How to Make a Three Axis CNC Machine

How to Make a Three Axis CNC Machine (Cheaply and Easily)
The idea behind this Instructable was to fulfill my desire for a desktop sized CNC machine. While it would have been nice to purchase an off the shelf unit the issue of price as well as size proved prohibitive. With this in mind I endeavored to design and build a three axis CNC machine with the following factors in mind:
-Use Simple tools (needs only a drill press, band saw, and hand tools) -Low Cost (this kind of got away from me however with everything bought off the shelf the cost for all parts is under $600 (significant savings could be made by skillfully sourcing some pieces)) -Small footprint (30" x 25" footprint) -Usable working envelope (10" X-axis, 14" Y-Axis, 4" Z-Axis) -Relativly fast cut rate (60" per minute) -Small part count (fewer than 30 unique parts) -Easy to source parts (all parts available from 4 sources (Home Depot + 3 online sources) -Ability to cut ply-wood (Succesful)
Lets get started... UPDATE: - Coming soon the ability to order pre-cut MDF pieces from oomlout............
