	I haven't seen a reply, soooooooo
 
> is it possible to make a coil without the secondary?

	In a word: Nope.

	Really Large coils, Colorado Springs to present, tend to
	use a very low secondary, of large diameter.  This is
	impractical for most builders, but has (it seems) some
	advantages,  (L/R ratio....)if the room is available.

	eg:
	Tesla's Colorado Springs coil (if memory serves) had 
	a secondary 10s of feet in diameter and 6-8 feet high.

	The primary was (usually) a single turn, and did not show
	in the pix, mostly.
