Robert, all,

I would use a 4" x 20" form (or similar) for one 15/30 NST.
In an optimal design, this can give 45" of spark output.

For (3) NST's you could use maybe a 6" x 28" form or
something similar.

You could even start with the 6" x 28" form and use it for
the one 15/30, so you don't have to bother building two coils.  

Happy New Year Everyone !!
John
