42 more hours; learning to drill; debur and rivet. riveting is the trickiest; the right pressure setting; right hand pressure and alignment; etc. some replacing of poor rivets; a great kit though; and it is looking good. quite a bit of impressive engineering. the horizontal stab is almost done and lightweight yet seems very strong when assembled. Needed to get another squeezer and longeron head need to dimple more forcefully and take my time when rivetting; still waiting for my tungsten bucking bars for the tight spots.
