    I would like to build something similar to the photo. Building is not that much of a problem. Only problem I have is: no clue how to calculate how much torque the motor has to have. Respectively what kind of pitch/diameter the ballscrew has to have or what gearing I should use. Can someone explain how to calculate that? I already have some motors ... these where made for actuators but I have no idea what specs they have ...

    In the afternoon a friend of mine is visiting an he can probably tell me the specs.

    Hello,
    before designing and building the actuator you need to know how much torque you need to move your SIM. When you have calculated the necessary torque, you can size the motor, the reduction ratio and consequently the screw step.

    Good luck for your job
