How do you glue the linkage back on a glass diaphragm on an early Automatic reproducer? It just accord to me that this should be in the Tips section.

I believe Steve Medved has found that Loctite GO2 Glue works the best. I just had a conversation with him on this topic at the Orlando Phonograph Show.

One micro-small drip of Gorilla Glue GEL glue. OR if you wanna do a FACTORY job.......put a flake of shellac on the foot and warm it over a candle until the flake melts, then stick it in place on the glass!

Again Stratina, was the original method, to attach the glass and cross head. (See Manual of the phonograph, section on reproducers and recorders)The surface must be extremely clean with Benzine,acetone to stick, and give it a full day to dry, it can be dissolved with hot water to change the diaphragms. Chuck and I have discussed this several times.

I can kind of see why someone might want to use
the Loctite GO2 glue for attaching the eyelet to a
glass diaphragm.

Especially when patience runs thin.

The secrets to using Peter Wall's stratena glue are:

#1) The parts much be absolutely clean and dry.
Peter says to use only acetone to clean the parts.
I've successfully used denatured alcohol to clean
a mica diaphragm and the bottom of a copper cutter
holder before gluing up an Edison recorder.

#2) Wait at least one entire 24 hour day after gluing,
before even thinking about touching the glued assembly.

I have had much success gluing both copper and aluminum
to mica, using Peter's stratena glue.

So far I have never yet tried gluing down an eyelet to
glass, using Peter's stratena. I have no first-hand
experience with this combination. All I have are
Peter's detailed instructions which tell how to do
it and he says it works.

Others have reported that it's fairly easy to pry and
twist off an eyelet from glass which has been glued
down using stratena. One possible reason for this
could be that the parts were not clean enough
when glued down.

No doubt that the Loctite GO2 glue works and sticks
like mad. But then what of getting it loose again
later for adjustment? Maybe that is not so important
with glass and an eyelet because once that is together
it should never have to come apart again unless the
glass breaks.

Then if the glass breaks somehow the eyelet can
probably be cleaned off even if the GO2 glue has
to be flaked off using an exacto knife or a razor
blade.

But, for me, when I get around to trying a glass
diaphragm, I'll try the stratena first. Then, if that
comes off, I'll move on over to the Loctite GO2 glue.

I can say for certain though that Peter's stratena
holds like the dickens for mica to copper or mica
to aluminum!
