Just need to know what length to get for the X2, XYZ also is this something that a beginner can do. CDCO machinery has them for cheap, thank you for your time.

You'd need the 6 inch scale for the Y axis and the 12 inch scales for the X and Z.
They have an 8 inch scale that works with their DRO #30011 but the X and Z have a little more travel than 8 inches.
You can see how I mounted mine here (http://www.hossmachine.info/projects.html#DRO) using something similar.

Thanks Hoss.
