I did several passed and was not very pleased with the results. It appears that every time I rotated the tube in the jig I did not get it back the right position for the next pass. The pic below shows the edges of each cut which did not line up properly.
I decided to remove the jig and use the guide alone. The guide was clamped to the edge of the table and while pulling the tube against the guide made several more cuts.
The results were better this time around. However, I does take some getting used to working with such a large peice. There were several cuts where my hands shook a bit moving off the guide and the following notch created by the router bit meant I needed to make a few more cuts all the way around.
