I would like to make a slab flattening table with metal legs, similar to the picture of the CNC machine I have posted. I would want the Y axis to be 2500mm long, and the X axis to be 1500 mm long. I think the C-Beam linear rail will be good for the main four sides. In the middle, I think 20x80mm V-Slot Linear Rails running between the two long rails (in the X direction) would be the best support to lay slabs on. I would need 3 20x80mm v-rails to provide support roughly every 2 feet. I am open to suggestions on the legs, but currently am thinking 40x40mm simply because they are square. For the movable X-Axis, I would like two more C-Beams placed in parallel. My router would go between the two rails, and I could hopefully plunge the router low enough (Z-Directions) to reach the slab without shimming it up. I am really needing help with all the small accessories which would attach rails the rails and legs together. I obviously need a sturdy design that is flat and rigid. I have looking around this forum for anything close, and only found one thread about slab flattening. I would like my table to be build purely from OpenBuilds parts... No wood. Too bad I'm a complete idiot when it comes to google sketch up. Can anyone design what I need? Thanks!
