just talked to Frank Bowman and confermed that he is out of the Ring business. so i made some fixtures to make some S/T 60 rings for myself .i ran about 32 oz of fuel through the newly re-ringed engine yesterday and it has good compression .the ring is not heat treated . i have about 6 blanks left if there is any intrest ,i could fit a ring to a piston and sleeve
