Since a picture is worth a thousand words, I'll spare you the bandwidth.
Just go to the Tesla Coil Web Ring:
http://nav.webring.yahoo-dot-com/hub?ring=TeslaRing&list
and look at how everyone else does it.  Mine is illustrated at:

The spacing between turns is not at all critical.  The only
consideration is that whatever method you use to make the "tap"
connection should not short to the next turn.  Using too wide a spacing
will lower the coupling and require more turns and tubing for the same
inductance.  Most of us use about a 1/4" space between turns. (1/2"
center-center w/ .25" tubing)

How exactly does one build the primary coil? How do I calculate the
spacing
positions for my copper tubing?

Thanks,
Patrick.
