How to Remove Piston from Cylinder

Is anyone in the chapter a surgeon or does anyone know one personally? I
have a surgeon friend who's an expert in performing abdominal surgery
through a tiny incision. He could remove your appendix though your belly
button. I think someone like him would find it possible to work through the
spark plug holes and squeeze the ring enough to let it slip past the top of
the sleeve.

A member of our EAA chapter has a cylinder from a Franklin 150 engine (off
the engine.) The piston was pushed too far up and the top ring sprung out
so it now overlaps the cylinder sleeve which locks the piston in place.

Does anyone have a technique to get the piston out? Preferably while doing
the least amount of damage. (So no explosives, please!)

Thanks,
Paul
