For the DIY machine builder creating a straight flat surface on long steel tubes has always been difficult. This machine uses two suspended wires to create a flat and co-planar plane that is used to optically align a cutter to the work-piece. within a few microns.If you Google DIY Laser levelling using-webcam and laser level You will find a discussion on optical alignment. Note that towards the end of the discussion the findings indicated alignment using wire or nylon line and a USB microscope produces the best accuracy. I will update the files as the work progresses.The DWG files will work with Autocad 2017 or above. Unzip the files into a folder then open the _Main file first.
