I got tired of storing my table saw blades and accessories in various places all around the shop so I decided (finally) to build some storage to go under the table extension. One thing that helped set me on that path was replacing my old broken Delta mobile base with a new Bora Portamate model that had an extension for the outer pair of legs.
The before picture (note - it usually isn't empty under there but I cleaned out all the junk to make room for the storage unit):

The open shelf at the top is for miscellaneous stuff that I grab for all the time, like push sticks. The trays on the right hold all my saw blades (wow - didn't realize I had that many). The small drawer below the blade trays is for my dado set which comes in its own box. The other drawers are for everything else that's TS-related. Just finished it this afternoon so I haven't loaded it up yet.

One more note. I had to leave a 6" gap between the right side of the saw cabinet and the left side of my new unit as that is where the tilt wheel of the saw is. Likely I will find something to store in that space too.
