Would love some feedback and thoughts on a mobile base I am building. I am adding an extension and Bench Dog Router Extension to the saw. Being in SoCal, I like to do a lot of my work in my driveway where there is more room, but due to some rough transitions, I needed a base with a bit more ground clearance. I have 4 total-locking 5x2 casters and am using 1x3 16ga steel for the main frame. The cabinet will be independent of the table saw. I was planning to use two uprights to support the long extension but am not sure about the best way to go about this. I am concerned with flexing of the rolling base and the impact on the table flexing out of level. Here is a link to the online Imagur album with more photos. https://imgur.com/a/eirmc
