Here’s a design for a folding stand that I made for my power miter box. I started with a couple of 2x boards that I draped across a pair of sawhorses (see drawing). I centered the saw on the boards and drilled holes for bolts that anchor the saw to the bench. Then I cut a pair of 4x4s to the right length for crossbars and ripped them to a thickness 1/16 in. shy of the height of the miter-saw table. I also tapered their ends so that in the folded position the crossbars remain flush with the boards.
I had some blind pivot hinges left over from a job, so I used them to attach the crossbars to the boards. But a countersunk machine screw or a lag bolt would work just as well.
