Trailing Edge (1 hr 15m)

Final thing to do on the bottom of the skin before I can rivet is to locate the trailing edge skins and drill the appropriate holes. First step towards that is to drill through the pre-drilled holes in the bottom skin into the rear channel.

Then I slid both trailing edge skins under the bottom skin and aligned both sets of pre-drilled holes with the ones I just made.

I then opened up all the holes in the trailing edge to size 30 for the now famous A4 rivet.

Here’s a closeup of where the two trailing edge skins are joined

And that completes this portion of the bottom skin. Next up, a lot of deburring and then we can reassemble and rivet.
