I’ve been debating for a long time how to deal with these very heavy angles that support the cockpit’s real roll bar. They’re supposed to be riveted in place after the fuselage skins are completely riveted in place, but access to the them is limited once the canopy rails are riveted. And unfortunately, the canopy rails need to be riveted to fit the canopy.
So I’ve elected to do what a lot of other builders have done, and relieve the outside edges of these angles to accommodate blind rivets in the side skin holes that are blocked by the angles.
A little work with files, sandpaper and scotchbrite did the trick.
