Have you tried to form the curve around a cylinder? I found that I could test a scrap piece of Alumn. You know, form it around a cylinder of a given dimension and then check the results of the scraps curvature radius against my desired radius. I then would adjust my cylinder diameter and test it again on a new piece of scrap until I got the diameter I desired.
I made that cylinder diameter adjustable by wrappping a cardboard shipping cylinder with I think felt I had on hand. It was quick and easy. 2024-t3 Alumin work-hardens, so if you sneak up on your desired radius, it will require a smaller and smaller diameter to get it to move. So Finetune your cylinder so your scrap can bend from flat to your desired curve with one motion. In otherwords, don't sneak up on it.

Good job at keeping a sense of humor through some “not so fun” tasks! I have to re-learn that once in awhile

Safety wired all but two of my turnbuckles today as I am buttoning things up. As I am sure many of you can commiserate…. I lost the will after a while and I just did not feel like removing the floorboard under the pilot seat to do the elevator, the remaining one is the aileron pass-through and I have a reason (more to come later) for waiting on that one. Here is a photo example

I also started the fuselage to wing fairing today.

While those are a perfect fit, I am going to change from .025 to .016 or .020 for a more efficient curve on the leading edge. Yep…Imagine that doing things more than once

As posted above I have been working long hours everyday and today got the flaps (yesterday on the flaps) and ailerons all done. The ailerons are super light to the touch and have no side to side slop at all, I was really happy with that! Turnbuckles just above the triangle need a few turns to take out a bit of slack. I had to put a bit of lubrication on the right flap torque tube and that eliminated a bit of a slow and not quite complete retraction. Being I was doing it I did the left as well and now both spring (pun intended) back to full retraction.

I was too busy to take photos today, but both ailerons and both flaps are hung. Flaps are set to the wing using the springs and rod ends… aircraft spruce SCREWED me and is delivering my shackles two days later than the shipping I paid for. They arrive tomorrow at some point.
Then I will set cable lengths and nicopress the cables, adjust the turnbuckles and the start on the aileron cable rigging

Past several days were spent wrapping the ends and pockets for the 2nd Flap and Aileron.

Then I undertook actually covering the aileron

Then today I hung the right aileron IMG_6489.jpg
Left Flap covering starts tomorrow, likely will take 2 days, possibly 3, once hung it is on to rigging

Glare shield covering nearly finished, just a bit of trimming but ran out of time…. Headed to Korea for a week
