Drill jig(s) for drilling seat hinge stock.

[Philip Cobbin]

These jigs were used for the repeatative (ie. invitation to mistakes)
hole patterns that have to be drilled into the hinge stock for the
seats. Three jigs are required. They are straight forward to construct using a 1/2 end mill. After the holes are drilled in the hinge stock the drill can be run the other direction to match drill the F-742 aft seat floors etc.
