Cold morning - 16F. Even with the heaters on I could see my breath. I studied the plans carefully before touching metal. My buddy Mike had given me some pointers about tweaking the flap brace flange. Like the aileron brackets, there's a combination of standard and flush rivets so care must be taken. I oriented the braces, trimmed per the plan on the inboard in to clear the rear spar doublers. I cleaned up the trimmed area with the 3M wheel on both left and right braces. I then cleco'd them to the rear spar (left/right wing) and match drilled #30. I then removed them and drilled out the flap brace-to-skin holes to #40 (those will get countersunk). Not blazing speed, but good progress overall for an hr.
Trimming the flap brace per the plans.
Cleaning up the edges on the 3M wheel.
Here's the flap brace installed on the left wing. The bottom skin comes dones and rivets to the brace.
