February 28, 2009: LONGERONS Continued!


Page 22-02 continues! Deburred canopy decks. Then used a piece of scrap .025 thick aluminum to simulate the side skin and clamped the deck to the longergons. Matched drilled through the deck into the longerons. To keep the drill perpendicular, I monitored the reflection of the drill bit which should appear straight, if it is perpendicular. Dan Benua gave me this tip and it works well. I then took things apart, primed the longerons and left them to dry.

Now here's the question. Step 4 tells you to produce a curve that matches the canopy deck template "within a sixteenth of an inch. I did this, but when using the scrap aluminum to simulate the side skin, I see that the deck overhangs the skin by the 1/16 inch mentioned earlier. I hope this is within tolerance. I'm going to call Van's tomorrow to ask. My plan is to take a vixon file and shave off the excess overhang.
