Wing jig
harold hogan:
Bought a Brodak Cardinal which has a 54 inch wingspan. I also have the Brodak wing jig which I haven't used yet so I don't have any experience with it. The jig isn't long enough to do the whole wing in one piece so I'm assuming I will have to construct each wing panel individually. My question to the experts out there....how can I attach both wing panels so that the wing remains true? I guess I could shim both panels and use a straight edge to check for alignment but how would you experts do it? Thanks

What does the Brodak jig use for rods? I have never seen one. First thought is to purchase rods that are long enough. Second thought is to build each half to a certain point, then join the panels using the jig and rods in the center to align the haves, as long as you know you will be able to slide the rods out.
Welcome to the party pal!!
HAPPY NEW YEAR!!

It is easy to use the jig parts you have and make a bigger/longer wing jig. Do a search through the builds and you can get an idea of how to make one. H^^
Tim Wescott:
Using the jig you have, get each wing half built, then slide the rods halfway into each one and build the center section.
The Brodak wing that I built has 5/16" jig holes. That's an almost exact match for 8mm carbon fiber tube. So, find a kite shop (I like Goodwinds) that sells six-foot long 5/16" (0.313") or 8mm tube (or rod, if you don't mind heavy), and use that with your existing jig pieces.
I just used the 8mm tubes and 1" thick aluminum spacer blocks on a flat building board -- that's enough of a jig for me, and I seem to be building straight wings.

Thanks guys, good advice. I think investing in longer rods would be the best solution. Building both wings and then supporting both wing panels with the jig in the center should work as well providing the rods are easily removed.
