The final exercise for today was to make the angles that attache to the horizontal stabilizer rear spar. These required a bend with an inside radius of 1/8" tangent to the inside radius of the angle. To bend this I found a screw driver shaft that was the correct diameter and clamed the angle to a plate in the vice. Next I attached a piece of hardwood to provide the leverage for the bend. This seem to work okay but it did cause the angle to bend a little on the adjacent leg. I solve this problem with a few blows from my rubber mallet after the initial bending.
