I bought this jig to make a jig for cutting 4 inch dovetail joints on a large board. Mounted on my router table (with a Bosch 1617 EVS) the bit easily cuts a 24" T-slot in a 2x4. Then it was a trip to the $4 hardware store to get carriage bolts and wing nuts (make sure the bolts have a large enough square shoulder to fit the groove so the bolt doesn't turn). Voila!
