Looks good lots better then my starter.
Solid ridgid tube would help the DC a lot. Lots of people use PVC but I like the 26 gauge metal. Goes together easy is light weight and easy to change.
If you search my posts you can see an easy mod to make the DC of the tablesaw a lot better and still keep the mobile base.
