    Ship or boat? Direct control or pilot following? There are a lot of ways to implement hydraulic steering.

    A short tiller is used, as shown. There should also be a means of attaching an emergency (longer) tiller in case the hydraulic system fails. What don't you understand?

    The mechanism has been clearly described. What specifically do you not understand? You already have a "tiller detail drawing". Describe exactly what you don't understand. For example, say "How does the tiller attach to the rudder, or, "How do you figure out the mechanical advantage required?", etc..

    The tiller attachments function is to attach the tiller to the rudder.

    I hope you can find someone patient enough to help you but I don't have any idea what you are trying to do. Obviously, the function of each part is shown in the drawing above. You can SEE what is attached to what and why. What you see is the function---- how turning the steering wheel one way or the other will force fluid through either the right or left hydraulic line, and into either the left or the right end of the ram that is attached to the tiller.
    Do you know how rams work?
    What isn't shown is better detail of the wheel parts. No rams are shown but a "helm pump" (see drawing) is actually doing the same thing as the tiller ram but in reverse.
    All you need to know is that fluid is pumped in a different drection depending on which way you steer.

    This raises the obvious - "if you have to ask" thing, maybe some serious study is in order, as this information is commonly available at many resources.
