Firewall forward, finish, cowling installation

Top cowl right side Camloc grommets and studs installed.

Camloc receptacle riveting in progress.

Camloc receptacle riveted completed.

Well, all but one came out nicely. For whatever reason, the marked (and unsecured) Camloc just wouldn’t engage with its receptacle. Either it’s defective or the its hole was slightly off target, which is much more likely. I’m going to acquire one of Skybolt’s floating receptacles and replace the standard one in that location. Hopefully, that’ll solve the problem.

I’m not thrilled with the gap between the top and bottom cowlings (on either side), though I’m optimistic that paint will fill some of that gap along the split and that a little fiberglass work will reduce the gap at the front.

Oh, well; onward! 

Left side marked for drilling.

Top cowl left side Camloc grommets and studs installed.

The left side came out better, though there’s still a slight gap present, both at the front and along the length of the side.

As with the other side, paint and glass work will cover all sins.

I still need to do the nutplates behind the spinner, the interior epoxy coating, and the top cowl air ramps. The cowling is rock solid as-is, though, and completely airworthy. Overall, I’m satisfied with the effort and glad to be free of hinge hell.

Bottom cowl held in position by one Camloc on each side. My alignment marks (for vertical orientation) can be readily seen on each side. These were made prior to removing the upper cowling.

Complete cowling in place with all firewall Camlocs locked down. I’m fairly pleased thus far.

I couldn’t resist setting the spinner in place for a quick photo or two. Looks good!

Bottom flanges for lower cowling drilled and clecoed in place.

Bottom flanges for lower cowling deburred, countersunk, and clecoed in place for riveting. I strongly suspect that they’ll need to be pop-riveted (I’ll find some Cherry rivets which fit) due to conflict between the squeezer yoke and the engine mount.

Yes, I could try to grind down my no-hole yoke, but I’m not interested in sacrificing a $125+ yoke for this one-off task.
