some thoughts on rudder shape
I have been working on how to construct my rudders. I have drawing which gives basic dimensions enough to form a good profile. (see attached)
From this web site http://www.history.navy.mil/photos/...h-f/dd842-c.htm I found 2 photos NH 102957 & 958 which show the rudders and propeller in dry dock from a similar ship USS Fiske DD-842. Now I know the rudders have a air foil type cross section to them but no dimensions to go by. I can only judge the shape by the appearance in the photographs. Any thoughts on how to model these? Is this a "best guess" situation? thanks Don

Re: some thoughts on rudder shape
hello
hope this picture will help you to draw your rudder, it's from a French destroyer built in the fifties under a US blue print after WW II. Ithink it's very close to the one you are working on. Philippe

Re: some thoughts on rudder shape
Thanks for the link. Tonight after I got home from work I made one rudder based on the dimensions from the drawings of the ship. I thought it came out pretty good.
The stock I used was 1/8" thick basswood. I would like the hinge the two pieces together but I am afraid of spliting them.

Here's a rudder photo from a Clemson class US flush deck destroyer, the USS Farragut, DD300....

Re: some thoughts on rudder shape
Hey.. thats pretty cool!. Almost a sharp edge on the end. The Zellars is an Allan Sumner class destroyer with twin screws and twin rudders.
I tried drilling a 1/16" diameter hole thru the 1/8" stock and found the wall to be a might thin exspecially after a little shaping. So I did some tinkering around and decided I need to go up in thickness about .03" with the stock. Drill my hole first which will allow me to put a small pin or nail to use as a hinge then do the final shaping. I found this photo as well of the Sumner in dry dock.
