Curious about wooden canoes
My 1908 Morris was missing the center thwart, so I built a new one. It does not have the nuts that go on the bolts. The bolts on this Morris are made out of threaded rod bent over at the top at about 1/2 ". Some of the bolts have square iron nuts, bur no washers. The threads on my Old Town are 12NC 24 which is too large for the Morris bolts and the next modern size smaller 10NC24 is too small for the Morris bolts. No stores around seem to carry a middle size, which would seem to be 9NC24. I tried to re thread one of the Morris bolts with 10NC24 but it just messed up the area on the end, so I stopped. So, the question is, what size threads were used on the Morris seat and thwart bolts, and are nuts that fit available. I suspect square iron ones are not available. I have used a couple of Old Town diamond bolts after cutting the top part of the bolt off, bending the top, and using 12NC24 nuts, and if nuts are no longer available I will do that again, but I am just interested in any input on this issue.
