Retire ha.

Retire? Whats that? I don't think there is anybody here who will ever be able to truly retire. Just take more breaks. LOL

I need a damn good engineer. I have the working model in sim, but the arrangement of interfering parts and interfering frames severely tests my limits. >.< Brick wall...where's my sledge? O.o

Does your sim work with only one set of weights (and balancing weight if you need)?

Silvertiger · Post by **Silvertiger** » Sat Aug 08, 2015 9:04 am

Of course. :)

Understand what makes the principle work. Reduce to simplest design. Build.

Believe it when I say there is nothing simpler; nothing more reduced. That's not the problem I'm having lol. Even though it's not Bessler's design, I understand what he meant that by showing it, it would be so simple and laughable that people may not think it to be worth anything. I showed it to a buddy of mine who summed it up..."REALLY? That's it?"

An extremely simple design yet you need a damn good engineer? Would a carpenters apprentice do? :)

Silvertiger · Post by **Silvertiger** » Sat Aug 08, 2015 1:12 pm

Nope, not in this case...an engineer. Even though the layout is simple, the interaction of the parts requires the engineering of two separate frames, yet intertwined. And that's for my standard design. However, I do have two backup work-around designs, also working in simulation, just in case; possibly a third that also works in sim. Only ONE of the backups uses one frame.

Flip you lever over and examine the effects from the other direction, then do side to side.

Interesting. Would you flip a car on its back and then try to drive it? lol :P Side to side doesn't matter, since it's driven by gravity. However, it's interesting to note that a 90 degree orientation works since gravity still has an effective influence, but it requires more parts and fine-tuning and a redesign of parts orientation, so why bother?

Could you explain what you mean by separate frames. Thanks

Best I can do. :)

One more thing. Did you build the simulation to an appropriate size and weight? Wm2d can have problems with huge or extremely heavy objects.

You have sparked my interest on this one. Let me guess: you are using a spring in place of the weight. The spring pulls your two frames together causing them to rotate.

Thanks Silver.
I am sure you are accounting for the weight of the mechanism itself and its position. It it balanced?
