Rudders,
Again there is nothing commercially available, so for the tubes I used the same size stainless tubes as the prop shafts.
Brass bushes were turned up on the lathe and held together with Loctite.
The rudders are made out stainless sheet and some more of the 3/16″ shaft silver soldered together.
After a lot of shaping, cleaning and polishing they look like this.
