Rotate, crop and extract from image

[Thekid]

Hi, I have an image similar to a clock, with numbers and letters going around in a circle. I need to extract the numbers and letters from the image and have them print out in a straight line and in order from inner circle working out. Here is an example of the image:

Since the characters in the image will be different each time I am starting with a screenshot, then I think I should probably crop at the "12 O'clock" position and extract those figures, then rotate the image about 10 degrees and do the same thing, etc until the image has rotated 360 degrees and I have all of the characters.
I did try a portion of this by cropping the top 2 chars in paint and saving the image and:

import Image
from pytesser import *
 
image = Image.open("image.jpg")
print image_to_string(image)
 
 

That worked great but I need to rotate as well. The following code doesn't work right but it has some aspects I need:

import Image
import ImageGrab
from pytesser import *
 
 # take screenshot 
image = ImageGrab.grab()
 #haven't found the exact coordinates yet for box, just an example
box = (100,100,400,400) :
im = image.crop(box)
# rotate image 10 degrees
im1 = im.rotate(10)
 
 

Well, you can see I don't know what to do from there, or how to keep cropping and rotating, I know I need a loop, just not sure how to implement it.

I should also mention that the crop is an up and down rectangle so I can capture 2 chars at once similar to this:
