Sluggo and All,
Several (many) years ago I designed a simple tool to align the turbine to the tailpipe. This was documented the JPO newsletter,
CONTRAILS, Volume 18, Issue 1 /Winter 2006, pages 9-10.The article is entitled "Turbine Alignment Tool". Fortunately, this issue is available on the JPOwebsite,
www.jetpilots.org. Scroll to: CONTRAILS and open the Winter 2006 issue forthe article, found at the 2nd year up from the bottom and on the left.
While you're at the site check out some of the other issues for valuable jet tech hints and consider joining JPO, an application is located within.
