RE: Building a built-up pattern stab and wing
Gluing in the shear webbing, cutting the sheets and adding the leading edge sheet, setup and gluing the socket in the panel.
One of the pictures shows how much material needs to be removed at times to straighten the sheet edge.
The jigs have all the rib centerlines the same distance from the table top so to set the dihedral the tip is blocked up and the tube is set parallel to the table. The frame/jig is placed over the plan to verify the real tube is aligned with the plans tube. After the dry fit the pieces can be glued together, I used the Poly-U this time but I've also used 30 minute epoxy at times.
One issue that I've had is with the plans; they are never printed to the exact full size, with the jig this is not a big problem because the jigs are the full size and the plan is used as a reference when building the jigs to get the proper geometry.
