experimented with using a slinky as a loading coil for a "portable"

dozen or so members tried it. With, as you'd expect, mixed results.

because it needs a form to keep the coil stable.

Would sheets of plastic inserted between the coils to prevent contact
plus an overall clamp to maintain shape do the trick? Once done, it
could be 'set and forget'...
