Mobile Base / Storage Cart for Contractor Table Saw

I have a Delta contractor type table saw.  I added a plate to the bottom to catch dust and chips years ago, but now it's time to build a proper cabinet for it.  I got four locking casters from Woodcraft, and a sheet of 3/4" cabinet plywood from Home Depot.  A couple hours with a circular saw and table saw, and I've got a box to set the saw on, with storage and dust collection underneath.

I've been using it for a while now, and I really like the dust collection.  I installed a piece of melamine-faced particleboard directly under the saw.  It slopes down toward the back of the cabinet, where there's a 5" wide cavity for the chips to drop into.  In that cabinet is another piece of melamine-faced hardboard, sloping toward one side, where a piece of 4" ABS plumbing pipe connects to my dust collector hose.  You can see the configuration of these dust-directing ramps in the photo below.  I also packed foam scraps from an old mattress pad up under the cast iron top, to limit air leakage.

to the port at the lower right side of the cabinet.

The rest of the cabinet is pretty much just a plywood box.  I put locking casters under each corner, and they work fine to hold the saw steady, at least for the way I use it.  They lock the wheel and prevent rotation of the caster assembly with one foot press.  I rarely load up big pieces of sheet goods or timbers on the table saw.  It's more for precision cuts on mid-size workpieces in my shop, so I don't need it to be totally immobilized.

I still need to fit the storage, but here's the saw mounted and usable,
with the old stock steel legs sitting on top.
