I have boxes and boxes of NOS rings in different sizes and if you get stuck, I see some 2 1/16 X 1/8 in the pile. I make fixtures to hold rings and that way they can be turned to the proper thickness.

Mumbles, that must be quite the feat to hold a ring in a fixture while you
machine it down. If you have any photos of said fixture, I’d get a kick
out of it.
I watched a young English fellow, Mr. Crispin made some rings for his
model engines on YouTube, starting with cast iron pipe. Looked like
a challenge!

You may think I’m nuts for suggesting this idea……….. would it be worth heating the piston and then dunking it in ice water to hopefully break the ring away.

You’re not nuts for suggesting to heat the piston up, as I’ve already boiled
it in a pan of water twice, and danced a bottle torch around the stuck ring
another two or three times, besides continuous soakings in witches brews.

However, a mental examination may be required to convince me to throw
it in ice water after it’s heated……. just seems cruel !

Yea Bucc sounds like a stubborn ring. After boiling that piston in water I would
sure think it would have come off or at least free up. Have you got some kind of a fixture, like take a board and cut a 2inch circle, or size of piston, cut circle in half so you could lay piston inside half circle, being held in position, so piston don’t move, get a small punch, find ends of ring and carefully tap it till it frees up.
I just wonder what that inner edge of piston where ring sets in will be damaged from being froze for so long.

Necks, I have done what you’ve said a few times already. I clamped the connecting rod in
the soft jaws of my vise, and took a tiny punch, gently taping on the stuck end of the ring.
With only one inch of the circumference of the ring left stuck yesterday, I thought
sure I’d get it free today, but after another 1/2 hr messing with it, I wasn’t any further ahead!
There’s always tomorrow! The engine never was froze up, and cylinder was decent
for being over 80 years old. From what I’m seeing, I think it’s mostly ancient carbon
that has the ring stuck.
Oh well, at least I got the new hubs and tires on the boat trailer today.

I generally had good luck with the boiling water trick, is their a way you could keep the ring warm, like a heat gun pointed at that ring while you tap on it. ( may need the boss to hold the heat gun, while you tap). Try a little harder tap on both ends of ring, gotta go, has to come off.
Don’t give up!!!

I’d really like one, but I just have to convince myself to spend even more
money. I have a milling machine on order, and of course that will require
tooling. Maybe I could tell the wife Uncle Joe bought me the ultrasonic cleaner?

Uncle Joe giveth and taketh away!!!!!
