Well that's a fine looking machine KG! Mike here. Sorry for the delay but as I just explained to KG in an email, I've been recently afflicted with a case of Flesh Eating Ebola virus and that is as explained to my wife and nurse daughter and , of course, self diagnosed. I may live but not much longer in view of the fact that I have now managed to pass the disease on to my wife.
Don't know for certain KG about hardness of the bearing race. I would expect something about Rockwell 50 based on what I know about other bearing races. I also don't think that it makes much difference in this application because we got very similar results when using aluminum rollers. We decided to use steel only because we have a bunch of these bearings on-hand and, they seem to work. I think that you will see that the knife edge does not leave even the beginnings of a mark on the bearing surface.
I like where you're starting a bunch KG. Should be very interesting!
