I'm building a bending brake for the leading edge skins. I tried the vacuum forming method, but it didn't work out perfectly for me. I liked the sound of how this one works. More to come.
Building and using it can be found at: http://n36sx.com/wings/press.html http://n36sx.com/wings/index.html
The "base" made of a 2x8 and two 2x4's.
Tick mark is the center. Other red lines are 15/16" each side of that tick mark.
