You don't want to use this setup to strain the spring back into place... if the clamp slips out of place, you might need to see your dentist for new teeth.

The pit in the center prevents the piston from slipping.

On the other side a 10 mm bar (I used a screw) that can freely move keeps the other side of the piston in place.
