Making a doubler for the F-721D attach angle - 2 hours

 I just cant bring myself to riveting the attached angle on to sloppy holes, and I also dont want to risk re-drilling new parts through existing holes on the longerons. So after discussing options with a fellow builder (Mike with the Stewart S-51 and F1 Rocket) I figured it best to simply fabricate a doubler for the F-721D attach angle. I pulled out some 0.040" scrap and sketched out a quick shape. I then used the proper right side attach angle to drill new crisp #30 rivet holes. Then using an edge distance of around 0.25" I located two #40 holes to attach the doubler to the forward canopy deck. On initial fit, I see that I have to trim a small angle to clear the inside radius of the canopy deck. Also I need to trim the doubler to clear the longeron.

Once happy with the fit, I committed to drilling the two #40 holes in the forward canopy deck. 

Re-clecoed the forward canopy deck into the fuselage and verified fit. 

I am pleased with how it turned out (not pleased that I had to do it in the first place). I then acid etched the doubler and primed it. After a few hours dry time on the primer, I then riveted the doubler and the F-721D attach angle to the canopy deck.
