post that is parallel to its center-line. Then rotate the posts (approximately 100 degrees for back posts and approximately 80 degrees for front posts), re-clamp them, and create a second line by drawing the ripped pencil along the lengths of the posts. Estimating 100- and 80-degree increments may sound foreboding, but it's not. Remember that the 100- degree distance is just a bit more 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, page 69). 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 mast have one left front post and one right front post. Two matching posts won't work. Same rule applies to the back posts.)
Rocker Finial (Each square equals one half inch) Rocker Finial (Each square equals one half inch) Rocker Elevation (Side View) Note: All of the cross members that are identified as seat, side, backrest, lower njngs (etc.), have reduced tenons on their ends. All of the cross members that are called spindle rungs are smoothly turned to their final diameter. There are no stepped-down tenons on their ends. 18'/V 25V winter 2009 71 |
