I'm intersted in discussion on the more ancient forms in framing particularly hewing , riving(riveing) and hand splitting shakes. I have completed one frame with hewn timbers. With a need to protect the frame and no ability to do some of this hand work I opted for asphalt roof shingles. I do look forward to stripping them off and replacing them with hand splits. I have done a lot of reading but practical advice from some folks who have been there would be wonderful.
