so why not use something like this http://www.youtube.com/watch?v=ohap0KAo7kE ? And modify it with springs. You would just need to use modifiable tension on the springs.

I have my suspicions about this video.  I have seen it before and there is something about the rotational movement that bothers me.  It does not appear linear and fluid which I would expect if all components are somewhat matched.  Of course, it stopped after a little bit, which does not bother me at all.  IF this were real, the stopage could be overcome utilizing better construction methods and materials.  I just don't think this is for real.  Anyone else's opinion?

Excellent!!!

In it's current form it would have a problem lifting a weight.


When I have attached the elastic, I will find out how much weight my machine will lift. It has 3 @ 1 Kg weights powering it with 3 @ 30 square waves.

I have a cast Celtic skull I got at Wookey Hole in Sommerset, I'll start trying to hoist that.

Best of luck to you.
