Default FWIW

I insert my pins from the rear. There is some extra length and it's bent 90 degrees for about 3/4". I release the 1/4 turn fasteners on the sides, pull out on the sides of the upper and lower cowling and insert or remove. The bend keeps it from migrating aft. Nothing shows, nothing in the airstream. I lube the wire with hard soap.

I have a loop of wire with a handle as a removal tool and a fiberglass pusher for insertion beyond the line of the seam. I keep them in the airplane in case I have to remove the cowl away from home.

I would do it again.

A very simple and neat solution is making 3/4 of an O with one pin end.
You screw two screws on a wood bar and then insert between them one of the pin ends. Then pull the other part of the pin to form the O.
Insert the pin in the hinge and make a hole on the cowl. Installa platenut.
Gently bend inwards the last portion of the pin, to accomodate for the cowl profile.
Next week some photos.

Default My covers

The first photo was taken when I WAS INSTALLING THE COWL IN 1999. The covers are made of 0.016" 2024-T3. They are each mounted with 3 #8 flat head screws and platenuts. Originally the platenuts were all mounted directly on the cowl fiberglass inner flange and the two outside fastener locations still are but after a couple of years of operation one of the inner locations gave out and I had to install those two inner fastener location platenuts (one for each cover plate) on a backing plate of 0.032 2024-T3 aluminum. No problem since then. The second photo was taken on 6-22-2007 when I was experimenting with inlet size reduction plugs. The inboard mounting screws for each coverplate go through both the upper and lower cowl interface. The cowl outer surface is countersunk and the cover plate holes are dimpled.

I duplicated the cover Wayne did on his award winning 7. I saw him removing the cowling for judges and took couple pictures









I spent couple evenings on them. Printed first picture full size copied the cover then made it. The method is written on Walter Tondu's website.

The Rv-7 cowl pin covers aren't on the web site just yet, but I've seen them for both the 7 and 7a.

They should be up on the site soon.

Here is the photo. Photo is ugly, cowl still not finished and painted.
But you get the idea.



And this is an ugly detail of my nearly finished cowl
