Hi Dan,

I dont know if you will call this half-a**ed but it works exellent for my 
coils.  Take some 4" ( or whatever you want) diameter black flexible drain 
pipe.  Form a toroid of whatever size you want.  Tape the ends together.  
Then wrape the whole thing in duct tape to help get rid of the dips in the 
corrigation.  Then when its all covered, cover it again with aluminum tape 
strips.  My 4" tall x 14" diameter toroid has no problem putting out 1 or 2 
arcs of 30" or so.  If you want bigger arcs go with a 5" or 6" pipe, and a 
resonable outer diameter as to not load the coil down to where it cant be 
tuned.  But 4" is what was handy, and its big enough to build up arcs in the 
30-36" range fairly well.  You may have already seen this, but maybe you 
dont know that it really makes a good performer, for very little money.  Im 
sure that you are looking for a good looker too, but this doesnt look too 
bad.

Steve Ward.
