Cracked coil Form Slugs Help!!!

[Steve]

Mike and All

I have the coil form out now and it is easier to work on.  I have the feel
that there are other cracked cores in this unit.  I had one input that said
to use some white glue and glue a small dowel or sliver of wood in the hex
hole and then it should back out.  Once out then glue with super glue.  We
will know in the morning when it is dry but I am not giving it much hope.  I
may need some spare cores to get the cores out of them if they can be found
anywhere.  This is a FLDX400 so perhaps a dead FT-101 or FTDX400 series
might have coils with the right cores in them.  These cores are white
plastic tubing and have a square black area on the bottom where the leads
are attached to, on the other end where they attach to the chassis they are
the snap in variety.

Hi Steve,

Well they are broken so may as well try gluing them back together. Get 
the core pieces out with heat and clean the wax off the surface where 
the glue goes and try your favorite glue. Super Glue will for sure put 
the pieces back together. Will it work once done? Maybe, but you have 
nothing to loose now. You can look up ferrite on some website or use 
Mini Ring Core Calculator software to show you what freq ranges the 
ferrite materials are recommended for. My guess would be type 43 ferrite 
as that works on HF well.
