Hello Dave Snow:

I'm interested in constructing wing and stab jigs such as yours. Would you mind detailing the steps you took to get the parts ready for cutting.

I would think you would do a "top view" of all parts in CAD. Using the CAD length measurements for the ribs, you would then use something like Profili to generate airfoil "elevations" for each rib.

Do you then import airfoil "elevations" to CAD to detail all rib cuts? How do you determine rib cuts when the ribs are not perpendicular to the main spar? How do you determine the diagonal bracing in the aileron?

Being symmetrical wings, is it correct that you use the same top and bottom jig for both panels? I could see where two sets of jigs would be necessary. One top and bottom for rib and spar layup and a second top and bottom resized to allow for wing sheeting thickness. How many jigs do you use?

Thanks for sharing your experience.
