    2 images of my concept of a simple tiller operated Kitchen rudder have been posted in my gallery. If your not familiar with it, check out this thread.

    I would like to hear your opinions ( throw darts if you want :eek: ) and or suggestion for improvements. If I stick with this direction my next step is to refine it for ease of construction. Anyone who wants, is welcome to my Rhino file.

    Gary :D

    Here are the images:

    Gary,

    How many degrees do you have to raise the tiller to produce neutral and reverse flow? If its significant you might want to actuate it with a rotary actuator similar to an outboard throttle. The disadvantages would be more mechanical complexity and you would mess up the period appearance that the sculptured tiller gives.

    Just some thoughts,

    Doug

    I have been working on a few different versions. This one is an attempt to reduce it to the bare minimum. But thank you, the twist grip idea is one I haven’t considered. I will check the total travel at the end of the tiller. I’m working on some sequence shots to show how it operates.

    The tiller end travels about 18.5 inches to reach full reverse. Which is a lot but not that bad.

    Gary,

    It might be wise to be mindful of the torque required to move and hold the rudder blades in various positions. The original rudders used a worm, which could have exerted a lot of torque. It wouldn't have required any effort on the helmsman's part to hold it in position either. Unfortunately, it's hard to see how you'd get these numbers without a prototype.

    :D Sure would be glad to share. I have never built an operating version. I think some others have. I will dig out those files and pass them along.
