Cylinder Walls

Thanks Moper.... I was about to say that chrome-moly is a new term for rings for me! Moly rings are iron rings with some degree of moly facing on them; a lot that I see now seem to be a thin moly facing on an iron ring. I have seen some in the past that appeared to have a slot in the iron ring surface filled with a light colored moly material. But either way, they are basically an iron ring with a special top ring treatment.

Chrome rings facings are quite different as said, and take care to seat. Not attractive for a re-ring job. I use moly rings on everything for the ease of seating, and would not hesitate to use them on a re-ring.

BTW, the Hastings recommended surface finishes for iron vs moly are not all that different.
I need some more punctuation marks ........How ,,,,,,,,,,about///////////this::::::LOL;;;;;;;;;
