Make a small bell crank with a ratio to match the display |

Yep, I was afraid that was gonna be the the suggestion. I think I'll just remove it. I'll save a few ounces of weight while I'm at it. |

Post subject: | What tool do I use to swage a fork end fitting? |
It looks like Im going to need to run down to my local machine shop to get these fork ends swaged (for my rudder cables). In case I've missed it, I just wanted to ask if there was a reasonably priced tool I could purchase to do this myself? Attachment: fork end.jpg [ 6.65 KiB | Viewed 9639 times ] |

Not only do they need to be swaged, but go no go tested. Some boat yards can do it. |

I think this is the only tool I have seen and it's not what I would call affordable: https://www.aircraftspruce.com/catalog/ ... kkey=46640 Is it feasible to convert to nicopress? Not as sleek and pretty but every bit as effective and a lot cheaper to work with. Then again, I bought my rudder cables from Cubes. |

I have rudder cables in stock. Having said that, I have no idea if there is a difference in length by moving them outboard Cubes |

Outboard is about .75 longer than down the center. |

Yep , as Bob sez . I took some of my cables to a "rigging outfit" that does just that . They had a hydraulic press that squeezed on the fittings ! When they found out it was for an aircraft they weren't even going to charge me , but I told them I knew a few Air Force guys and they said that will be $5.00 ! OH MY ! If you don't have a commercial boat yard that does this sort of thing , then try a "rigging outfit" that does cables , etc. for commercial cranes . RB |

The S-18 cables are about an inch longer than the ones I replaced on my T-18. If Ryan's T-18 is like mine, and there is nothing to say that it is, then the S-18 cables might fit the new routing. |

We'll see I guess. Thanks for all the outstanding input. I have gone back and decided to route my rudder cables down the center as per plans. The per plans method is a straight shot from the pedals to the rudder attach point. Its just so clean and efficient, i like it too much. I'll just have to lift my foot over the rudder cables when I want to stretch out on those long cross country flights. I do that now with my flying T18 and it doesn't bother me. I find that future maintenance thoughts drive a lot of my build decisions. That's why I removed the elevator trim indicator too. Just one more thing to have to fix/repair. |

Ryan, you're a man after my own heart. 100% agree. |

FWIW, I have S18 cables in stock as well. Jeff, they should be exactly 5 inches longer than the T. Cubes |

You might be thinking of flap cables which are exactly 1 inch longer. Cubes |
