We've got a table!

So after a lot of work I finally have a working table for the Z axis.  I decided to take 4 square blocks of aluminum and drill 3 holes in each.  Two for mounting the table and one that I would tap with 5/16" threads for the drive rods.  I made the table itself out of 1/4" MDF that I found.  I would have liked to have made it a little thicker, but once again I already had this and I plan to add a second layer on top so that I don't end up destroying the MDF from extruding.  Hopefully the combination of these two will be reinforced enough to keep from warping.  I also added all of the bolts into the sheet metal braces to help keep the corners square in addition to a single cross brace on the bottom of the machine.  The resulting structure, at least for the bottom is extremely rigid and I foresee no problems with it flexing during operation.  I put a 2 liter coke bottle in the picture for size reference.
