I'm sorry that Van named 2 little 4" x 12" triangles 'forward canopy decks'. These are the pieces that rivet to the top of the top longerons from about 2" aft of the instrument panel, where they are only an inch wide, up to the 'sub panel' where they are about 4 " wide. I have no intention of riveting the upper structure & forward skin yet. But, clecos holding these F-721A's on the longerons interfere with fitting the canopy frame. I'm trying to determine whether I'm supposed to go ahead with riveting these 2 small pieces so I can fit the canopy, & not interfere with anything else in the process.

I think mine were rivetted to the longerons in the QB kit but I left clecos in on the sub panel until I was sure it wasn't coming out again. Pretty much this means you have to have all the structure that is going to support your radios complete.

Nelson" Subject: Re: RV7-List: -7 tipup F-721A: When?? Hi Charlie, I'm at this point (building/installing the canopy frame) so I can't accurately say "go for it". In my case, I riveted the forward canopy decks several weeks ago only to realize that I needed to attach the tabs that in turn attach to the instrument panel. It was not very difficult to fit and rivet those tabs into place. The inboard tabs were reachable w/ a pneumatic squeezer and a longeron yoke; the top tabs were reachable with an "L" shaped bucking bar. I think that the only other item that could cause some heartburn is the possibility of adding a dimmer for a map light or something similar. Some suggestions: - Can you cleco from underneath (even if for just a few holes)? Not sure if the clecos will stand a little too tall. - Maybe rivet using 2 or 3 rivets. That way if you need to remove it, drilling out 2 or 3 rivets is a much easier exercise. Here's hoping I don't run into any problems! ;) Good luck, /\/elson RV-7A "tip-up" Austin, TX ~~ Lately my memory seems to be like a steel trap .... without any spring. ~~ On Tue, 17 Jun 2008, Charlie England wrote: > > Charlie England wrote: >> >> Those who have gone before, >> >> When is it ok to rivet the F-721A's ('forward canopy deck', @ instrument >> panel) to the longerons?

Frank mentioned that they come riveted in the QB, so that probably means it's safe to go ahead with riveting. Cleco from below might work; I also like the idea of just riveting a couple of holes. I hadn't thought of that. That would give the 'best of both worlds'. Thanks! Charlie David E.
