I have an electric chair that someone cut the power cord and power pack from and are no longer accessible. I'm removing the motor and one of the bolts in the frame to it spins relentlessly along with a locking nut that is supposed to be permanently fused to the frame (I know this because the other locking nuts are attached to the frame) but this one is not. There is no room to put another wrench to the nut while loosening the bolt. What is the best way to remove this particular bolt? Not ready to give up on it but definitely need some suggestions.
