I'm starting to get the Goliath design files place on Github .  This evening the files necessary for creating the propellers that rotate CCW were committed.  Please check them out and let me know if there's anything else that should be there.  The instructions need additional detail, but I've tried to label everything to be straight forward.  The G-code files are included, but aren't optimized.  The roughing pass is fairly efficient, but the finish passes waste some time going over areas that are already cut.  If anyone has the inclination and expertise to improve on them, please feel free.

I'll be adding information to the repository as the project continues so be sure to periodically check it out!
