[Hallicrafters] SX-111 RF Alignment

[Bill Gerhold]

The type of coil I am working with are the slug tuned with the hex hole all
the way through the material.  At your suggestion, I took a close look into
a couple of these and I do indeed see cracks in some of the slugs.

I am greatly dismayed in seeing this which means much more work than I may
be willing to undertake.  Anyone with ideas on how to break up a powdered
iron core inside a paper tube without damaging the tube?  If I am successful
in breaking them up, where does one get replacement cores?

Hi Bill;

I am not familiar with the slugs in the SX-111. There are basically 3
kinds of slugs: 1) Slugs that have a long threaded rod attached that is
notched in the end to take an alignment tool, 2) slugs that are solid
with a notch in the end to take an alignment tool, 3) slugs with a hex
hole all the way through them to take a hex alignment tool. Type1 are
held in place by a sheet metal nut around the brass screw and seldom
stick. Types 2 & 3 are usually held in place with wax or a plastic strip
that engages the threads. If the wax type, heating with a hair drier will
soften the wax and may free them. Type 3 sometimes stick because
excessive force has split the slug lengthwise and attempts to turn it
only spreads the halves and make it jam tighter. The only solution is to
carefully break up the slug and remove the pieces and install a new slug.
Good luck.
