Wendell, again it goes back to that prototype kit

Cass wanted to use hard points in the wings instead of the standard root. He was going to cut off the rear of that front doubler and use 2 more adjusters there.

Now, what you have is an arrangement similar to the electric set ups. You just have a little extra doubler there LOL but that's not necessarily a bad thing at all.

Now about the question: yes and no. You want to open the hole up just enough to accept the bolt and not bind the wing if/when you adjust it. The best advice is to set it on the table at about .4 degrees positive and only open up just enough to pass the bolt without binding. I garauntee that if you do it that way, you will be in good shape and not have to open it any more. The more you remove in the hole the more prone you are to having some type of a failure over time.

So, just do it that way and call it a day. It doesn't take me more than a few passes with a round file and I'm done.
