Fuel Valve, nutplates, etc

Fabricated a bracket for the Andair fuel valve. Instead of nuts on the backside, I used nutplates.

Also spent quite a bit more time than anticipated installing the nut plates for the left and right covers.

Not many pics, just this of the fuel valve plate.

Cockpit Floors part 2

Only a single picture, but more work on the cockpit floors today.

Got all the stiffeners fit and match drilled. Put the seatback hinge in place and match drilled. Fit a spacer for the hinge between the floorboards where they overlap, so that it doesn’t bend the hinge.

Now I can take the floorboards, prime the underside along with the stiffeners before they get back riveted on.

Also riveted the footwells together. The longeron yoke worked great for all but 8 rivets, so those had to be bucked with the gun and bar.

Finished match drilling most of the floor boards, and started adding the nuteplates inside the fuse.

I found the best way to set the nutplates was to put the screw in from the back side, one cleco in the hole, drill the first hole and then swap the cleco.

  

The nutplate for the Flap Bearing Blocks was a huge pain. Extremely hard to get a countersink in. Wish someone had a better solution for this.

Fuse Work

Got the fuse mounted on the rotisserie today. This will definitely help to make it easier to work on.

Did more work on the floor boards today, including working on the flap actuator and  F-445 Flap Bearing Block. I had an issue with F-445 fitting, and it turns out on the Quick Build that the factory did not put adequate clearance on the F-8578-1 Seat Belt Bracket. I removed the brackets and radiused both of them per the plans. There were no issues after that.

Trim Tab Riveting

I started to rivet the trim tab today. Because I chose to use the riblet method and face the flanges inboard, I have to use blind rivets on them. Got to the hangar thinking I had the right ones, but I didn’t so I had to order a few.

Riveting the tab’s spar to the bottom skin looked like it was going to be a challenge, but using the longeron yoke worked perfectly. I ended up having to buck a couple of the trim tab horn’s rivets, but they came out really nice.
