No, I was not trying to embarrass anyone, but to show that the cylinder chosen is not a good choice. A 2 in shaft has much better advantage if you have any potential bending forces. I had to calculate back-wards to find the shaft size, because it was not stated. I used trial and error. You could even use the same cylinder bore and change out the shaft and still have the same push force. The difference would show up in the return stroke. You might get by with that same cylinder for a while, but one day it will come into that big knot, and bend the shaft.
As an illustration your diagram is fine. It looks similar to this commercial model.
