Hello everybody.
Once again I am looking for your technical advise.
I need to remove a scope from a Sako rifle. The problem is that the previous owner decided to mount the scope "forever" and apply some kind of epoxy glue to all the screws.
Needless to say that I can not move a single one, even with a good allen wrench and pleny of leverage.
Do the acetone attack epoxy?
Any other chemical, easy to obtain and use, that disolves the epoxy?
Thank you in advance for your replies.
Best regards,
Jose M. Fernandez

Most of the glues have a holding point of 550 degrees F. I have had good success with heating a metal rod to "cherry" red and then touching it to the screw head for 30 seconds. This seems to work best on smaller screws such as you need to remove. Do not make the rod larger than the the head of the screw you are trying to remove.

Methylene chloride desolves epoxy. It was in the paint strippers.

Mike:
Your advise sounds to me the easiest, because I alredy have an electric soft soldering pistol.
How much time do you apply the tip to the screw?
Do you try to remove the screw right after the heating or you wait until it is cold?
If you could, please give me more specific technique to do it.
Thank you!
Regards,
Jose M. Fernandez

OP mentions an allen wrench, so I would assume socket head screws. I'd try heating a sacrificial allen wrench of the correct size and applying torque to the screw until it moves.

Are you sure this is Epoxy glue and not Loc-tite? There are different levels of Loc-tite and some can be very stubborn.
I've always used Loc-tite when attaching the scope bases to rifles.

I am almost sure is some kind of epoxy glue, because you can see a transparent brillant coarse coating around the screws.
I will try with the electric soldering pistol and apply force with the allen wrench inmediatly.
I will report the result.
Thank you,

Either loctite or epoxy should respond favorably to heat.
