Waht type of ballast are you trying to make? There are some very large 
ballasts in those long flourescent tube circuts. I don't know how suitable 
they are for current limiting on xfmrs. If you are looking at winding your 
own, try making a bobbin out of thick oaktag stock. Glue it all together and 
wind and put it on the core and good luck!
