You have no idea . . . I've tripped over this thing twice and my dog thinks it's a huge pillow. sign1 I have decided to wait on the rest of the reinforcement boxes until I finish the hangar bay, because I'm tired of big parts and want to work on some minutia(plus . . . I ran out of thick cardboard and I don't want to laminate the pieces that many times. ) So to begin with I'm starting to construct the paired cylinders on the hangar roof that support the rail system on which the crane moves. The starting point would be this Q-tip: Well, 30 or so Q-tips to be precise. I took an Exacto and cut the cotton off the ends of five of the Q-tips and discarded that (though in hindsight, with the amount of cotton I recovered I think I could knit a new sweater). Then I cut a slit down the lengths of the shafts until I got past the glue that holds them together. After I got to a suitable depth I peeled the excess off and glued up the loose ends. After I got those done I marked how long the parts are in the photo and cut them all to that length. When that was done I glued pairs of them together. Not all the lengths were even because I think I may have added a millimeter or two along the way. I'm now in the process of gluing strips of paper on the ends of the pieces: I can't wait to get past this and start in on the rail system, because after that I can glue it into the hangar and get to work on the fun part: greebling the hanger bay!
