Folks,

I have a Zeiss riflescope which had a claw mount ring clamped and glued to the scope objective I have since removed the ring but the glue/epoxy remains. Any idea how to remove the cured glue without damaging the scope objective?

Thanks for your help
Joe

Avoid the temptation to use heat. Wink

Seriously, there are epoxy solvents out there; perform an internet search on 'epoxy solvent'.

Joe, try sticking it in the freezer for a couple of hours and then try to "chip" it off with a mylon or plastic scraper, spatula.

George, just curious--what is the technical reason not to use heat? Are the chemical charges in scopes susceptible to causing problems?

I've always figured it would be a bad idea to get to close to a heat source with your scope, but didn't really know why.....

Problem with heat is you might make it too hot...

1) exceed the allowable expansion amount of the tube verses the glass and its seal.
2) burn the seal, glue or baked on coating..

Never know how things might react. If the temp drops I can take it outside and see if that makes a difference. Tried that last night but it only went to -10 or so Not cold enough...

Makes sense, I considered much of that...

I'm such an idiot, I'd probably take an acetone or MEK soaked rag and just hold it on the Epoxy and keep on doing that...., or actually not so crazy, Golfworks sells an epoxy remover, and I would actually try that...

Good Luck

Ditto
Should pop right off after freezing.

Fish,

The glass and the tube will expand/contract at different rates and you might wreck the seals or crack the lenses. Also, I doubt high heat would be good for the lens coatings. Wink

Methyl chloride takes the epoxy right off.

However, do a small area on the inferior surface of the scope first. You want to see if the methyl chloride effects the finish on the scope itself.

If it does, then I agree with using the freezer technique (i.e. freeze the scope and then scrape the epoxy off with your fingernail or something plastic).
