hey everyone, as far as the drawboring, I have always prefit, mark the tenon and drawbore, assemble. I have seen the tilt method that derek speaks of but i personally like offsetting and then drilling perpendicular to tenon. If you want to make an accurate mark. Take a peg the same diameter as peg hole find the center of the cylinder on the endgrain then offset a driven nail. Grind the nail head off and make the shank a sharp point. To the point on the circumference where the nail is offset draw a line along the length of the peg. When you put the peg in you can use your line to direct precisely. Tap lightly and you have a good mark. I like watching the 1/16 draw tight.
If you have intersecting timbers that are not perpendicular do you all drawbore towards the nose or square to the shoulder?
