R9PLUS BENCH OPERATION CHAPTER 1 Making the Beam The heart of the R9 PLUS Dovetail Jig is the beam. A typical beam, shown below, is 30"[762mm] long. A 30"[762mm] beam can accommodate board widths of up to 18"[457mm]. Beams can be made shorter (minimum 20"[508mm]) or longer, in 10"[254mm] increments. Because of the template’s unique “step over” ability, beams can be made longer to suit any width project. The beam is equally suited to router table or bench operation.
