Good morning VAF. A quick question I haven't been able to find an answer to through searching google and the forum. I'm finishing the right elevator on my empennage kit and when I try to thread in the rod end bearings for the hinge point, they are really tight after the first few threads. I tried the other nut plates in my bag and they are all this way. When I look at them, I can see the threads all the way through so it looks like they should be able to thread all he way through. It almost looks like the coating that on it is blocking the threads so I ran a tap through a couple. But I stopped because I am curious is this is the way it's supposed to be? Are they tight to hold a bolt like a nylock nut? or am I making a mess of things by running a tap through?
