DIY makeshift router table - sliding dovetails

I'm working on a project to build a Shaker Dresser and the plans call for all the drawer dividers (front and back) as well as well as a divider to create 2 drawers at the top level to be sliding dovetails.
I tried to do these by hand but they were quite a challenge so I decided to go the router route and build a simple DIY makeshift router table for this purpose.
