I'm not saying there was anything else used, I was just looking for clarification that you had indeed found actual evidence on your timbers of those large axes, not just that a large axe had been found in the area. Too often I hear statements, like the one we all hear about adzing, that are not founded on actual research, but on urban legend. (Not sure if that's an oxymoron, considering the subject matter.) I'd be interested to see some rubbings of timbers in your area. That will tell a lot about the hewing, like direction of travel, probable location of the hewer, size of axe, etc.
The only adzing I have seen on timbers is typically confined to reductions on floor joists, or specific shaping necessities, not for hewing the surfaces of timbers.
