crazy pioneers with thier axes, eh?

i can tell you that in my part of the world (central ontario, canada) timberframe barns are the most common frames, most around here built from 1850-1910 plenty of broadaxe work and also lots of sawn timber
the barn on our farm is half sawn and half hewn
the sawn wood is elm and the hewn wood is ash and pine, all the rafters are round balsam fir
those elm beams must have been a bitch to join....
please give us an update on your booklet as it would serve me also
