Chris,
Good to see an update on your superb build!!! As usual, you are several steps ahead of my Salamandre and I will continue to glean tips and techniques from your great log. Your accuracy, clean cuts and planking are an inspiration to us all.
The treenails on the planking are executed perfectly!!! What size wire and material did you decide on?
Good call foregoing the notches...wouldn't it be nice if it were full size and you could swing a hammer and chisel them with no worries!!
Do you plan on putting bolts on the keelson? I'm close to laying the keelson and have been working on bolts. I plan on 2/frame and will leave them slightly proud of the surface vice flush, like treenails.
Thanks for sharing your awesome build in such detail and with great photos.
