Cool, I've been cleaning things up and looking to build a winder for
this project. i have some "GLYPTAL" HV transformer kits with epoxy and
fiberglass cloth with tape. I'm thinking maybe layers between windings?

 I have three dental x-ray

Are they butted end to end and the primary split with opposing winding
directions?

 Beneath each HV coil is a primary.

Will do. I'm assuming that i am not to use any gapping of the two core
sections? Would it be feasible to wind many secondary bobbins, each one
rather narrow (kinda like the spools that fishing line come on) so i
could add more to get higher and higher primary-secondary ratio's?

Even though these cores are more like big "U"'s, I should think of them
as EI cores?
