I'm not a builder, only hanging out hoping for osmosis to kick in.
But I did burn holes in myself with transformers before I could spell em

That's a hot idea of simplistic flexibility.

If not for the desired aim, then surely for some form of optimization

p.s. Really I'm more of a divide-and-control thinker/solver, but the
idea reminded meself too of a sorting algorithm where two choices in a
list are made to divide the section that is more-correct into a thirds,
rather than binary halves.
And if you want to balance against a floating, untapped virtual center
point somewhere in a long winding, then what better principle than to
balance the physical lengths with adjustable taps as a first order
calibration before the machine is test-worthy. I love the new trick!
Like a new programming pattern for a coder :) Here me purrr.

Hi All
With a bipola coil would having 2 movable tap point work for changing
the coupling ?
Say the coil need 5 turns to be in tune, you could built the primary
with 10 turns and you could move the inner and outer taps points in or
out but still keeping the 5 turns needed to keep the coil in tune, the
inner and outer turns passed the tap point would be electrialy dead so
to speak.
Thoughts on this one guys.

Hi Kurt,
Splitting and separating the secondary seems like a great way to vary
the
coupling, but one must also bear in mind that doing that will vary
the Lsec
inductance and tuning. I can't think of a way to vary only the
coupling on
a bipolar coil, but I have never built one.

...just my 2 cents: cutting the bipolar secondary in 2 independently
movable
halfs could enable the control of the coupling (see the ASCII-sketch):
