I have heard about unpegged bracing but I did not know it was widespread. I cannot recall seeing an unpegged brace in northern New England. I have seen a barn where the braces were not flush with the outside face but held in around one inch. Sheathing boards are often nailed to the braces. Brace tenons are often 3 1/2" long to 4", always barefaced. Long braces are extremely rare in my experience. Peg materials I have seen are usually red oak but I just surveyed a barn with hexagonal pitch pine pegs and an ell with octagonal red maple pegs, both here in Maine.

Does anyone know how the framers of yesteryear decided to size there braces? Why 36" vs 42" vs 48" etc.
