I am just shooting too much to keep working that handle manually so I have decided to automate my Star sizer. I know some of the very creative and talented members here have done it and I am asking for guidance. I have watched the Youtube videos and want one. What I don't know is what motor, gearbox, etc I need to have it run properly. I don't have any of these components lying around so I would like to buy the right stuff the first time. Thanks in advance.
