This thread is getting interesting as I am just rebuilding a new engine for my
Spitfire and I'm just trying to mate together con rods with floating pins and
pistons without circlip groove. I have heard from some local engine builders
that
they've used aluminum buttons in the pin ends but I'm a bit suspicious when
thinking them scratcing against cylinder walls... but on the other hand pistons
are of the same material as well... Any experiences, anyone?
