How to Build a Mini Air Hockey Table

This is a complex project. There are a number of small things that can go wrong with a build like this. The way air hockey tables work is that air is pressed up from the table. The puck floats on the air, thereby greatly reducing friction. That allows for the puck to move very quickly. One potential problem is that the puck will hit some of the wood parts hard. That can cause damage over time. So you need to cover those wood parts with some kind of protection. Also your air plumbing needs to be airtight.
