Controlled Drop with Thruster?

[twharvey]

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,

What you describe should have been possible especially if you had a gyro attached. You are probably trying to avoid this but 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?

Thanks, mptak.

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