Default Tip: Show us your cowl / hinge pin cover or method to secure pin

Hello RVers,

I need some help trying to find out a link to a series of pictures I've seen some time ago, showing how different builders had solved the problem of securing the cowl hinge pin. I think the pictures were taken at some fly-in, but I can't relocate the page, even after googling with different keywords.
Maybe the author of this page will read this...

Thanks a lot

Default What's around the firewall?

Are you using hinges or "skybolts" around the firewall?

Default Not for a VAN's

Sorry I didn't mention that at first, but my question is not for a problem I'm trying to fix on my -9A project, but for another one where I'm part of a builders team for a Jabiru J400.
The top and low cowls are joined with a hinge, like on standard VAN's cowls, and I'm trying to bring some examples of how to secure the hinge pin to my teammates.
I'm far far away from reaching that step on my -9A

I'm really happy the way they turned out. You hardly notice them.

Default Hinge Pins

I could send you a picture of mine but you wouldn't see the cowl hing pin tab!

My cowl pins are inserted from inside the fuselage.

A short piece of 3/16" stainless brake line is inserted though a small hole in the firewall that is aligned with the hinge and extends into the cabin. The line acts as a guide for the pin and is epoxied in place in the firewall and a clamp holds the other end in place in the cabin.

The pin is inserted from the cabin, through the brake line and then into the hinges. A little pushing and twisting on a plastic knob that is epoxied on the end of the pin allows it to slide right through the hinges and into place.

Extra care is needed when the hinges are attached to the cowling to ensure the hinges don't bind later. Grind the pin end to a dull point so that it slides into the hinge more easily.

I had heard from other builders that this technique would require two people to install the cowling (one to position it in place and the other to install the pin from inside the cabin). Not so...... If care is taken during the installation of the hinges, installation or removal of the cowling top is a one-person task.

Default Mine are hidden but differently

Mine are inserted from the aft edge by pulling out the sides a little. There's a right angle bend in each one at the back end. When they are fully inserted I close up the rest of the cowl along the firewall with skybolt style fasteners. I did not want a hole in the firewall, so this is all done externally. The bent leg clears the camlock but is stopped by it so it cannot work back and thus below the flange. Removal is accomplished with a wire loop on a bolt shank. Pics and details on request. I don't think it's any different, but it's a SJ cowl.

Default Thank you!

Thanks a lot for all your answers. I just had a message form our builders team leader, and after reading many comments on this forum, it seems that we'll go for Camlocs

I think this is the way I'll also choose when it's time for me to work on that part of the project.

For now, I've just played with the tools by building the RV Training Project and the nice Toolbox, waiting for a replacement for some empennage parts that have been damaged during transportation to France

At least I could buck my first bad rivets on test metal...

Cheers
