A couple days ago I was dimpling elevator skins with the C-frame.  My helper’s hand, pulling back the skin, slipped and it popped out of the male die as the mallet was coming down, creating a new dimple/hole about .20” from the existing hole.  I pounded it out with a hammer on a steel backrivet plate, but the hole from the dimple die is still there.  

   

I would consider this to be not too big a deal (I hope).  Perhaps a dab of tank sealant on the underside of the skin would be a good idea to prevent a vibration-crack from forming?  There must be SOP for this sort of thing?

He he ... I'll give you a cent to a dollar it won't be the last 

  I think I've got about 3 of those so far.  The general 

wisdom I've heard is to flatten it out and move on, its more of 

a cosmetic issue than a structural one ...

 I haven't gone this route, but unless the "new" dimple severely impacted the correct dimple, I would leave it dimpled.  It would make it much easier to fill with whatever body putty you use'  As for stress crack, I'd just clean up the edges of the new (dimpled)  hole.

I would have left it dimpled and inserted a rivet.   Let the painters cover up the mistake.  And, welcome to the club!

Well, I'm nearly done with the emp., and I have a QB kit, so there is

not much dimpling remaining! :-}

This is why I should check the list before I do anything. ;-}  I pounded it out immediately afterward without thinking it through completely… hey, it looked better.

Paul,  

   

I know exactly what you mean.  I did exactly the same on an elevator skin, and tried to weave the hole into a much bigger one for a huge rivet…  Consequently I created a rather large crack and had to get a new skin.  That said, I’m glad I did, as I know that every time I would have looked at that elevator I would have wished I hadn’t been such a fool.  Question is this, therefore;  is it on the upper or lower surface?  

   

Regards,  

Derek.

While building the rudder (RV-4) for the HRII we drilled an accidentally an  extra hole on one side beyond the end of the rib. Sooo we drilled a matching  hole on the other side too. Put rivets in both and when ask about the "extra"  rivets by other -4 builders we would respond: "You didn't the emergency AD  ?". Same guys ask how we got the 3 burner camp stove in the Rocket at OSH.  Answer was simple: We put it one of the wing tip lockers. You would be surprised  by the number of people what checked out the locker door size.  Do Not  Archive  KABONG 

 Don't stress out about a rivet, most real problems are caused by the loose  nut with his/her hand on the stick. (pun intended)
