Folks,

I'm embarking on a project to build a modified copy of a DIY 3D printer.  See http://reprap.org/wiki/WebHome to get a rough idea.  In my case, I have my own lathe and milling machine, so I can fabricate more substantial components, e.g., by machining aluminum.  I also have larger stepper motors, some 3/8" precision rod and linear bearings that I can use.
