Hi everyone,
I'm new here so let me introduce myself, I'm french living in Norway, basically engineer in industrial maintenance and interested in renewable energies, but 3 years ago I took the Pat Wolfe Log Building Course in Ontario CA and since then I'm motivated by working into that field and learn more about timber framing as well.
I have been studying books at home, practising training alone and right now I'm building my own house, timber frame based on the Steev Chappell book plan of the high post cape 24' x 24' which I downsized to 20' x 20'.
Well, I have a question today since I started cutting my Tie Beams and I didn't cut mortises inside the width of the timbers regarding the knee braces, but on the outside face, planning to fit some Lapped Dovetail knee braces. This is for the bents 1 and 3. For the middle one, bent 2, I cut mortises to fit tenon and mortise knee braces.
I read in the Tedd Benson's book (Building the Timber Frame House) that tenon&mortise braces were better without a bent and both lapped dovetail and tenon&mortise could be used between bents.
So question: is it really an issue that I'm doing lapped dovetail knee braces for my bents 1 and 3, first floor at least since it's cutted now!?
I coulnd't find so much information about the reasons for it..
I hope I can get some good inputs from you guys

I'm looking forward to hear more about it.
Have a nice day, Neil.
