   I admire your determination! I have a screw-cutting lathe which is ideal   
   for this kind of thing. I can just stand there with a reel of wire   
   putting a little tension on it as it gets unwound and a short time later,   
   a *perfectly* spaced coil emerges.   
   The OP could also try microwave oven transformers. He'd have to re-wind   
   one as they're not much use as they come. But the *are* next to free to   
   come by from your local recycling centre and ideal for experimenting with.
