[Elecraft] Frozen Variable Inductors.

[Gary Thomas]

Hi. Im building the xv222. There are three can type
variable inductors supplied for use in the IF.
(L15-17). Manual instructs to "exercise" the cores
before insertion using the supplied shaft. They are
not simply tight they are frozen near the top of the
form. Any suggestions on how to loosen the cores
without damaging them. I already see what appears to
be a hairline crack in one of the cores which may have
been caused by trying to turn the frozen core. Any
help is appreciated.. 73 Gary aa1ue
