It not only works, but works GREAT! I'm a step behind you on this :) I'm 
working on a 12" twin system and it will have a ribbon primary.

Bill Wysock and the guys at www.ttr-dot-com have known this for decades, take a 
look at their BIG coils. Almost every coil that TTR makes has either a 
helical (think spring) or a ribbon primary.

Btw, one of the largest coils on earth, the 13-M uses a ribbon primary. 
Electrum (www.lod-dot-com), the other giant coil, uses a helical primary.

If you do build one, I reccomend you closely study how the guys at TTR mount 
theirs. The coilform is crucial to making them function correctly and be 
nice and round.


Have fun!
