Miriam, thanks for the heads up about truck tubes. After checking around I think either truck or bicycle tube is the most likely source of rubber hereabouts. My hesitation about pond liner, roofing stuff, window sealing stuff etc is that none of that stuff is intended tor use around moving things like hinges...not sure it would stand up.
Guy--I have been looking at those hinges for awhile and Steve Cox' experience suggests that the new plastics have what it takes to stand up to UV, a killer for most plastics--including older rotomolded kayaks!
Anyhow, I ORDERED the hinge!
A disposition to preserve, and an ability to improve, taken together, would be my standard of a statesman...
But what is liberty without wisdom, and without virtue? It is the greatest of all possible evils; for it is folly, vice, and madness, without tuition or restraint.
