Tell Les that the recommended bend radius for 2024-T3 is 4T, where T is the thickness. So for 0.040, you need a 0.160" radius. What I've done is to bend up a bunch of angles out of flashing. Flashing is soft aluminum and will bend around a really sharp corner without cracking. The flashing I have is 0.010", and I bend it over in half to make it 0.020" thick. So on the first bend of the flashing, the inside radius is 0, and the outside is 0.020". Then I bend another piece of flashing around the first - inside radius is 0.020 (constrained by the first piece of flashing) and the outside radius is 0.040. So do this enough times and you have an outside radius of 0.160", and you can bend your .040" 2024-T3 around that. You have to move the clamping bar on top away from the bend hinge as you add those layers. The Hummelbird uses a lot of 0.040" for structural parts!
@@1bengrubb AC 43.13, table 4-6 gives the radius recommendations for different alloys, different thicknesses. 0.16 is what I bent all my 0.040" thick 2024-T3 to. It's a good rule of thumb.

Those bulkhead forms, like the bulkhead E form, should have a radius on it for bending the tabs.
Dang Brian I was going to fly over but I think you're about 2,000 mi away.... I picked up an RV 6 out there near Peoria

I'll ask him if the plans state a radius......0.16 is bigger than a 5/16 bolt that's huge
