After inserting the C-clip in the right side of the pistons and measuring the ring end gap, it was time to start the assembly process.
The assembly process consisted of cleaning the cylinder, cleaning the piston, cleaning the rings, installing the rings on the piston, applying clean oil to the cylinder bore / piston & rings / ring compressor tool, tightening the ring compressor tool around the piston & rings, pressing the piston down in the ring compressor tool so the piston skirt protruded beneath the tool, setting the piston / compressor tool onto the top of the cylinder with piston skirt inserted into the cylinder bore, then using the handle of a ball peen hammer to drive the piston & rings down into the cylinder bore.
Once the piston was inserted into the cylinder, I pressed the piston down the cylinder bore until the piston skirt was protruding from the bottom of the cylinder an amount sufficient to allow me to insert the wrist pin into the piston. Then I placed the piston and cylinder assembly into the storage container then repeated the process for the next piston and cylinder.
This band type ring compressor tool was a bad Amazon buy. The band would flex open as the ring was reaching the top of the cylinder and the ring would pop out. Fortunately I didn't push a bad position and break or crack any rings. This ring compressor tool went to the recycle bin - I went to the local auto parts store and purchased a wind up style ring compressor that worked well and saved the day:
