(page 8-03) Thought I'd killed a part..........

....which, of course, would require that I order a replacement from Van's.  I've avoided that particular embarrasment so far, though I'm sure it'll come. The skins and ribs for the anti-servo tabs went together easily, as expected, as did the horns, which required squeezed, counter-sunk rivets.  Ah, but the piano hinges.  The drill guides (the blue pieces in the photo) are designed to fit tightly into the hinge eyelets, providing a guide for drilling the holes in the correct places in the hinge.  Each guide has two rows of holes, to be used in two different steps.  With a little thought, it's clear that only one of the rows should be used.  I snapped the guide into place, clamped it down, and proceeded to drill the first two holes, one in each row.  After inventing a couple of new swear words (the normal ones being inadequate for the occasion), I realized that the mating part of the hinge on the horizontal stab (to be done later) needed to be cut an inch shorter than the one on the anti-servo tab, so I could cut off the mistake when I get to that step.  Whew!

Another issue involved the repeated drilling through the same hole in the drill guide.  Using the pneumatic drill, which spins at very high RPM, the hole in the guide enlarged with each hole drilled in the hinge.  The result was a bit of variation in the position of the holes.  This may be a problem when it comes time to rivet the hinge to the pre-punched holes in the skin.  I switched to the battery-operated drill, spinning at low RPM.  The drill guide clearly should have been made of steel.
