Mostly, I had the shoe slip on one aileron spar, and it ended up being .035 narrower in the center than the outside so I will be remaking it. Afterwards I found it necessary to use a rubber mallet to seat the shoe each time I clamped the blank into the brake. Using this technique I was able to get extremely good bend consistency across the entire spar. Most spars are at 1/64 of an inch variance of width across the length of the spar. The worst spar was 1/32 of an inch variation as measured on left, right, and center. I found that clamping the outside bends on the trailing edge was difficult so I removed the shoe and bent without it. I did not change setback and since the bends were shallow angles they turned out with a good radius.
