But that would have produced a "vertical" loop of constant "diameter". How
did you get it to lie down, and vary in diameter?

Yeah, it could have. I used them as the starting form for the first
loop. Subsequent turns were laid down progressively around the wire,
not the coil form. Hence my comment about using CA glue to spot glue
the wire in place as I wound the turns.
