Hello: I am using a 3 inch stainless steel pulley to power a 24 foot cable around two bike rims. The motor is a 3/4hp garage door opener motor. The unit is a moving target assembly, the targets being paper only for pistol and rifle practice. The cable is 1/8th inch, stainless steel braided. I want to increase the speed of the targets from point A to Point B, approximately 9 feet. (The target will then reverse direction.) Is there a formula to use to increase the speed of the cable turning? I have a video I can send to show you the current speed, if you would like to see it. Thanks. |
