When reusing barn beams in a new structure, what should I do about old mortices? I was thinking about making snug fitting wood plugs to glue in place as the original tennon would have, then cross drill it and drive peg through, and finsh the plug and peg flush to the beam. I do understand that old mortices should be oriented in areas of the beam that will see lower stress where possible. Do people do this when reusing barn beams or do they do something else?
