Monster saw works?

Have you ever had any problems with rings? A sharp edge on a ring can reek havoc in a cylinder too.

Does anyone else take the sharp edge off new rings with very fine emery?

I haven't found it necessary on modern saw rings - occasionally I'll get a piston (usually aftermarket) that needs corners and sharp edges "massaged".

My grandpa used to work up new pistons, rings, and bores on automotive engine rebuilds with Crocus cloth, mainly to eliminate stress risers and other imperfections,
especially if a block had been honed. He said that honing always left stress risers in the bores regardless of how good the person doing the honing was.
