Vans answer to my problem from yesterday was quite short : fill the hole with a rivet a,d build on.



The problem is that the hole is for a bolt and thus is to large for a rivet. So I decided to fabricate a doubler allowing the riveting and the use of a bolt. After a few tries, here is the result. Three rivets will hold the doubler to all the other parts, and one of the rivet will hold only two parts and the shophead will fill the hole so as not to interfere with the nutplate.



Here the backside with the nutpalte and the hole that will be filled by the shophead of one rivet.
