LASER Galvo mirror adhesive

[Joe]

Mirrors keep falling off my "Cosmic Storm" Lightshow LASER. Not only the
galvanometer X Y scanners beam mirrors but the proximity switch mirrors
inside the galvos themselves.
I'm thinking of using high impact crazy glue or old NOS radio TV cement 9
(the red stuff)

DO NOT use Crazy glue.

I'd suggest 2 part Epoxy. 5 minute Epoxy is probably adequate and can
be removed more easily than the long cure type, though that's stronger.

Two surface-coat 'impact' adhesive might also be a good bet, as this has
very instant 'grab' characteristics when both surfaces are dry and then
brought together, but has the added advantage of retaining a degree of
flexibility in the bond, which may be helpful where a mass is being thrown
about with 'instantaneous' stops. Based on the same thinking, a superior
quality silicone rubber compound might also work well.

agreed,the silicone in a layer thin enough to capture surface deficencies
but not thick enough to allow for flexibility would be optimal.

it bonds to glass easily and is waterproof. and easily cleaned up before it
gels.

th only dr wback is 24 hour cure time to full strength where the mirror
must be held motionless or it will creep

I'm impressed with polyester glue for lots of general purpose use where
the very highest strength isn't needed. It seems to bond to a larger
variety of materials than many. The downside is it takes an hour or so to
set enough to hold and 24 to get to full strength.
Dunno about brands everywhere but one in the UK is Evostick Serious Glue.

Thanks Sam, I tried all including windshield mirror repair kit.
Best fix is yes the smallest dab of 5 minute GC epoxy then re-adjust the
Galvo brackets.
And thanks to all who replied...the LASER is holding in action with the band
