 I can't seem to figure out a way to build a good solid primary tap
 connection that isn't so bulky as to nearly short the 1/4" gap between
 turns.  How heavy does the tap need to be?  It seems silly (to my
 limited intuition - this is my first coil) to have some skimpy clip
 device on such a heavy coil (1/4" tubing).  Also, how heavy should the
 wire that leads to the tap be?  If possible, would it be OK to just use
 1/4" copper tubing for the whole circuit, i.e. primary to cap, cap to
 spark gap, and spark gap to primary tap, all the same 1/4" tubing?
 
 
    Thanks,

Bill,

You can certainly use the .25" dia copper tubing for interconnecting the 
primary circuit components.  One of my coils is built like that.  I do use a 
heavy multi strand conductor for the primary tap lead since it needs to be 
flexible.  Both coils use a spring loaded clamp with a short piece of copper 
tubing cut in two lengthwise and soldered to the clamps to nicely fit on to 
the primary tubing.
