Adjustable "six shooter" Drill Guide

I saw a really cool drill guide on thingiverse that I was going to make, but then thought of a way to make it adjustable.  This is sort of a six shooter version of it, and when completed will have an adjustable fence that will ride a pair of dovetails on the sides.  I also plan to include a dust catcher which was also something I am borrowing.
Update, got bored after giving out half my paycheck today, finished up (hopefully) the design:

Actually after thinking about it, I am re-designing this again. 

And also, Merry Christmas!
