Riveted the 412 and 413 hinge brackets to the spar and then I ran out of 4-5 rivets....guess I and been practicing too much!!!! Then I bolted on the 411 hinge bracket and torqued it down to specs and added some torque seal. then I added the 810 amd 814 to the front spar. the squeezer wouldnt work to well for this so I fugured now was a great time to practice with the gun and bucking bar. Only had to drill out one rivet which went really well!!!! Then I decided to needed to order some 4-5 rivets and a offset rivet set.....the 404 and 405 rib seem hard to reach with the squeezer without bending back the ribs.
