you are an awesome and creative maker! I just stumbled upon your creations and am awed on many levels... reuse of scrap plywood whenever possible, sticking to basically one thickness of plywood for consistency and measurements, keeping the total number of machines small by using multiple configurations and resulting floor space minimized, etc. I continually see feedback concerning longevity/ robustness of your creations... personally, I don't believe these were created for large jobs, everyday use, etc.
