Finsrud's Perpetuum Mobile

[ace569er]

Tho I posted this else where to  answer a question. I paste it here to because I think it appeals;


Though this is just an educated guess....I think the center pendulum is moved by the magnet that tilts the spring as well as the balls weight on the tilted wheel putting pressure on the spring(big one). Also the 3 pendulums are off set to the same side as the very large magnet, on them, is offset on. I think this helps push the center pendulum. If I arrange all repelling magnets in the position shown. Then stop it and just touch it it want to go in that pattern about 2-7 rotations. if you kick it with just one of the three off sets you can keep it going around. I think this is at least somewhat close to what makes the center pendulum move. Sadly everything relys on everything else to run, in my option. so it is hard to test, with a controlled pendulum to push it. yet alone the ball and spring factor. Unless it is completely  built. So I hope this model helps a working replication to be made. Because I want one!!!!!!!!

Here you are. Please fix anything you think is off and send it to me. I'll try to compile the ideas together. Hope enough people, do it. There is a few things I am not happy with, mainly the wire, pendulum tripper. I can't get the angles to match the distance...... So something is wrong. Also I don't see how the base is separated from the, track support, arms and attached the spring. So the track can tilt. Would love feed back from anyone who has seen it in person. The file is a compressed sketch up file, enjoy.

Thanks, nice work to see it three dimensionally....

Nice I like it it looks good.

Here is my finished, Finsrud's PMD 3-D replication.

Curious if anyone who downloaded it, modified or improved upon it? Please if so upload them, I am, very, interested in seeing them!
