Flap Brace R/H W-821

The Flap Brace W-821 is NOT fully pre-punched and the 'wing' flange needs to be measured out and drilled accordingly. I then used this 'drilled out' brace as a template for the other lhs brace and also to align prior to drilling out the trailing edge of the lower wing skins which were also NOT pre-punched.

As a precaution, after marking out the 1/4" edge distance I also used a spring punch to ensure I did not drift off with the drill out.
