The multiple rollers of a coding machine are each embossed with the 26 letters and wrapped in order similar to an odometer.

Z A Y A B Z B C A

With the rollers displaying the message:
"FOUR IS A SQUARE",
each roller position is advanced by the value of successive digits of the irrational √2 to yield:
"GSVV KT D XWWDYH".
If the rollers are locked as one cylinder and rotated through the display window one may view 25 other encryptions.

Using a related but not identical process, and just the values of Π (= 3.141592), the following is the encrypted result:
"PAZYPMEPTUNYRXEWHFGNJRQMK".
Determine the original phrase.

Notes:
1. Spaces do not exist on the machine and are provided here (above example)for readability.
2. If it helps, each vowel occurs at least once.
3. [√2 = 1.41421356237]

(In reply to re(3): Hint by rod hines)

“Locking the wheels and rotating” is indeed the way to go.  The operation as performed in the ‘√2’ example is used on each wheel but with reference to the digits given for pi. 

What is the sum of those digits? Trust that helps.
