CNC Drawer Slide Build - a Different Approach

I've tried lots of CNC gantry designs using a variety of drawer slides with not great results.  I didn't want my work space to be moving so a lot of time was spent trying to design a stationary deck.  This design seems to work pretty well.  This is still a work in progress though.  The next steps are to install the NEMA motors and then start working with the computer connections and G-Code.

Thanks for taking a look.  I'm also always grateful for comments and suggestions.
