Chris's New Steering Engine
bent:
Catching up...wow, what a neat model. Glad to have been onboard for most of the build! :popcorn: :ThumbsUp: :cheers: :whoohoo:
steam guy willy:
Hi "C" ,Another lovely engine and it works a treat with the porting arrangement :ThumbsUp: :ThumbsUp: am i right in thinking that you turn the wheel clockwise to turn right and anticlockwise to go tother way ?!! just thinking about reversing the ship and using two engines for the props , this might be a silly question but it may confuse the landlubber engineers when connecting everything up ?!!
Cheers

Exactly, though this is a completely separate system from the props. It does not change based on which way one or more props are turning. For those who don't know, there are a lot of ships with two propellers, and by changing the speed and direction of them independantly they can help the ship turn, and sometimes spin in place. I have a radio controlled twin-screw tugboat model, each prop with its own motor and controller, and its easy to steer it with just the props, leaving the rudders in the middle. When stopped in the water, running one forward and the other in reverse, it will start to spin in place. Things get even more fun on modern ships with 'azipods', that actually turn the entire propeller around on a vertical axis, a lot of cruise ships with that setup can maneouver themselves in and out of the pier without a tugboat (many also have a thruster up near the bow). Fun stuff!

Diversion to an aside comment:
I was aware of the effect of multiple propellers and their use in turning (or trying not to turn) of a ship when I saw a picture of a torpedo as used in WWII with the two props coaxially mounted, and I assumed they rotated In opposite directions to provide a straight course to the target.
Have you built or considered building a watercraft with that feature? (And I can visualize it as two: One to swim and one to demonstrate the various interesting mechanisms involved)
On the steering engines: Is there an Elvin crewman who operates these when humans are not around? Perhaps his penchant for constantly causing the rudder to shift back and forth might have earned him the appellation "Flipper."

I have not built one with two props inline but counter-rotating, but another guy in our local club has done one like that, with a clever gearing system to drive the inner shaft one way, and an outer tube around it the other direction. Works quite well, and there were (still are?) torpedoes built that way for many years. It gives more thrust with a small diameter to still fit in the same torpedo tube.
