rivet not flush around radius of elevator leading edge

Post by stevewiz »

Hi everyone, well we are coming to the end of the empennage and are rolling the leading edge of the elevator. Fought with it for a long time and got it riveted with no gaps in the skins between the rivets. The problem is that the rivets are not very flush going around the radius. I did edge roll and that could be part of my problem as the holes are very close to the bend line.
My thoughts at this time is to drill the rivets out and use my squeezer with 2 flats in it at each hole to flatten the area and re-rivet it together and see if I can get the whole head of the rivet to sit flush.
Any input appreciated. Also after careful thought we decided to and completed the SB 14-02-05 on all 4 locations since the leading edges were not rolled yet and were a little more accessible.

It would help if you can provide a few pictures, but my initial reaction is to say that I would probably leave it as it is and not drill them out.

If you do decide to drill them out... pop rivets can rotate during drilling. There is a serrated pop-rivet removal tool that will allow you to drill the correct depth and prevent rivet rotation available from Aircraft Spruce. (http://www.aircraftspruce.com/catalog/t ... -03368.php)

I don't own the tool myself, but I do own its sister (http://www.aircraftspruce.com/catalog/t ... emoval.php) for regular rivets and that tool has been absolutely invaluable.

Cheers,

Steve,

I don't think I would worry about it if I were you! When the elevators get installed on the horizontal stabilizer, nobody will ever see the rivets. I would say to build on! Perhaps try another method on the other elevator and compare the results. No reason to drill anything out now - you might do more harm than good!

If you post a picture, we can give you a better opinion....

Looking at the picture, I say leave it and build on.

If it bothers you when you are done the plane, you can fix it then!

If I remember correctly, I thought I read somewhere that you could lightly tap the outside edges of those rivets to get them to better form to the skin. I thought Vans had that in the instructions but my memory is not what it use to be? Hard to tell from the picture but if they are against the skin in the center that may possibly work?
