Creating a Mobile Table Saw Workstation Base

I’m starting to get more serious about building a workshop and from what I have seen, a table saw is central. However, when your workshop is also a garage, being able to move that saw around is key. In this video I document how I built a mobile base for my saw that used common materials and a simple design to get me started on a usable and expandable base for my workspace centerpiece.
I’m definitely an amatuer so I am sure I’m not doing things as well or efficient as possible, but I found I have to do to learn and improve. So hopefully this shows that even if you are just starting out too, just create. That goes for the video too!
