I am friends with many engine builders but I've never seen anyone install circlips into pistons the way that I've come up with. I believe that it's by far the easiest way to install them without worrying about them going flying across the shop and without cussing your way through it.
I also share my process of assembling the piston and rod assemblies.
I have different ways of installing the circlips, depending on which end I'm installing it so be sure and watch both.
