More parts!

The Flaperon Nose Ribs shown below are pretty small...about 1.5" tall with a tight radius around the nose. It took me a while to get the geometry on the flat blanks correct before they would form the radius around the nose without looking like a crimped bottle cap or cracking:

Generally, anything that has curved surfaces or complex bends gets formed around a form block. Other things like channels or L-angles can be bent up using the bending brake. For example, here is my rudder spar. It is the backbone of the rudder, and made up of .032" thick aluminum. It has 2 simple bends, but is about 4.5' long:

Looks like a simple enough part, but it took me a few hours to get my bending brake set up correctly to bend this properly. Plus, 60601-T6 aluminum is very stiff. It's a bit counter-intuitive, as aluminum is softer than most other metals, but it resists bending like crazy. So you can easily drill it out or cut it, but bending is another story! This really strained my DIY bending brake.
