Joe, Sorry to have not replied sooner. Mom passed away Thursday night, then Saturdays storm placed hundreds of trees in all/any roads leading to home. Power has finally been restored late this afternoon. I don't see anything there that would benefit from an epoxy sealer, filler or consolidant. It needs repairs and the typical, traditional repair for hand-hewn timbers is what Mike O'. suggested, although lumberyards only have milled timbers. There's plenty of salvaged hewn timbers and hand-planed floor planks available in these parts.
