Neat, I've never seen it done that way before. Always just with a flat plate over the chamber with an inlet hole and a breather hole. Where do you put the scriber point? At the edge or the middle of the chamber? I did consider the space between the piston and cylinder down to the first ring gap but figured that it was likely far smaller than the errors in my other measurements so I ignored it!
