Chair Making Joinery Started

Parts are mostly milled for the Kingston Library chairs and we've started cutting and fitting joinery. We've been trying to get the most out of the power tools to reduce the amount of handwork necessary later on and to create relatively simple setups on the tools that will give us repeatable and precise results.

While Matt was mortising the posts, I cut and fit the back seat rails to build our H's. I made a wedge milled to the cant angle of the back posts for the sliding table saw cross cut fence. I screwed the wedge to the cross cut fence and then we cut one end of all the crest rails, back splat rails, back seat rails and the back stretchers to the cant angle. We then cut the back seat rails to length off the drawing using the same wedge on the fence. I then ripped the cheeks on all the back seat rails with the table saw. After fitting the cheeks, I cut the shoulders using the sliding table saw with the wedge on the cross cut fence and an L-fence attached to the rip fence of the saw to leave a space for the cut off piece to go without getting trapped.

Here is a photo of the table saw setup for cutting the tenon shoulders.
