And that is almost how they are done on the Mustang 2. Those without folding wings use a bolt and nut, but when using folding wings you use a bolt ground to a bullet shaped end instead of threads and just bang it in the hole. The wing gap seal has a piece on it that keeps them from being able to back out.
However, on the KR I do recommend a nut and if you are putting it on might as well torque it correctly. Since you have two relatively thin WAFs that can be bent a bit it is best to have them clamped together so the bolt is really loaded only in shear as designed. -------- Original Message -------- Subject: Re: KR> Reaming WAFs From: Mark Langford via KRnet <krnet at list.krnet.org> List-Post: krnet@list.krnet.org Date: Sun, August 30, 2015 3:59 pm To: KRnet <krnet at list.krnet.org> Cc: Mark Langford <ml at n56ml.com> Although I'm certainly not advocating anybody do this, you could likely fly around with cottered pins in place of the bolts to keep them from sliding out of place, and you'd be fine. I'm pretty sure there are airplanes and ultralights that use simple pinned joints.
