Jim,

I know of no way to "temporarily" release epoxies' hold on anything.
There are no chemical solvents that will soften epoxy. At least none
that you would want to use. I've been told there are some, but they
would probably destroy the wood along with softening the epoxy.

You will have to heat the bolt. A propane torch with a fine tip should
do it. Do your best to protect the wood around the bolt with a "heat
shield" and slowly heat the bolt until you can remove it. 

You don't need (or want) to get the bolt red hot. Play the flame on the
bolt for a minute or so, then let it rest for a few seconds to prevent
overheating the bolt and to allow the heat time to work its way down the
length of the bolt. Repeat the process until you can work the bolt
loose. Once you have it loose, remove it, clean out the hole and start
over with fresh epoxy. The heat will have totally destroyed the
original. You may well have damaged some of the wood as well, but you
should be able to repair that with the fresh epoxy. 

You know my motto: Measure twice, cut once. Then repair it with epoxy!
