Ken, how do I go about doing a full survey? I have read something about it on the Guild homepage, but I don't remember much about it. I am sure there is more to it than just taking a few measurements. The next time I go over there, I'd like to have a list of things to look for/photograph/measure. This barn needs some help.
Here is a picture of the outside, not much eave overhang.
Here is a broader shot of the roof framing. The beam on top of the tie beams supporting the rafters was added by the current owner.
I don't know if all of the joinery was bored with a screw type bit or not, I will have to do some more investigating. If that type of bit is c.1800, does that correspond with what we are seeing in the frame?
