It's a simple Rack & Pinion assembly with a tripod mount on the bottom and a camera mount on the pinion, and possibly a second rail for stability and a method of locking the position of the camera.

You've got me thinking. The camera bellows' that were popular years ago, contain many of the components that a macro focusing rail has. You may be able to get ahold of an old bellows and make some simple modifications to it. That might be easier than starting from scratch.

Especially if you don't have access to a Bridgeport.

This is by far the easiest and cheapest way. I did the exact same thing about 45 years ago when I didn't have two pennies to rub together, but did have a rarely used drillpress vice and a few workshop tools. Now I see someone has shown the same setup for a DIY project and I know from personal experience it works well (although "heavily"); at least it will provide you an idea!
