: Also, if you are tying the deck-beams in place, as per Mark Starr's method,
: you will have to have enough room to drill for your twine and still miss
: the rib mortices. I had a couple of Deck-beam mortices that barely missed
: the Rib mortices and then had to extend the twine a ways past them also.
: That's not a serious problem if you are tying and pulling the twine
: together for added tension.

Why didn't you just lash the deck beams on the other side (i.e., fore vs. aft of the beam)? It really doesn't make any structural difference.
