JC:
I looked around and found nothing in the way of wire locally as well.
Unless I ordered through JCH wire and cable (local place here)  they
wanted a tone of cash for it.

But I found the wire is pretty cheap at McMaster Carr (McMaster-dot-com).
Go to their web site and in the search window type in "magnet wire"
then on the right side frame scroll to the bottom.

I paid $16.36 for my 3000' spool of #26 wire.  Their online catalog
rocks!! IMO.

Oh yeah I called before I ordered it thinking the shipping would be
high.  Turns out it would be about 5 bucks.  And I ordered other stuff
with it.

Hope that helps

John, checked out your design. Looks really good and easy to build. I
have
one question, however. And it is a generic question too. For a 12kv, 30
ma,
60 hz NST, the capacitor works out to be .0066uf. Yet you and alot of
other
designs use much bigger caps. How can you still tune? With the program I
am
using for design, changing the cap from .006 to something larger meshes
up
all the parameters making it impossible for me to still use a 4"
diameter
secondary with a 5:1 aspect and still tune it. Maybe I need to play with

the numbers some more...

I did go to Home Depot and Lowes and I must say I am very disappointed
with
their wire selection. I wanted to get some 10 gauge solid wire to
emulate
what you did and they had none. All I was able to get was 8 gauge bare,
solid wire. Not a problem really. But no one had any wire smaller than
18
gauge, no 22, 24, 26, 28, no nothing. So I need to look around the area
some more. I did pick up a long 12' PVC drainage pipe for about $5. That

wasn't bad. I also picked up 2 end caps for 94 cents for the pvc so I
can
make a rig to spill it when I do wind the wire on it.

JC,

You may want to check out my TT-42 type coil at my website
which uses a 12/30 NST and a 4.25" dia secondary and gives
42" sparks.   There's a link there to John Morawa's TC which is
prettier than mine I must say, and it uses 1/4" tubing on the primary.
