 Posted: Mon Feb 19, 2007 5:57 pm Post subject: "Half Deep" Rivets...? |
 |
|
Need some advice here.
There is not enough distance depth-wise across the narrow trailing edge of my flaps to allow for two rivets to fit butt-to-butt.
One rivet is to be installed from the top skin of the flap. The other rivet is to be installed from the bottom skin of the flap. The problem is that the holes (factory drilled) in the top skin line up perfectly with the holes on the bottom skin.
Installation of a rivet in either the top side or the bottom does not allow enough space for installation of the rivet on the opposite side.
Hence my question: is there such a thing as a "half deep" rivet?
Ideas...?

I assume you've test pulled a rivet in a piece of aluminum of the same thickness to determine what the final length will be.
Also, I believe A5's are called for but you could probably use a A4 which wouldn't be as long.

Great ideas. Thank you!
Here's what I did - hope it helps the next guy who reads this:
I installed A4 rivets on the line at the trailing edge of the flap. Did the ones on the top skin first to present a better "fit & finish", and then set the bottom ones in place "crooked". The A4's are slightly shorter than the A5's, and where there simply was not enough room for A5's, there was enough room for A4's if the A4's were slanted over to one side in the larger A5 holes.
As the rivet gun pulled the A4's, they straightened out as their length decreased, and they ended up flush.

a 3 or 4 mm offset will do it.

I understand your problem is fixed Patrick. When I hit that problem I ordered a small quantity of shorter rivets from assco. There is a short one and an even shorter one. I don't recall exactly but I think they were Cherry rivets. A bit harder to pull than avex but whats the diff? I built from plans though so i only had a few rivets that lined up.....Geoff
