Steering cable Teleflex

Postby JAMES » Mon Jun 19, 2017 3:49 pm

I have bell crank steering now which Ive been told to try different stuff to get the steering correct it makes my arm sore as hell taking out for a couple hours due to the fact is it's hard to steer one way then the other so I'm pretty fed up with it I think I'm going to go to cable I ran the cables before never paid attention to the stainless steel vases the regular is there a big difference

As far as added resistance (wear on your arm), there should not be
any in either case when they are new and things are set up correctly.

The practical differences that immediately come to mind are:
a) Teleflex cable has about 8" travel vs about 6" for typical PTO cable. This is a good thing.
b) The Teleflex will cost more upfront, but will be smoother for much longer, IMO.
c) The Teleflex cable will likely need a couple SS tabs welded on the ends to use in typical air boat fashion, where the PTO cable would not (but the rigging would still need mounts, if none previously existed).

If you are switching from a bell crank system, you are likely in for a little welding in any case if your rigging was not initially built to use cable steering.

If that is the case, and especially if this is a boat that you intend to keep, I would view the Teleflex as the far better, and easily preferred option.

If your harder to steer one way as opposed to the other, cable is not going to help.

James is your issue the geometry of the setup?

3) conneting points between rudders
4) connecting point for bell crank or cable end
5) achor point on cage for bell crank or cable and angle to connecting rod
6) fulcrom point beside driver
7) distance from fulcrom to lower connection point
8) anchor point for cable
9) locating center point of stick travel to be centered to center point of arm movement
There may be more .....

Do your rudders have trim tabs?

I have no clue about this bell crank **** it's on my last nerve but somewhere along the lines in your post it's something they're
