Variable inductor, DIY?
This is the answer:

I'd like to build a variable inductor with what I have around my shop
(lots
of bits n' pieces, but no cores). I need it to work in the area of 20-30
mH,
1A, 25-30 KHz.
Is this something do-able? Is there something available off-the-shelf?
Suggestions of how to go about it would be greatly appreciated.
