Andy/David,
Thanks for the thoughts. I was thinking about this further last night and decided, given the geometry of the piston and the head, that the only place where I would get corroboration between the two reading was at the point where the solder touches the cylinger wall. This would only occur in the first fraction of a mm at the wall. When I measured the solder, I didn't notice this, as the solder was slightly crimped from cutting.

I thought hard about the potential gain in compression with the 0.25 but
I am going to put it back together with the 0.5mm shims and call it a day.
Thank you both for your help.
Rick
