PZL compass repair - Tom ?

The problem with regular epoxy is that when cured it is relatively hard and
brittle. Thermal expansion and contraction of the epoxy may not be the same
as the plastic being glued.

Loctite "Depend 330" when cured remains flexible and bonds well to a variety
of materials. It will, for instance, bond metal directly to fiberglass with
no lay-up of FRP over the metal required. Useful stuff to have around, but
it does have a limited shelf life, so the large "economy" size ain't.

Hi Tom - Two more questions:

Yours was definitely leaking out the threads
in the back ?

Yes. I'd put it on the dash of the car on a paper towel and let the
winter sun heat it up, then look for damp spots. Tried to figure out
some kind of tool to open it up and look for O ring to replace, etc,
but all attempts at opening failed, as I didn't want to break it.

Loctite 330 costs more than our gliders.
From the Loctite product data it looks like
good-ole Loctite 243 is more appropriate
in any case - What am I missing here ?

Probably any decent epoxy stuff will do the trick. Bumper's into
exotic tools & such...

I roughed up the gap with a Moto-Tool first.

Not familiar with Loctite 330. How does it compare with Aviation Permatex
for this use?
