Aileron - Flap hinge fabrication

[Olibuilt]

I need about 12 aileron - flap hinges. I have a few left from the crashed plane but I need more (3 per flaps and ailerons). At about 100$ each for the stock ones, I was thinking making them. Or is there a cheaper$ experimental alternative??

Should I copy the stock design, and make them by bending some steel?
What about using stainless steel about the same thickness?

Thanks

Olibuilt dont use s/s on any thing that will contact aluminum it will cause corrosion and these thing are bolted to the spar.

You might check with Javron

It's not bad and you can save a little. If you use the traditional super flap false spar, there is a slight difference between the flap and aileron hinge brackets that the eye won't pick up. Watch those prints.

Good luck

Stainless steel(most grades) are very close to most grades of aluminum as found on aircraft(2024, etc) on the galvanic corrosion chart. Which means corrosion is minimal and a good coat of zinc chromate primer is all thats required on the aluminum parts. I would not hesitate to make them from say 304 SS.

There is a slight difference in the aileron hinges and flap hinges as Iflylower indicated.
