    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


    If Leonardo Da Vinci were alive today, he would be humbled by this design. This is a beautiful design. I was up until 7:00 this morning building on this thing and am very eager to get it done.. Great work..

    you asked for it.. I had problems making the counterweight work. I think my problem is that I used the wrong sized rubber band. I found the same kind of band that you used on yours and haven't put it on yet..

    Your welcome... and I meant every word I typed... I just finished this lift yesterday. I spent about 10 hours building it. most of that time was on the motor, gear head. This is because my fingers are old and fat.. lol.. This is going into my next machine that is going to wrap around my office.. I'll send you a pic tomorrow... Thanks for a great build

    omg, i just finally realised how it works. The gear don't change direction the chain move height. stupid me. Iv'e been stuck on it for weeks.

    Yeah, there are some problems thought if you don't look at the instructions really carefully though. A preview will be put up soon
