Default Cowl/Firewall Hinge Pin Retention

Is it necessary to, and if so how do you retain the hinge pins on the cowl to firewall joints?

I stole this idea...here's how I did the top cowl to firewall pins:



And here's how I did the lower cowl to firewall pins:


Might be hard to visualize that last one, but basically I bent about 4" arms on the tops of the pins, and the arms tuck under those little clips along the cowl hinge.

Nothing moves anywhere that way.

This is how I hid my hinge pins. CAMLOCS, and they are great.

Default Top Cowl Hinge pin retention

While I was at OSH this year, one of the things I paid particular attention to was the solution various builders used to retain the cowl hinge pin.

Here are some examples:


For those that are using/have used the stock hinges, any additional ideas on how to retain the cowl hing pin?

I don?t see an example of ?doing it per plans?, which uses a hinge eyelet (well on the RV-7 plans anyway).

I have also seen metal 2d sculptures (like an art deco eagle heads for example) holding the pins in place.

I am sure you have thought of this but one advantage of the external retainer over a flush retainer is that you can install a quick and dirty retainer and get you plane in the air sooner. Then work on your master piece when your plane is flying. Good luck and have fun

I bought the hinge pins with the stainless "hinge loop" already welded on the ends....coudl have done something prettier, but Hugh is right - it got me in the air quicker!
