I bought some bore gages on eBay and the anvils are pretty horrifically pitted. How are these anvils lapped? Can you just use a cylindrical lap? By this I mean take a cast iron round, drill it and hone it. How do you tension the anvils against the lap? Do you spin the gage or the lap? Do you even lap the anvils in situ or do you use a tool? Crucially, what is the radius of the anvils? I’m most curious how this is done professionally.
