Hi ,
I finished this project recently and thought I would post some pics for those who maybe considering something similar.
I converted a 1973 Schwinn World Voyageur frame to accept a Nexus 8 speed hub. I am going to use this as my winter commuter as I had 700cc wheels built and got a pair of Nokian 106's for post November riding. Also I hope that this build serves as inspiration for others to try thier own repairs etc. A year ago I knew very little about bike repair. With the help of people on this forum, Sheldon Brown (a man amongst men!!) and the park big blue book of bike repair, I did the entire build myself except for the wheels which my lbs did for me.

Let me know your thoughts. The trailer bike attached is my son's. I picked him up from school on the maiden voyage. So far with about 100 miles on it I am loving the bike.
