HobbyCNC DIY CNC Router Plans are very thorough, 96 pages total, 49 pages of detailed drawings. includes complete bill-of-materials.  Lots of dimensioned drawings, illustrations and photos.

There is one part (the axis drive screw) that is made from common hardware-store components, but it does require welding. I have been reminded several times that a welder is a not-so-common tool, so I made up some Axis Drive Nut & Antibacklash Kits so you can avoid welding.

The plans are provided as a digital (PDF) download. Plans Current Revision: 03. If you want to see all the plans not including the measured drawings, feel free to download a PDF here: DIY-CNC-Router-Plans-HobbyCNC no drawings.
