Can my displacer be a thin piece of metal , or does it need to be thick like all the other ones I have seen?

Thanks

On a tin can engine........a thin piece of metal does not "displace" a lot of air. The job of the displacer is not that of a piston like in an engine, but to displace air from one side to the other. It needs volume to do that.

Maybe I should think about changing the name of the "displacer piston" to just "displacer"?? and leave the name "power piston" as is??
