Tom (and all),
>From personal experience with a very similar restoration project, I found
that clear hot glue works great to "renew" the plastic spacing on an air
dielectric coil. Don't use the hot clue with pretty metal flakes that
crafters like, make sure it is the clear sticks.

Subject: [TowerTalk] Johnson Matchbox coil
I have a 275 watt Matchbox antenna tuner that is in really nice shape, with
a blown bandswitch. I purchased another 'junker' from a guy, and really,
the only thing wrong with it is the plastic on the coil has disintegrated
and it is kinda dirty. It looks like it could be repaired by making some
plastic spacers of some sort.
What would be the best way to reinforce the turns in the coil? I was
wondering about super-glue. Will it hold up in an RF environment?
Other than the coil being sprung, it isn't in too bad of shape. I'd kinda
like to repair it instead of taking the switch out and putting it in the
