This miter station is only half built, but it is already proving to be quite useful. My favorite feature is this folding, self-locking, leg design.
With two hinged joints and no other hardware, the leg is a floppy noodle until you deploy it. Then it becomes very rigid and strong. The stability and strength of the leg is quite surprising. Once it is deployed, you can even knock the leg in the side and it will stay rigid. A key to this stability is the way the hip box pivots from an inside hinge while supporting the top outside the hinge. This creates forces that prevent the leg from folding unless you lift the table and the leg off the ground far enough for the hip box to pivot down.
Not shown in these pictures are the fences, dog holes, flip stops, further extension tables that slidably mount to the folding wings when deployed up, and in-progress folding dust control system. The sliding extension tables use ½ inch emt rails and offer up to 9 MORE feet (as shown, the saw has 70 inches of support to either side of the blade) of support right or left when needed. I tend to use 3-foot emt mostly for these, which allows stops out to 100 inches from the blade as needed.
This station is based on the design in ShopNotes No. 31 with a few changes. The main cabinet is taller and wider. The shelves are torsion boxes for strength due to the extra width. One problem with the original design is that the saw is not very useable when the wings are folded down. I added mini-wings that are always deployed so the saw is useable all the time. The mini wings provide 31 inches of support to each side of the blade. With the far end of the folding tables being so far out from the main cabinet, I also needed a better support strategy out at the ends so the saw station won’t tip side to side under load. The folding legs do this job well. I also added the sliding auxiliary tables.
