The base is put together and here's a look at it. I'm using standard L-Brackets to join them together - 2 on each join so it should be sturdy enough. The thing I like most about this design is I'm not locked into this once I'm done - things are easily adjusted and tightened up - something I don't have with machine #1. (UPDATE - I am no longer using the L-brackets for holding the base frame together - I made my own brackets from angle aluminum, the one piece design is more solid...)

Base Frame Joining T-Slot

You can see in the bottom left corner of the first picture - Yup :) Machine #1 :) looks very small in comparison to the new machine - which, by the way, measures 57" X 36" so far.
