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.

Slick!
Thanks,

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

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!
