From memory, the timber has to be “wet” to utilise it’s natural elastisity.

I guess the most appropriate tool for shaving the inside radius would be a spoke shave or drawknife…...........or if you are lucky enough to have one, a compass plane.

The guy was building chairs so I expect he was happy with the smoothness of the grain, although I can’t remember what the timber species it was he was working.
