In truth, he told me back in the early fall that he recommended that all Corvair engine builders use nitrided cranks. At the time, the full set of data had yet to be compiled, but as a minimum it provided a good measure of safety. The newsletter on the 15th, is essentially a summation of his research in the area and the issuance of an actual AD.

I believe that Zenith did change to bolts for the upper rudder hinge attachment. Also, somewhere I remember reading that the vibration/shaking from the starting and stopping of the Rotax 912 can cause some problems with the tail. Chuck D.

I received many good suggestions. The most important may have been to make sure the main spar was not bowed as well. It was - *I think.* Anyway, this investigation has led me to the conclusion that it might be best if I can build a jig on my table to which I can clamp the main spar - and perhaps the rear spar as well. Obviously it is not sufficient for me right now to just have everything sitting on steel beams. (I don't know whether it matters or not, but I bought the wing kit from an earlier builder, and the unopened crate had just been sitting for about two years.) So, has anyone crafted some type of jig and can you give me advice on how to build it? Needless to say, it would be nice if it were reversible so that I can use it for the second wing. Thanks, Michael ________________________________ Message 9 _____________________________________ Time: 04:08:10 PM PST US From: Paul Mulwitz Subject: Re: Zenith-List: Wing Jig? --> Zenith-List message posted by: Paul Mulwitz Hi Michael, I don't have a jig, but I do have a different way to use the workbench which might help. I have a wood (particle board) bench with 2x4's on edge going across the bench. I am not sure how many there are, but it must be around 6 or so. Each one is screwed to the bench and shimmed so the top edges of all the 2x4's make a level work plane. I place the wing on the 2x4's and then use blocks screwed into the bench or 2x4's to adjust the location of the wing so it is level and at the right angle (specified in the drawings) for construction. After the ribs have been squared the whole thing is locked in place with blocks again. This keeps it all in a nice rigid position for attaching skins. It is all a variation on using steel beams with wood replacing the steel. The wood is a lot easier to fix in place with screws. Good luck, Paul XL wings > has anyone crafted some type of jig and can you give me advice on how to >build it?

You need them to build it, and study them first, so you dont beguin replacing parts. The building Jig you need is a straight table... Works for both wings and the fuselage. Saludos Gary Gower.
