Here are a couple of updated sketches of the framing from my notes:
as originally framed in 1788 as best could be determined 1837 plan. The basic layout of the trusses and rafters didn't change. If I knew a little more about framing my notes and the drawings would benefit. Every time I have visited this structure I have been impressed by the artistry of the original builders. The hewing work seems exceptionally fine to me - and of course the timbers they had to work with are quite impressive in themselves.
