Greetings:

     

    While back drilling the bottom rear skin to the ribs on my right wing, I managed to drill a hole through the rib flange in the wrong location.  I know that nobody on this list would make such a silly mistake, but imagine for a moment if you did.  Would you leave it as an empty hole under the skin or fill it with a flush rivet.  I suspect that the best solution is to put the extra rivet through the skin, but it falls crazy far from the normal rivet line and Iâ€™m vain.  

 

  

 

    Thanks for your help.

Put a rivet in the errant hole and put in one or  two more rivets around that site to satify the strength requirements of the  area. If anyone notices one extra rivet, on the bottom of your  wing, no less, you should run that guy out from under your airplane. I  mean, what the hell is he doing under there in the first place?

I won't openly admit to any errant holes in the underside of my wing, but I intend to be very diligent not to let a guy like Dred describes below, anywhere near it.

Bill,

If the hole is only in the rib flange below the skin, and it's nowhere 

near the place it should have been, leave it be.  You'll not need to 

worry about

it for the sake of strength.  It's a round hole after all and not 

inclined to crack from there, being on the bottom.  If you did the skin 

too, then put

a rivet there and forget it. It won't be seen when the plane is 

assembled anyway.

Larry:

 

 Thanks for your reply to my rib flange problem.  I visited your site.  Lots of interesting things.  I'm a bike builder also.  I have made several long wheel base recumbents and a few bikes that come apart for transport in small airplanes.  Your short wheel base design looks great but I have a question:  Do you have enough clearance between the front wheel and the pedals to allow you to pedal while turning?   Thanks again for your help.

Hi Bill,

Yes, the clearance is more than adequate to turn without running heels 

into the tire.
