i am also building this lift totally awesome concept. i have one question in theory you could go as tall as you wanted (i was thinking 3times as high as you have here) as long as the base and the top remain the same is that a safe assumption or would there be some technical difficulties. I am wanting to use the elevator as one of my main lifts for a ball machine i think it would be an awesome feature we will have to see if it works
