Braces are always confusing, the standard draw moves closer to the shoulder, the other direction is away from the butt of the brace. This pushes the brace into the square end of the mortice. See, I really put some mud on that one.

I also draw in two direction, a wedged half dove tail, I want that tenon pushed into the angled seat. If you don't you once again risk the joint being pushed in the wrong direction and fighting the wedge.

I tried draw boring a halved and bridled scarf, I now test fit them and prick, then figure. Dyslexia is no help at all in the matter. Tim
