I was removing good rod cores from a bunch of old pistons today and ran across this ring. Early gapless ring?
It looks like somebody needed wide rings and couldn't find one, and used 8 thin ones to fill the gap.
Not unusual, guys do it all the time with old gas engines, and old tractors.
Cord Duaflex rings, very popular in europe in all ranges of engines since the mid 1930's.
I did something similar. I had a 1910 engine I wanted to keep original, including saving the old flat top pistons. There was too much ring slop in the top ring so I machined out the bottom of the groove. I also had the replacement rings ground thinner on a magnetic grinder so that I could add a spacer under the ring, the kind you see for oil rings. Worked fine. After break in, there was no blow by.
Richard, that was neat! Never thought of using a surface grinder with a magnetic base to do that!!!!!
thanks for that bit of info.
