That's great that these are scribed CG barns and that you've been seeking some examples. Yes, we can visit them. It would be great to meet. I now know of 5 of these CG barns... only 1 is built of sawn timber. 4 are in one town, 1 in another. According to Google Maps, Barnstead is about 80 miles away from these barns, which are in Gray, Maine... they give a travel time of about 2 hrs.
Tell me, how did you know they are scribed? Was it the marriage marks? I must admit that I'm foggy on what exactly "scribed" means and how to know it on sight. It sounds like it's an older method. In order to get everything in a common plane, it involves custom fitting/scribing of inexact (hewn) timbers. (correct?)
This CG style seems like an easier and simpler method, especially in regards to raising. Perhaps that's why it was done? Upon erection, the major roof frame is already in place, and its easier to erect a frame transversely, etc... but I'm only speculating.
Another detail I wanted to mention: The rafters and crossties are cantilevered over the posts a bit in this CG style. If you look at the pictures again you can see that Barn 2 exhibits this to a greater degree than in Barn 1.
Anyway, given the travel distance between us, it will be a full day for sure... I will try and pin down construction dates more for these buildings, so lets plan on 2-3 weeks out. I've been going by owner accounts and my own observation/knowledge for dating. I'll meet with the historical societies and owners again and see what I can get for more definitive numbers. From what the owners say, Barn 2 seems like the older of the two. But we may not be able to trace it exactly... it's like trying to document what you had for dinner 4 and 5 tuesdays ago!
