I've had a ring groove cleaner for years. I think I got at NAPA. It works great, just don't over do it, like flakes of aluminum coming out.

I have never had a problem with using the broken ring, I have a grove cleaner, the broke ring works better for me. The grove cleaner never seams to fit right on a cub piston. Break the oil ring to clean the larger oil grove. How ever if it has had replacement rings the oil ring may not work.Could be a springy think not an iron ring

Ditto. I have a ring groove cleaner. Broken piston ring works great, just wear gloves since the ring edges are sharp. The oil ring groove may be a problem, depending on if it's a single ring or one with expander and spacers.
I have an excuse. CRS.
Okay all - considering what I've heard from ya'll - I'm gonna save the expense and go with Boss's suggestion for using a busted ring. I'll let ya'll know in 35 years how it turned out....

If you choose to use a broken piston ring to clean the grooves, just make sure you choose an old ring to break!!

I use a ring groove cleaner made by Performance Tool and it works great on the Cub pistons. It came with two insert cutters to fit most grooves including the Cub pistons. Granted that the groove cleaners are designed to work with larger diameter pistons but with a little finesse they really do a good job on the smaller sizes. They're less than 20 bucks most places and I think a good investment. I've used the old broken ring method too, it's just a little more work and, like mentioned before, many oil rings are not one piece cast rings.
I see no mention of the piston material. Statistics say that it is likely to be cast iron, but aluminum is a possibility. The cleaning procedure should be appropriate for the material.
Many Cub owners are reading this and some of them do have aluminum. The electrolytes in an electrolysis setup probably will seriously damage aluminum.
