Re: Epoxy ?

One point not covered by anyone else (that I’ve read): your original post said once epoxied, never to be apart again.

Well, you have to be extremely patient . . . but my friend Ted Shasta observed that epoxy finishes on furniture carry a warning not to allow alcoholic drinks to sit on the surface for an extended time.

I had a brass model with some weights epoxied inside. Later on, I was kicking myself for doing that so permanently, and remembered what Ted had said. So I put the model in a jar and filled it with 91% alcohol and . . . literally . . . forgot about it. Months later, I came across the jar and was quite pleased indeed to find that the weights were now separated from the model and could be removed. Elapsed time to success: Unknown.

Obviously, limits are involved: objects impervious to alcohol are required. Laminated joints are much less likely to give up. And this isn’t going to work for something you glued together last week and want apart NOW.

But if you don’t mind waiting until IT decides to work, it IS possible.

Thanks for the replies - they confirm that what I've been doing all along
is a good idea to just keep doing it ... which has been to wait until the
epoxy is fully cured. Typically I set 30 minute epoxy aside for 12 to 24
hours - I mix it on a small piece of hard surface cardboard ... and use
the left over on that piece to test if the cure is complete. The extra
time has always proven to help.
Yes, I did go to Wikipedia and other websites ... before I ever asked
the question ... they were all too sparse on the "practical side" of
epoxy - lots of stuff about how it works and such (without anything
I'd call the "details").

Soooo - no short cuts for epoxy. Sigh. I love the way it provides a
strong bond and is non-conductive. But I'm always careful to only
use it where I won't have to take it apart (ever).
