Today I worked on the top lens mounting strip. I assembled the strip and mounted it to the wing skin. Before finishing I marked the start line for the bottom lens mounting strip.

I’m going to start today by removing the plastic covering along the rivet line of the leading edge skin using my soldering iron. Next I opened up the wing to work on the mount for the landing light and trimmed the protective coating around the opening so that I will be able to install the lense hardware. I removed the two outboard tip ribs and then using my forming dies I reversed the outboard stiffening flange on one of the ribs. Next I marked drilled and installed the nut plates. Finally, I reinstalled the ribs.

I filed the landing light opening to smooth the edges left from drilling the small holes. Next, I sanded the edges and used a bit of scotch brite to clean things up. I also used my soldering iron to trim the protective coating on the outside of the wing skin. Since I needed to open up the wing tip I needed to complete the holes in the inboard filler strip. I up drilled the pilot holes to #20.

Tonight I worked on cutting out the landing light hole in the right wing. I started by drilling a series of #40 holes. Next I used the tips of my snips to cut between the holes and removed the centre leaving the cutout for the landing light.

I finished transferring the #40 holes from the lower rear skin through to the rear spar. I also setup the wing to be flipped over in preparation for work on the landing light cutout

Today I finished drilling all of the nut plate spacers for the nut plates with the centered threaded hole. After completing the nut plates I riveted them to the first angle for the bottom rear of the wing tip. I have one more nut plate to attach to this angle. It is a nut plate with the threaded hole at one end. I need to make up special spacers for this style nut plate.

Today I continued to make the nut plate spacers. I made up one more strip of 5/16 inch wide by 1/16 inch thick strip and marked up the holes at 1 inch centers.

I worked at making the spacers for mounting the nut plates to the counter sunk holes in the wing tip angles.

I up drilled all of the holes on the bottom of the wing for the wing tip angles to #30. I also removed the protective plastic coating. Next I up drilled the holes in the top of the wing for the wing tip angles to #30 and removed the protective plastic coating. I then started to dimple the holes for the countersunk screws. I completed the all of the wing skins and the two bottom angles. The top angles will need to be done with a special C-clamp I made up when making the wing tip for the other wing.
