Most of my ancillary tooling is mounted to aluminum plates so they are portable and easily removable from the bench so that they can be stored elsewhere. They are held in place with clamps when in use.
Since I have a machine shop with lots of pieces of Aluminum laying around I can mount tools to plates that look nice. However you could do the same thing with pieces of plywood and accomplish the same thing for a fraction of the cost.
Please note; the Plastic Trash Bags covering the tools when not in use.
