In the old days it was with a hammer and a jig. Now it involves something similar but I believe there is more jig and hydraulics and less hammering.

Obviously from my response, I've never worked at a prop shop, but one thing that might be relevant information is that for a well made prop in good condition one can usually have 3 inches of pitch added or subtracted. Trying to add or subtract more will depend on a lot of factors and may or may not be able to be done.

I had my 12" prop changed to a 9" and now it's in the shop again to be changed to a 10". (turns out the perfect sweet spot is probably 9.6" but I want 10").

If you want to change your 22" pitch prop to a 9" you'll be out of luck.
