Okay, I'm in the process of rebarreling a pair of Pedersoli rolling blocks which are to have 11 degree target crowns. The 11 degree part isn't a problem but I am unsure about the treatment of the edge of the bore and crown. Do I leave the edge "sharp" so to speak or do I break the edge with a crowning ball like a normal crown? The sharp edge looks easily damaged but the use of the crowning ball would seem to be counter-productive. Any input here would be much appreciated.
