Dang it you guys really know how to confuse a guy. Are these cams hardened on the surface, like maybe I'm past the hard outer shell? This photo depicts a quick pass on a pretty coarse wire wheel on a bench grinder. I have 2 sets of adj lifters, one from a swap-meet, the other from an 8ba I tore down. They look old and hollow and 'johnson-like'. I did my 5 lb-lbs flour sack test (60 inch lbs) and about half need a squeeze in the vice. A sharp file on the bottom says they are very hard on that surface...My jailbars have fat fenders and going back 'in' if original parts fail is miserable. My McGuyver side says run the pits, but my 67 year old aching back and shoulder side says use some covid check to do this part right. My current project has enough McGuyver to make the TV version break out in a cold sweat.
