Was able to cutout the two aileron spars and bend the rear, and flap spars. My back got to hurting or I would have finished the other two spars for the ailerons. It takes about 15 minutes to bend one spar from a blank. It is taking along time as I must tighten and loosen 15 bolts for each side. Plus to make the bend past 90 degrees I have to install the extra angle iron and clamp it for each side.
