Colordaptor questions

[Phil]

I'm not sure if this is the correct forum for this question, but here it is: I would like to build a colordaptor. Does anyone know where I can find appropriate color filter plastic for building a color wheel? The delay line apparently needs some space between turns, i.e., it can't be close wound. Would it be possible to use a delay line from an early color set? If so does anyone have one they would be willing to sell. The instructions give a pitch setting for winding one of these on a lathe, but even if I had such a thing I would have no idea how to set it up to do this. If a delay line from an tube color set wouldn't work, is there anyone on the list who understands these instructions for winding one and would be willing to wind one for me, for some price?
Thanks,
Phil
