Just in case you all miss my posts let me clear up the gap.I haven,t been working on the model for a while now for two very good reasons.The client called and had me put her on hold as he has some remodeling going on at his residence and they wont be done till the early fall .That,s Reason one . Reason two . I didn,t think they would do surgery  for "Tennis Elbow" ! Yup , BOTH arms ! I am just now  getting well enough to start back in the shop . My doctor said that YES you can get "TENNIS ELBOW" bad enough for surgery just like carpal tunnel ! Hmm . Well anyway during my hiatus I discovered some things that will use on MY ARIZONA when I start it and one is real wood decks by yours truly . The PROP question was solved for me today . I just got finished a viewing a dvd on PEARL HARBOR-DEC.7, 1941.There were some very good shots of the OKLAHOMA upside down and especially from aft as the righting process began.TRACY,S right ! ALL four screws were the same size . They were of course left and right handed . Tracy knows as I do when you have more than one they have to be turning in different directions or the prop walk in close maneuvering would be murder , especially at very low speed in a tight harbor. Thanks for your vote of support .I will start working and posting on My client,s ARIZONA in about a month so keep watch . Thanks again .     tankerbuilder

Not aiming to argue with you Mr. White, but if you look at your picture of California, you will notice the port screws turn counter-clockwise, and the starboard screws turn clockwise (notice angle of blades). Pennsylvania class was this way.

Oh please, if I get something wrong, call me on it! In this case, you got me. I had originally typed it out the way you described, but came across that first photo and for whatever reason miss-interpreted the starboard props direction of rotation. I was a little surprised to see that, which is why I said "at least on that era" as I knew other ships were different.

I may be passionate, but I am passionate about the truth; if you can show me I'm wrong and help me learn I'm all for it.

This photo is of the Arizona at the time of her 1929 Modernization.  As you can see, the inboard props are three-bladed, and the port props turn counter-clockwise, with the starboard props turning clockwise.  And yes, the Trumpeter props are wrong, as are the brass ones from Gfactor.  The blades are much too wide on both examples, not in diameter(don't know if those are correct or not), but in the width of each individual blade.  You can clearly see it in this photo.

Tankerbuilder, I believe the four-bladed prop that you were referencing to Tracy White was actually a picture he had posted as an example of the different props used on the different classes of BBs.  I remember that picture, and I had asked him about it and it was from a later class of BB than the Arizona.  He just happened to post it in an Arizona thread because the current discussion at that time was about prop configurations.

It sounds like you are doing great on your model!  I sure wish we could see some pics tho'!  When you have finished, I am going to print all your posts as references.  You have discovered a lot of things to watch out for!  Thank you!

I say that because I forgot the number of posts already !

This is meant as a good-natured comment and not as a slam, but you do realize you can reply to past posts, keeping everything in the same thread so that future readers can find them all in one place, in order?

Second, while there were many ships in the US Navy that had different bladed screws to try and cancel or lessen vibration, the Pennsylvania class was not one of them. All four screws were three-bladed (and Trumpeters are all wrong). The screws turned counter-clock wise, at least on that era of battleship.
