Hi John,

Your coil will work perfectly fine!!  I like # 24 for spark gap coils 
and #28 for solid-state stuff.  (it's been about two years since I 
have even run a spark gap coil now =:O)  But as long as your coil is 
not wildly out of the norm, it will be just fine.  Don't worry at all 
about little air gaps.

You should spray it with clear polyurethane or something just to 
"lock" the windings in place unless you are going to do that anyway.

Cheers,

        Terry
