I am purchasing a lathe mill with 4 axis CNC capability and will be building parts including the wing attach. When do you need them ?

Thank you all for your thoughtful replys. My name is Windy Farnsworth for those that want to know. I will be match machining the pins to match the taper in the Ti. There is a man in my EAA club that makes very high precision parts of the same size as the taper pins. Hand lapping is a good idea, but unless the pins are to be placed in the same hole they were lapped in, the utility might be lost. A The parts need to be machined to match at very high tolerance to prevent fretting. The surface finish should be good. I will have to look at the GE design practices for rabbet fits and see what it says.

Hangar Flying / Varieze Wing Attach
« on: January 04, 2011, 02:54:46 PM »
I am nearly finished with reverse engineering the varieze wing attach fittings. I am interested in finding out what other people have to say about them. I am proposing to build my own, made of grade 5 titanium 6AL-4V. Titanium is stronger than 2024 aluminum, and nearly immune to corrosion. The pins will be made of Inco 718. The bolts will be Inco 718 as well, since cadmium plated steel is not recommended against the titanium. Questions:

1) Is there other things that should be changed, or is the material change sufficient to overcome the problems with the current fittings ?

2) Are there other builders that would be interested in titanium fittings for new builds or replacement of existing fittings ?
