I am currently building a set of 6 Arts & Crafts chairs as designed by Kevin Rodel in FWW. I will be doing a project posting soon, but wanted to recommend a tool that really helped me on this job.
In order to reduce individual fitting and trimming of all the joints, it is necessary to make mortises in the same place on each piece. With this jig, it’s easy to do. The tall back leg has 5 mortises, half of them angled. I was able to set up the jig, and place the mortises so the tenon pieces mated up correctly.
Set up is easy, establish the location of the mortise with the accurate Incra scales on the jig, and raise the bit to make the cut. The only slow down was when the piece to be cut got in the way of the crank on the router lift, I switched to a t-handle hex wrench which was a bit slower to use.
Other users have complained that they cannot make mortises deep enough. I solved the problem by using 1/2 shank bits, they are longer, and I had no problem making inch deep holes.
Checking with a dial caliper, I realized I was getting machinist accuracy in woodworking, within a few thousandths. I can see these being beneficial for loose tenon, as well as traditional mortise and tenon joinery. This project has both, and it worked fine.
