[Elecraft] MH3 mic case

[len at ka7ftp.com]

I'm not using glue that melts that plastic together.  My strategy was rather
to embed the post into a good amount of epoxy.  There is really no force on
the mounts other than the pull of the screws.  I suspect that the plastic
"studs" were a bit short and then pulling on them with the screws started a
fracture.  Once the stress of that is done they should not stress much once
epoxied into place.  Since there is no lateral force I doubt adding fiber is
going to make much difference.

I like to mix in some short lengths of fiberglass with the epoxy. It
provides the strength while the epoxy provides the "glue" holding everything
together. An example is repairing the ashtray cover on my 1993 Mazda Miata
(with 300,000+ miles). I repaired it at least two years ago, and it is still
holding up.
