Once the mortise reference lines are drawn on the posts, you can easily transfer rung-mortise locations directly from the story sticks.

than 90 degrees and the 80 a bit less. All you really need at this point is an estimation so you have something on which to mark mortise locations along the lengths of the posts. The exact angular positions will be created later using two types of rung-mortise jigs.

After you've drawn reference lines along all the posts using whichever method for establishing these lines, lay a story stick along one line on one post. Mark the mortise locations along the length of the post by transferring the information from the stick to the post (see photo, above). Be very accurate with these placements along the lengths. Then rotate the post to the other line, flip the story stick over, and transfer the other set of mortise locations. (Editor's Note: You must have one left front post and one right front post. Two matching posts won't work. Same rule applies to the back posts.)
