[Hammarlund] SP-600 Knob and tag removal help!

[Cecil Acuff]

Greetings,

        Anyone have any experience at removing a set screw that has had =
it's internal hex shoulders stripped.  It is frozen and finally =
stripped.  I had tried penetrating oils before applying too much =
pressure, but to no avail.  I am trying to save the knob...it is one of =
the main tuning knobs. =20

The only thoughts I have come up with is to enlarge the hole through the =
plastic part of the knob between the part you grip and the skirt and use =
an easy-out that fits snugly into the opening of the set screw.  If =
successful the only tell tale would be the cleanly enlarged hole in the =
plastic....I guess drilling would be another option....I hate that one =
though for obvious reasons.=20

Anyone have any better ideas that you may have used....

I need to get the knob off to refinish the panel and all the others are =
free!

Also....has anyone tried to remove the rather thick aluminum tag that is =
glued to the front center of the panel on the VLF version.  If you have =
not seen one it is about 2" X 2.5" and probably 1/8 th inch thick...it =
looks like it was applied much like the metal property tags that many =
companies put on their equipment. =20

I can't imagine trying to strip the front panel with aircraft stripper =
without damaging the paint on the tag.  Any prying would only destroy =
the tag for sure.  I thought about maybe heating the panel from the rear =
ever so carefully in hopes of softening the glue that holds it in place. =
 Reattaching it should not be a problem if I can just get the thing off =
to allow me to refinished the panel.

Any suggestions would be appreciated....especially how not to do either =
of these tasks would probably save me some grief!

Thanks...
