Don'y forget to watch Part 2 where we solve the problem encountered here.
This is my attempt at making a Vacuum Table for my CNC machine

I finally have gotten around to making a vacuum table for my machine. I was planning to make one the fill size of my tabletop but decided it was a bit ambitious for a first attempt. How right I was.

The idea for this build was built on one simple idea. Large holes for the pods fed by tiny holes such that even if many of the holes are uncovered the vacuum cleaner that I plan to use fore this projecj will still be able to keep the vacuum up to the rest of the pods. This is the mistake made in many designs that I have seen. They use large holes which as soon as they are uncovered, the vacuum source can't keep up with the air pooring in through the holes and the rest of the pods loose their vacuum as well.

By keeping the holes small the effect of uncovering these holes is minimal and the rest of the pods should keep their vacuum. The price to pay for this it the increased time to pull a vacuum on the individual pods but this is very minimal.
