Bent HS front spar angles

After spending almost a week in Germany and a couple of days at CERN, I'm back home again and even brought a cold as souvenir. Not much progress on the plane, but at least I bent the HS-810 and HS-814 angles. The plans call out for a 6 degree bend at 4 7/16" from the center, so I first marked the center and then the bend lines. With a 3/8" radius and 1/8" thickness the setback at 6 degrees is fairly small -- little less than 1/64", so I clamped the workpieces in the vise with the bend line just above the wood block:

Then I bent the angle by hand (no mallet) little by little and checked the progress with a cardboard template. It took some time, but I like the results:
