Trying to attach a gear to a motor

Thanks for the reply. I should mention that I'm trying to go at a very low RPM actually. My motor here is 60RPM and I'm planning to gear this down as much as possible with gear ratios. I'm eventually going to be turning a large clock face and that obviously needs to turn really slowly. I would be fine with getting a different motor if necessary. I would like to keep the gears though since they are kind of key to the project for aesthetic reasons. Thanks!
