This is the final assembly that hold both the Y and Z-Axis assemblies. By now, the concept is pretty familiar.
The positioning of the Y-Axis rail is 1.5" in from the back and the height depends on the type of router you are using. For a little router, like a Dremel or a laminate trimmer, the Y-Axis rail will move closer to the table top, for a larger router (I used an old Craftsman router I inherited from my dad), the rail will move farther away.
Here's all three axis' together for a test fit (again, still with wood screws). This is where you begin to see the project really start to come together. Still no motors or electronics, but pretty cool nonetheless.
