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?
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.
