Brief Description: VS Riveted on the rear spar and complete
|
|
I squeezed all the rivets for the rear spar. Don't forget to leave the 10 holes open for the fairing later. If you put rivets in there now, you'll end up with photo 2, below. The secret to successfully drilling out rivets without enlarging the hole, nor damaging the skin is drill exactly in the middle of the rivet. Or as close to center as you can. One technique I've found is holding the drill in the center and turning the bit by hand to make a little indention. I don't like hitting it with a punch because you can deform the skin. Then I turn the drill really slow, under power, and you can steer it a little as it starts to drill. Anyway, rule one is still, "don't drill out rivets but rule 2 is drill them out if you must, and if you, do it very slowly and carefully and get the drill bit down the middle as much as possible, and just the right depth, the heads do pop off and the shafts do push out. Oh, two more things, 1) Stop pounding with the rivet gun the moment you notice something not going right. And 2) if you do enlarge the hole don't forget OPPS rivets with the 1/8 shaft and 3/32 flush head. VS is complete.
