Here's the latest example.

I make some clocks that are just packed with gears. The trick is to make one tooth a component and the use the SP context menu to define it as "convexhull". Next use the rotate tool in SU to copy the tooth as many times as necessary for your gear.

Thanks, mptak.

I've got it working! In case anybody else needs to do it, here's the model of the weight falling.

functions from the sketchy physics library like teleport or setVelocity would probably work.

Thanks, mptak, those sound like just what I need, but where can I find this SketchyPhysics Library?

I building a clock model where the diving force in the real clock is a weight that drops puling a string that in turn unwraps from a drum, thus driving the clock mechanism. To make the simulation, I'm using a motor on the drum to drive the clock. I would like to have the weight drop at a controlled rate that would mimic the action of the real thing. I tried using a thruster on the weight with a negative number in the strength box thinking to adjust the strength number to set the rate of decent, but it just drops as if it were a group with no connection, when the simulation is run.

Does anybody know how to make an object drop at a designated speed?

Any ideas would be appreciated,

Here'a another clock simulation that works (mostly): https://www.youtube.com/watch?v=OlwAsxMtGno

I couldn't upload the model because the file is too big, but I did put it in the 3DWH and made a video of the problem.

Hi All,

I'm building a clock originally designed as a wooden device by Brian Law (http://www.woodenclocks.co.uk/). The clock is driven by a motor on the gear on the lower left looking at the front of the clock. In the original design, this was a round box with a spring drive. The clock is regulated by a pendulum that operates the escapement, which , in turn, regulates the clock's rotation rate.

The thing is working pretty well right now, but there is one small problem. The pendulum's movement is controlled by an oscillator. By changing the oscillation rate, it should be possible to set the rate of movement of the whole thing so that it actually tells the time. The trouble is that the pendulum wobbles about it's pivot point (see arrow in screen shot.) This, in turn, causes the escapement to behave in a erratic way as well. My question: is there a way to anchor the pendulum's pivot more securely?

Any help would be appreciated,
Tom

Thanks, John,

I'm in the middle of building a model of a pendulum clock in SU8. I do have SU7 on my machine, but if I use it, I'd have to start over from scratch. I'll try turning off all the other plugins and see if that works. All these crashes are getting to be a bore.

A cool trick is use SketchyPhysics "alone" inside the Plugin folder !
So just make a special "Plugin" folder for iself!

So no incompatibilities with other plugins!

Hi Pilou,

How do you do this? Can SU have more than one Plugin file at the same time or do you give it a different name?

Thanks,
Tom
