If you want to make more than just Dovetails & Box Joints, the important thing to consider is the fence opening. Raised Panel Doors, Roundovers and Molding operations require the use of router bits larger than 1” in diameter. Jointech has designed the Ultimate Router Table Fence System... The CabinetMaker’s System™. It features SmartFence® allowing you to use router bits up to 4” in diameter. JUST ONE FENCE (Not Two or Three ) Performs Every Router and Table Saw Operation.
