This is what I put together as my 36"x12" grid plate for my small VMC. I'm on a tight budget, and just getting started in CNC. I figured this would be a good project to run the machine on, and help me out with set up time later down the road. The through holes will be 1/2" for the locator dowels, and the blind holes are 1/2x13 thread. Any input would be appreciated, as I'd rather change the design now as opposed to later. The plate will be made from 1" mild steel.
