I have been known to smack the core to break it into pieces as it will
fracture fairly easy. Then flip it over and the pieces fall out. Or how
about a little bit of epoxy on the end of a tooth pick. Let it dry and then
unscrew it. Of course, you need to make sure you don't glue the slug onto
the form. Can you drill a home through the board to allow it to pass out
the bottom? You might be able to shine a bright light through from the
bottom of the board to see if you would disturb any traces. Just some
ideas..

I don't know if this rig qualifies as a boatanchor, but I thought I would
ask as there are many here who are knowledgable.
I got the rig from a freind.
The 40 meter rf pot has a problem. The ferret core is bottomed out and
won't
screw back (upward) or catch the threads/coil.
Is there a tip or trick to 'grab' the ferret core to get it to catch.?
I'd hate to have to tear the board out or send it out for service.
Any suggestions appreciated. Josh
