I begin fabricating lower cowl aft support bracket. A slot has been cut in the cowl to allow some space for the nose gear and the slut will be covered by bracket that will also add some strength to the cowl.
The picture shows some parts assembled and drilled. The two larger sheets will clamp the cowl into position.

The lateral hinges will get riveted today, as I stillhave some proseal left over I'll use it as it's a very good adhesive. So the dreaded black stuff is back.
It takes quite some time as all the extra holes have to be filled.
A view from inside.



And a more pleasing view from outside.

Before enlarging the holes for the camlocks, I first drill holes along the firewall and into the camlock strips that will allow the cowls to be clecoed to the fuselage,. The camlock holes will be too large to be used to hold the cowl tight as I don't want to install the camlocks now.
The extra holes will be filled during the finishing.
This is the center support strip with the silver clecoes in the extra holes and the camlock holes enlarged to the need size for the cowl side.



Here one of the screws (temporarily) in place.



The holes in the strips are the drilled too a larger diameter. On the left before drilling with the template in place, in the center after drilling and on the right with the receptacle in place.



The receptacles are riveted with countersunk rivets, so the strips have to be countersunk.


The same has to be done on the strips for the lower cowl. Some less work as the strips are straight.
On the picture you can see the three extra holes and the size difference of the holes in the strip and in the cowl.

It is suggested that the hinges be glued and riveted. So that the glue gets a better grip, large holes have to be drilled between the rivet holes. I decide to drill a bigger hole every two intervals so as not to weaken the hinge too much.
Then I countersink the rivet holes on the cowls (not less than 124 holes).



As I will glue the hinges another time, I begin by preparing the camlock strip. The rivet holes have to be drilled using the template included in the kit. Nothing difficult but again a lot of drilling (33 camlocs, so 66 rivet holes).

I begin by preparing the side piano hinges, I leave them a bit too long for the time being. I drill the rivet holes every inch.
The holes are deburred as is usual.



Then I drill the pilot holes for the screws in the inlet area. The holes will later be enlarged for the screws.



After some more tweaking of the gaps between the different parts, I can begin the match drilling of the lower piano hinge. Nothing difficult here.



Then I drill the upper hinge. Antoine came to help me light the interior of the cowl so I could make out the pre-drilled holes in the hinges.



Next time I will have to countersink the cowls, glue and rivet the hinges and then drill to final size the camlock holes.
