Thanks for your answer Timbeal
I'm using pine 4 x 8 braces and they have been dried down to 18-20%, so hopefully twisting will be reduced then! I though about it, like in extrem cases the brace could pop out!
I'm holding the braces with 1" pegs, and, i'll think about it while framing, add some extra protection in those areas (thinking about larsen trusses solution for my walls). But, tell me, why do the lapped dovetail would have less surface in compression? excatly like the tenon&mortise, half of it is going to be in contact with the associate timber, the other half being in the mortise and partly on the timber surface too.
Well, my frame is over dimension for a 20' x 20' high post cape but I'm just thinking through all details!
Also, I join my tiebeam to the post by wedged half dovetailed through tenon. That might help the bent to be more stable too maybe.
I'll fit the braces after assembling the bents, then I'll be able to sbribbe fit them better, and probably get them more tight.
One more question: are two 1" pegs possible for such a small case (3 1/4" x 7" tenon approximately)?
