Materials
Board, 2X6 (actual one and one-half inches thick by five and one-half inches wide) by 32 inches long. The jig could be made on a smaller board, even a 2X4, but the larger board provides room for clamping it to a benchtop.
Wood, plywood or plastic for cleats, about one half inch thick by about one half inch wide, eight inches long
7 screws, multipurpose (drywall), one and one-quarter inches long
screwdriver, phillips
Wooden dowel, seven-eighths inch diameter, two pieces 2 inches long each (I cut off end of the handle from small-size toilet plunger)
Tools
Straightedge, preferably metal yardstick
Square
Measuring tape
Ruler or calipers divided into tenths of an inch, 2
inches or more long
Sharp pencil
Drill press (or hand drill) and seven-eights inch diameter wood bit, preferably a forstner bit.
Bit, clearance, for multipurpose screws
Wooden block for bending the wire, 2X4 four inches long or more
Clamps for holding the bender to a benchtop while bending the wire
