Instructables
video CNC Gantry Using Drawer Slides
I have wanted to build a CNC machine for years.  I've finally gotten around to it but am keeping the cost and complexity as low as possible.  While using drawer slides is not the best method I wanted to play around with them and see how they would work.  

I've built the first part of this project using plywood from a local hardware store and the drawer slides from Lowes.  The drawer slides that I used were 18".  I will probably move up to 28" slides; they are around $20 a pair and will give a longer run.

This is just the first video of this project.

Thanks for taking a look.

To address the play in the sliders, I wonder if using the external part (or shell) of a second slider would work. In other words, you would have 2 sliders side-by-side, but only one of the traveling arm assembly, gliding back and forth from one to the other.
Great instructable! Will be tackling this at some point!

Andsetinn - Thank you for your comments. I should transfer or redo some of these video Instructables into regular picture and text entries - I do agree that the regular old format is a nice way to see what folks have built.

This drawer slide project has been a lot of fun. It was really cool to see it completed and work with the small rotary tool. My biggest problem with the rotary tool was the lack of a bearing and inconsistent results. The slides actually seemed to be okay for the time being. I've redesigned the gantry to hold a full power router with a regular 1/4" bit. I hope to have the revised build done in the next few weeks. I'll post a follow up to show it.
Thanks again for taking a look.

Nice build, though I prefer the "old style" pictures and text instructables. :)
I've tried these exact slides on a vacuum machine and didn't like the results, too much flex. I ended up binning them and going to roller skate bearings on a heavy duty metal pipe, which was a different type of headache. Your gantry will be heavy with both Y and Z axis on it.
