I was amazed that it all seems straight and without a twist. That was all pretty fun. What's not fun is the next step...taking it all apart and cleaning out all the burr holes created by drilling and then doing the 3 step corroision proofing process. Notice the colored tags that I have put on each of the ribs. After you have taken it all apart and primed the pieces...you have to put it all back together again exactly the same way it was when you drilled it.
