Hello everyone! Exactly what it says on the cover, this video is me pitting my self designed tablesaw box joint jig named #WoodfathersJig against the very high quality and pricey router table jig, the Incra LS Positioner. I had a great time putting this one together, hopefully it helps show what you can do.
Just an fyi, the only rule I set myself was that I was only allowed to make one joint on each jig, and then straight from jig to glue up. Both joints can be cleaned up with handtools and finessed before glueup, in which case both jigs would be able to produce perfect joints. For this video I didn't do any cleanup at all, straight from jig to glue, to see what you get out of the box.
