminating all the coils ends... I felt slot fill for three joined coils was the lesser evil)

I had difficulty with the first coil of the three, worse with the second and didn't bother even starting the third until I came up with a better way.

What I found was the greatest help was to get 2 pieces of your slot paper... say 2"  wide x the length of the stator, and tape them to the inside of the stator so that only the slots you were currently interested in are exposed (dont worry about the inner slots between, just the 2 slots your working on and outside them.)

Your coil will be too wide to bother falling into the inner slots.

When the paper is in place, put the coil inside the stator, and the wires will almost fall into the slots because there is nowhere else to go or drop into.

Once I discovered this, it took no more than 2-3 mins to put 75turn coils into their respective slots, and was just as easy for the last coil as the first.

Without those pieces of tape and paper, it was absolute hell, and maybe 10-15mins per slot. The difference in ease is astronomic.

go for it
