In the attached image is a rough sketch of the scenarios available to me for connecting the tiller arm / rudder connection to the below decks sail servo - using strong cord.
Normal connections are either
A to C ...... B to D
or
A to D...... B to C (using cord crossover)
However because the run from the tiller arm connector to the servo is about 8 inches I am considering putting two brass pulleys into the sequence.
Being useless at geometry (and drawing) I would appreciate any guidance as to which position for the pulleys might be best. Additionally would infact using the pulleys be beneficial or not.
Using the pulleys the connection sequence would be
A, E, C ..... B, F, D
or
A, G, C........B, H, D
Hope this makes sense - I have to consider one of these options because space for the servo is restricted within the hull of this particular cutter.
The sketch is not to scale, and usually the servo arm has dimensions equivalent to the width of the connector bar on the tiller so a straight cord run is obtained.
- using pulleys would mean the arm can infact be lengthened
thanks
