dom, that is painful, and seems quite a big bump.
firstly i would just rub off the rough edges, then see what effect it has on your work with that particularly plane. use a very fine file or even emery cloth/wet and dry.
in principle all you need to do is stop the ding catching on the wood as it goes through.
next stage probably means some kind of heat treatment as in welding some bronze in place, and then getting it machined off. the you' ll need to heat treat the body to settle it again, and at that point would guess you are getting into the cost of a new body :?
if it is a user not a looker, then you could always use one or other of the epoxy materials. the two part ones are best, and you would put them in the hole, then when nearly dry carve off, and let set properly. milliput is one name to look for. you could also think about looking for a clear epoxy which would act as a carrier for a bronze colour. then you could try to match the real thing with colour. the epoxy will basically be strong enough, since there is no stress or strain there.
otherwise i am sure we would all give it i a new home :lol: :twisted:
hope that helps too
