If it is indeed stuck, I think I would try lightly tapping on it with an impact driver. You don't have to use a BFH.
Yes Dingy, I have a BS in chem eng. All of my work experience has been working in a mechanical engineering job at nuclear power plants, usually as a Mech Design Engineer, sometimes as a Project Manager, or Project Engineer. My first job was startup and test engineer checking out and getting the systems to work and running properational tests on the equipment at the Brunswick Nuclear Power Plant. Prior to getting my degree, I spent a tour in the US Army where I went to school for 40 weeks to learn how to repair the target tracking, target ranging, and missile tracking radars for the Nike Hercules Missile System. I also repaired the analog computer that received information from all 3 radars and guided the missile to its target. Got to spend about 16 months in South Korea on a missile site way out in the middle of the rice paddies. The Army experience has served me well in my career.
