I thought why build another sled to cut box joints when I have a good sled that I simply slide the box joint jig onto and not have another sled hanging around .
This jig is based on Jim Steinbrecher’s original design on which I think I made a few refinements starting by replacing the metal pin with an oak blade .The blade is attached to a block and the part of the blade that engages into the spacers is sized to a saw cut that I made into a scrap piece that way I got a exact size as most blades will cut a slightly larger then the size measured of the blade tooth .the second item I changed are the spacers ,I used HDF laminate flooring and cut about double the amount needed and then sorted them by size using a caliper and kept only the once that where same thickness to within one thousands of an inch. other then that it is pretty much like the original design but I can simply slip this jig on my sled’s T track and tighten two wing nuts and it is ready to go . I also made a material carrier which is straight forward as you can see from the pictures .
The first joint turned out OK but a little tight which is easily corrected .
I am also thinking of another design that I may also build but we will see how this one works out .
