I had the idea years ago to put a tool on top of my stationary planer. For a long time I just had a piece of plywood setting up there and then set my mortiser on top-worked ok but moved around a little. Finally got around to getting it clamped on. I 3D printed some brackets, 2 on each bar with one side just bolted on, the other remove with a knobs. This still allows me access to change blades( or in my case rotate the cutters which is hardly ever) Much more solid now. I had thought about using it for a miter saw or drum sander as these use same in/outfeed area, but settled on my mortiser for now. I never really used it for setting the boards up there, usually use a cart if I have more than a few. Thought maybe others would find it useful.
