The alternate method (not using tank dimple dies) indicates a couple of turns with a de-burring tool in the skin to make room for Pro Seal under the rivet. After helping a couple of people build tanks, I have learned that the Pro Seal goes EVERYWHERE...on the rib...on the skin where it contacts the rib...in the dimple depression before inserting the rivet...and you even dip the rivet in Pro Seal before inserting and squeezing or bucking.

I've finished riveting my tip-up canopy frame together and have the canopy all drilled and temporarily attached. The problem I have is that the canopy is flexing outward so that the frame overhangs the side of the fuselage. On the pilot side it sticks out 7/32", the passenger side is even worse. I expected some amount of this but not as much and I really don't like it. The problem is more along the middle.. the aft edge lines up nicely. Have others had this much of an overhang? Anything you can do to reduce it? Since the canopy is all drilled and ready I can't do too much for fear of misaligning the holes. Possible options: 1) Attempt to bend the frame in at the midpoint enough to allow the sides to line up once the canopy is screwed on. 2) Heat the canopy up enough to take out the outward flexing tendency. (Dangerous!?) 3) Install some sort of pin on the bottom edge of the canopy rail that engages some sort of hole in the canopy deck that would pull the sides in when closed.

Just a word though, before setting the rivet, wipe the ProSeal off of both ends of the rivet so that the rivet set and bucking bar should not slip.

This will be one of those jobs you will love when it is finished.

I cut a bunch of paper shop towels in four pieces or about 4 inch squares. They were real handy and I didn't waste nearly as many towels. This is one of those jobs that the cleaner you keep everything the better off you are. Laying down butcher paper on the table was another good thing. It made clean up a lot easier. I have finished one tank and I'm not dreading the other one as much as I thought I would.

Ice" Subject: RV9-List: leading edge to fuel tank difference --> RV9-List message posted by: "Michael T. Ice" Hello, Today I fitted the tanks together and placed them on the main spar. The leading edge of the tanks are not matching with the leading edges of the outboard leading edge assemblies. The fuel tank leading edge is approx., the skin thickness, or 1/32" higher than the other skin. Has anyone else had this problem? What is a solution?

It may seem like 1/32 of an inch, but would not be that much. Not a big deal John Oliveira ----- Original Message ----- From: "Michael T.
