What you're doing is expanding the hole slightly and smoothing it out. Press fit means that you have to push really hard on the gear to get it onto the shaft of the motor.
I have a mill and I am quite familiar with it. I've never used a reamer before, but if it is anything like a drill, then we should be good to go. thanks for the help.
