How do you measure squish?

[Al_Smith]

You put 4 pieces of soft solder on top of the piston .Two in the center over of the rod and two dead center at a right angle .Roll the piston over to smash the solder then use a set of micrometers to measure the smashed solder .Use as thin of solder as will just be smashed not something like heavy 50/50 body solder.

You can buy it in 62 thou rosin core which mashs fairly easy .I'd probabley avoid acid core myself .Solid would work if you can find it small enough .

When I said dead center I meant towards the outside of the piston not center of the piston .All that would do is shove it up into the combustion chamber .

Thanks everyone for the advise.
