It is a different project. Like Harvey White I used a linear slide (linear stage) to move the drill motor, only mine only had about 1 to 1-1/2 inches of travel to work with. Other than a video camera or other magnification device that is the most expensive part. If you are not in a hurry you should be able to get one from eBay for 20 to 30 dollars. Look for Del-tron, Parker, Thompson, THK, IKO or something similar. I'm not sure the 2 rod CNC / Z axis assemblies from China have the accuracy and low friction you want and may require more room than necessary.

I guess I need to logon to the forum to find the photos section to check this out . I will definitely check it out though. Is this above and beyond the Instructable with more info or a different project?
Thanks
