How to Create external pipe threads in solidworks 2006 tia sal

Greets All

I was wondering if any one can point me to a tutorial or an example file on how to create external Threads on pipes.

I'm trying to design a very cheap Hoffman Appartus anyone can build using clear pvc pipe and rubber stoppers. I've created a draft image of what I want the parts to look like. An example Image can be found here.

PS A Hoffman Apparatus is for doing electrolysis testing (splitting water)
