JJPRemoving Epoxy from Objective on Zeiss - ring mount ???
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

enfieldsparesYes, try and "float" it off. In other words either water, WD40, "ballistol" or rangoon oil. All fluids that will "creep" between the epoxy (you hope) and the glass lens.
Or...contact the help number on a packet/website of makers of these glues and ask for advice.

RIPYou do mean the objective bell, not the glass lens, surely, unless Walter mounted that scope in the claw rings.
Try putting it in the freezer overnight. If the scope bell is of different alloy than the ring, differential contraction may loosen the joint.
Of course the Zeiss people could get the glass out of the scope and put a torch to the epoxied ring, and then refinish the scope tube.
Do not allow Walter to undertake such a job.
If you are willing to risk the scope to your own hands, wrap it in wet rags with the ring exposed and submerge the rest of the scope in icewater, and apply a propane torch to the ring half briefly, until it loosens ... assuming the penetrant solvents did not work. Hopefully some Kroil will loosen it.

HB01I have never had any luck dissolving epoxy with acetone, even under ultrasonication (industrial applications).
You could use a soldering iron to heat the ring half or the epoxy.

500NEHi JJP,
Not an expert on this, but my gunsmith once educated me that the glues normally used for this kind of work will go soft if heated. I do remember that the temperature should be around 160 Degrees Celsius (whatever that is in Fahrenheit), the scopes are designed to withstand thos temperatures.

new_guyI've used the commercial paint strippers to remove epoxy from anodized aluminum scope tubes.
