          Octuras soak for 3 hours ABC is about 1 hour to cut them down I have a digital readout cutter I use for the most part annealing is not needed unless I am changing the pitch

            Thank you, as it seems you are doing it right. In the future would it be of interest to you if I were to ship some props for you to harden? As I do not have the right oven, bath for this heat range, time. And I very much agree with heat treating is not always needed. It would only be for those I have changed pitch/rake. I would assume to pay for your effort and time.

                  Pitch is how much the prop will move forward, rake is the slant of the blades. A lot of people just say pitch. I more so twist the blade while bending so it's not technically changing the rake as I'm not removing the blade from hub. Sorry about that terminology, either way the blades are bent/moved from their original castings and I like to run high rpm so re-hardening is beneficial.
