I have tried this and it seems to work fine but then again I wouldn't know the
difference because I have only built one small coil and this is the only
primary arrangement I have used. I usually keep the coupling as close as
possible because it is a very small coil and I get better results with it on
the closest coupling. I don't see any reason why it wouldn't work on a larger
coil. Just be sure to use a tap connector that covers a fair amount of surface
area on the primary coil.

I had an idea, for easy changing of coupling. What if, say you had a
15-turn pri. and tapped it at 10. Why couldn't you build a 20 turn pri.,
tap the outer turn at 5 in from the out side (actually 15) and the inner
tap at 5 from the inside. then, when ever you wanted to change the
coupling, you would just move both taps at the same time, and you could
still change how many turns you have. It would look like this:

| | | | *| | | | | | | | | | | *| | | | | O
outer tap inner tap secondary
