Variable inductor, DIY?

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.

How about using a very low-ohmic wire-wound pot? OK. Q will not be
brilliant, but in these applications you may get away with it
