  • plans for building cnc

    We are not selling the plans at this moment. You can get the book authord by James Kelly and Patrick Hood-Daniel which is the same machines we sold plans for in the past. Here is the Amazon URL for the book: https://www.amazon.com/Build-Your-Machine-Technology-Action/dp/1430224894/ref=sr_1_4?ie=UTF8&qid=1483548108&sr=8-4&keywords=cnc+book Additional Information:

  • I would like some longer HIWIN rails and ballscrews for my x-axis, 9 feet or 108 inches. You list maximums as 78 inches.

    Yes, however, if you are needing a length of the HIWIN specification rail longer than our 78" max length, then you can abut more than one rail together to increase the length of the rail. We do this for our long X-Axis travels on our Fabricator pro machine.

  • How Do I buy linear rail 108" long

    We would need to order custom lengths of rail from our suppliers to fit this request. Currently our sizes are 55" for the linear guide rail.
