I built a rudimentary coil with two crown washers that I had.
When I rotated the rings, they did make the "hourglass" shape.
Two rings slotted to maintain the winding spacing
could be slid over a slightly smaller tube instead.
It wouldn't be perfect, the outer coil lacing
would come close to the inner lacing a bit.
But the only point to this was to try different angles.
If something quite obvious arouse during tests,
than an actual coil form could then be fashioned.
the outer secondary would still be close enough too.
I hope I waited long enough that
the pissing contest is over...
It aint a SM TPU, thats established,
but this is still something to look into.
Isn' it?
I look forward to exchanging useful ideas,
and watching some progress now.
Even a notched tube like FatBird's PVC coupler
could be used after you find the rough angle.
Just count the number of offset edge slots
that are closest to the angle desired.
You wouldn't need a new form every time
just rewind it (Again) at the newer angle.

On an off-topic note, I need to ask something.
The last few days when I go to post
one or two words are replace by a capital "A".
I didn't think anything of it until I saw it in other posts.
Like my quote of Talath above as example.
I had to replace an "A" with the word "coil"
because he has one in his post.
It only seems to happen if I use the "Quote" button.
Whats up with that ?
