Study your plans as some ribs will be constructed without gussetts on one side or the other, such as tip ribs and root ribs. Shown below are some of the components that go into the rib jig. Clamping blocks are cut from suitable wood. Pressure is added and released with the wingnuts. Studs are a furniture screw that have wood screws on one end and machine treads on the opposite end.
Cam action locks that hold and release rib stock material are sections cut from a large dowel rod.
Use paste wax and small strips of wax paper as release agents protecting the jig from excess epoxy. All clamps and plexiglas pressure blocks were numbered to match a specific location on the jig. This was a time-saver when matching the correct size plexiglas block to the gussett being glued. TIP Gussetts were cut in bulk prior to building, then stored in numbered compartments. We found this to be another great timesaver.
