I came up with this idea to make a tiny antenna tuner. Thought maybe I
could remove the wire on a rheostat and rewind it with copper wire so I
can make a long wire antenna tuner .

Check a back issues of QST. Someone did it (miracal antenna)
in a construction article.

They wrapped a ferrite toroid (large one) and use the wiper and
bearing from a Wire wound rheostat to select taps on it. I tried it
for a very small Pi tuner and it was decent.
