Time to trim the hole in the skin some

The pipe has welds that you have to allow for when getting the step flange to fit snuggly against the skin. So I painted up the edge around the hole with a sharpie so I could use a round-edge file to start removing some of the material around the hole. Then as I started filing the skin and the pipe began to move inside the hole farther, I noticed that I had to back and remove more off the end of the pipe so the step could go in and not press on the inner rib. The painted line on the skin let's you keep track of where you've removed metal.
