Replying to Binding Removal?

I'm trying to remove the bindings (Rossignol Axial 2's) off of my brother's K2 Extreme skis that he said he doesn't need anymore for my new 4FRNT CRJ's. I was able to get a few screws out with a drill, but, with all the other screws I've come to the problem of them being epoxied really strongly. When I attempt to unscrew them with a drill, they don't move in the slightest and the drillbit just spins. Is there any way I would be able to easily remove them without getting to a shop? I need to lessen the amount of epoxy and I was told that using a hair dryer might work, because it would heat up the epoxy and make it easier to remove the bindings. Is this valid? How would I be able to get the bindings off?
