A set of the tapered ring/ piston are the ultimate, but the price ouch.
What's the best is what you have used in practice, and that experience gives you the " that is a piece of crap" eyeball knowledge when searching shopping.
I will only say that I have used this style of ring compressor on vehicle engines, small blocks, big blocks, and major overhauls on inline opposed , and radial aircraft engines. And it has worked well for many years.
Are you using a ring expander tool, the inverted pliers, to install rings?
I did mention if it doesn't slide smoothly slight resistance, but goes " clunk" or just stops, STOP pushing.
Your hammering on the piston has potentially created more damage. Have taken a loupe or magnafing glass and bright light and checked ring lands for breaks or damage? This may sound like doom and gloom, but you must be sure, positive that your parts are serviceable.
This is the ring compressor in my box at work. This is photo off the net, same style.
And ring install tool.
Well, this episode is a bummer.
One thing, if it seems suggestions are overly obvious to you, I can tell you about the Engineer that did not pull the gear pin before takeoff. Anyone can overlook the obvious.
