Thanks to you both.I will be housing into the post 1". Was trying to figure out if there was some kind of standard/traditional frame rule on tenon size based on the timber dimension ? Also is it really nessasary to make that tenon 11" tall ? As I understand it these joints are mostly under tension,I will be double draw pegging.Just wanted to make sure I am not removing to much material and weakening the posts.I have been helping a friend felling/milling all the pine here at my property we're about to the halfway point to filling the list.It's been a great project so far. I can't wait to start cutting joints but am finding that good planing and patience seems to be key to doing a project like this ! Thanks be that I have a lot of patience and a brother with a CAD program who will certainly not be bashful in letting me know of any errors in my drawings. Great site,I have been all over it the past year or so getting all kinds of info. Gotta go cut down some trees now !!! Thanks again.
