    I have some Bob Smith epoxy that never cured on some centering rings and a motor mount. What would be the best solvent to remove it so I can start over? It is still sticky and actually flows quite slowly. It didn't get hard enough to really scrape away.

    Denatured alcohol, acetone or lacquer thinner all work pretty well. Acetone is probable the most heavy duty of the three.

    A quick soak in denatured alcohol worked perfect to get the parts apart and everything cleaned up. Thanks!

    I had a motor mount and the epoxy was still tacky after two-three days... I put it in the oven for about 10-15 minutes that was pre-heated to 250 F (The Mrs. was NOT home!!!) I took it out and let it cool off... after a few hours the tacky was gone. The heat helped the curing along (which I suspect was due to not enough hardener in the mix). One word of caution: Take it out and do not mess with it since the glue that holds the tube windings together also softens. I caused a bit of a wrinkle in the outer layer because I disturbed it while it was still hot.
