Starting on fuselage. My plans say to make blocks. They MUST be 1.438 inches to match the thickness of the spars. Just happened to put a dial caliper on the spars. Well, they all read thicker, The thickest reading.....1.448. .?????. How once everything is locked down and riveted, can a solid piece of metal that is larger than the hole it is supposed to go in, actually go into that hole. So, how did you'all do it. Your thoughts are greatly appreciated.
