Bending Aileron Skins March 15th, 2009
The aileron skin needs to be bent to a fairly small angle before it can be assembled. Van’s recommends using a bending brake made out of 2×6 lumber. This is what I did for the elevators, but that was over a year ago. The wood became so warped I had to make another one. This time, instead of pine, I used MDF. I had some 2’x4′ MDF laying around, but I needed the brake to be just slightly longer than four feet. Rather than go out and buy a huge 4’x8′ piece, I made each section of two pieces, two layers deep. So, each flap is 1.5 inches thick, and 60 inches long. Because it is MDF, the brake is heavy enough that it won’t slide around like the 2×6’s I was using before.
The brake is so long it was much easier to have two people pushing on it to get a uniform bend. So, Fabiola got on one side and I got on the other, and we laid some weight into it…
