Hi Folks,

I'm in the midst of CLAing an Argus C3. The viewfinder lens on the inside of the camera was apparantly held in with a dot of some kind of glue on the edge of the lens, which let go a long time ago. What's the acceptable replacement glue for this? I'd assume it should be something easy to dissolve and break for the next guy 50 years from now to clean both sides of the lens...

Usually a dot of Duco household glue or that cheap stuff Dollar Stores pass off as contact cement.

Thanks for the suggestion! I did some googling, and while there seems to be very little out there about gluing glass viewfinders and lenses to metal and bakelite, someone mentioned the use of burnt shellac. I happen to have some orange shellac flakes lying around-- all you do is put some in a can, light it on fire, let it burn for 5 or so min., and then you have a somewhat weak glue that's great for bonding non-porous materials. It's also easy to reverse with denatured alcohol...sounds like the perfect stuff for the job. The remnants of glue on the camera are kind of brittle and orange, so who knows?

A "glue" used by many Japanese firms (although, yes, the C3 is not Japanese) was a dab of nail polish. This was done even more so in transistor radios than cameras.

I use Future for floors and if you need to take back out anything with ammonia, windex, will dissolve the future. Been using it for years and have never had one come unglued. Also works great on plastic, it will no fog as some super glues do.
