Hi everyone tonight

I was just reviewing the posts above and noticed that ken had shown an interest in the 40 foot trusses in the Williamsburg Church and their construction, well just to catch up,--

The trusses are constructed similar to a bridge truss and are really strong,in fact the last truss from the south stone wall supports not only the ceiling's 40 foot span, but a good share of the weight of the spire which is supported equally on the stone wall and the first truss.

There are running length wise over the upper surfaces of the trusses hewn timbers that serve as purlins in other timberframes, they in turn support the rafters that seem to rise independent of the trusses but in reality are taking the roof's weight, including the present heavy snow loads

Hope you enjoy
