I bought this to turn a wooden rectangle that is 14 inches by 4 inches. Pololu - Power HD High-Torque Servo 1501MG
It has the power to move it with some to spare. When the motor is not moving it is wobbly on the plastic horn to the servo's metal gear.
I don't know what to do. I was thinking of using this since I already have one. Pololu - 131:1 Metal Gearmotor 37Dx57L mm 12V (Spur Pinion)
I know it has more power the servo and it is very sturdy, but there is no position control and I don't know how to put a potentiometer on it.

Can you give more detail about the problem? When you say 'wobbly' do you mean the servo is jittering (moving backwards and forwards a small distance), or that there is play/backlash in the connection to your mechanism, or that the mechanism is mounted directly on the servo and is causing it to flex in some way?
Servos are not designed to support heavy loads. How are the servo and load connected?
"that there is play/backlash in the connection to your mechanism" that seems to be the best description. The load is directly attached to the servo.
The load is directly attached to the servo.
You may need to support the load on a platform like below and just use the servo to do the rotating.

One way to take out backlash is to apply a small preload. If we could visualise your system, it may be possible to come up with better suggestions.

to support the servo. I am having trouble aligning it. When I screw the top in and rotate it the bottom holes move forward and back as it rotates.
What can I do to fix this?
We need pictures of your setup to make any suggestions......

You need to better explain your servo and lazy susan setup. I would think the lazy susan would be supporting the load instead of the servo. I would expect the lazy susan to be mounted above the servo supporting the load, with the servo underneath only turning the bottom of the load without supporting the load. A coupling would be used between the load bottom and the servo horn to rotate the load.
