Sorry for the long delay in posting. I have been pretty busy at work and getting ready for Solidworks World 2007. Some of you have emailed for the Nucleus X sldprt files. I have uploaded them to http://www.mediafire.com/?4mtngxyydum (mediafire is a really cool service BTW).
I have to warn you that the modeling was really quick , and isn't particularly elegant. However it might give you ideas. Please feel free to modify and send me pics of what you do.
