It shouldn't make much difference if you simply use the thickness of
the ribbon in place of the diameter of the wire, even if the result
isn't spot-on, you'll be plenty close enough to get sparks off the
topload.  Then you can do the final tuning by the tried and tested
try-it-and-see routine.  I used brass "boiler band" from a model
engineering supplier (half inch by ~0,035") and had no problems with a
*very* crude guesstimate.
