Finished Flaps and Other Stuff

I finished up the flaps on Saturday. These were a really easy build and they look great. I riveted the trailing edges with proseal and with the rivets altering directions, facing up, facing down, facing up.... I did this to prevent any warping in the part during riveting. (I also did this on all the other trailing edges I have made, so nothing new). I laid some blankets down inside the fuselage and stored them in there for now.

Saturday June 15th - 4.25hrs - Finished Flaps, Riveted trailing edges.
Sunday June 16th - 5.25hrs - drilled skins, pitot tube mount, drilled holes for pitot lines, installed fuel tank

Finished Flaps Total Time = 26.25hrs

I installed the LH Fuel Tank yesterday, RH will come later. This was easier than what I thought it was going to be. I imagined lots of sweat and grunting to be required, but everything lined up really well. I first spaced them up using boards underneath the jigs they were sitting in and then after lining up the first hole I inserted a cleco into the nutplate to hold that end. I then raised the other end and did the same. I few more clecos and everything was lined up. Then I started installing the 56(?) screws...there were a lot.

I drilled out the LH skins and I got some help marking holes I drilled. Then we did the big cleco migration, where every cleco moves over one hole, to final drill the unmarked hole it was previously installed in.

 

 

 

The pitot/AoA lines are installed. I am using the Pitot/Static kit from SafeAir1. It provides tubing, connector, etc for cheaper than if you buy the stuff seperately (trust me I researched it). The tubing is nylon and can withstand -40F to 200+F, very durable. I had to drill new feed through holes for the green line, which will be my pitot line. The blue line will be my AoA line and I used the existing feed throughs made per the plans.

 

 

I worked on my pitot mast installation. I am using the Gretz pitot mast kit to install the Dynon pitot. The instructions for the install are decent, but it leaves a lot up to you, which was fun.

I used an old rib part I messed up on to scavenge an angle bracket.

Here are the 2 main parts. The angle bracket and the backing plate. (Note: This pic was post drilling, the parts don't come with holes)

 

I match drilled the backing plate to the spar first, removed it, then clecoed the skin in place. Reclecoed the plate to the spar on the outside of the skin and with the angle bracket clecoed to the spar I match drilled through the plate, skin, and bracket at the same time.

A picture with the parts clecoed in place. The skin will install over this.

I am installing in the third bay from the wing tip on the outboard rib.
