Listers - have a problem here and can't figure it out.



I measured the hole in my side skin for the rudder cable outlet fairing as follows per plans 6-B-4 (08/05):

395mm from the back of the fuse to the center of the hole - 20mm wide; 

8mm high, bottom flush with the top of the lower longeron



This measurement conforms to every picture I can see - including the side view and the end view on page 6-B-4.



Interestingly, if one looks at 6-B-4(2) - the fairing - and mentally moves it up to the side view directly above, it immediately becomes apparent that the opening ridge in the fairing is not going to fit properly over the hole.  (AKA 20/20 hindsight) 



Either I am completely missing something, or the plans are wrong.  Either way, I need help!  BTW, I have already cut the 20x8 hole, so if you tell me I have it in the wrong place and should do something different, please suggest fixes as well!

You'll probably have to trim the bottom side of the fairing in order  

to center the fairing ridge over the hole.

Michael,



As I recall, the fairing must be trimmed, both on the bottom and the top to fit properly.

Thanks for the prompt responses Bryan and Jay.  My concern is that the place I opened up the side skin may not be the right place for the rudder cable to come through.  I assume it follows a straight line between two points, but I don't know those points yet!   



Have other people cut the hole in the side skin in the same place as I just did and then just adjusted the fairings to fit?  If so, does the cable run fine through that hole?



Thanks, Michael in NH

Hi Michael,



 Did you include the nylon fairlead with the fairing?  I think the fairlead allows for the cable to make a turn from its origin to the rudder connection point.  Even if it is straight at some point, it will make a turn when the rudder is moved.

Don't your plans call for a plastic fairlead there? Each rudder cable  

passes through two fairleads, one just behind the aileron torque tube  

and one where it exits the rear fuselage. The fairleads allow the  

cables to be routed through the fuselage without rubbing on each  

other or the airframe.



The left  rudder cable goes to the right side of the rudder and vice  

versa. One cable passes through the front fairlead a little bit  

higher than the other to allow it to pass over the top of the other  

where they cross in the rear fuselage. There will be a small change  

in direction at each fairlead.



The location of the rear fairleads isn't very critical but the closer  

you get to the ideal spot, the smaller the change in direction of the  

cable and less friction.

Michael,

You should have little if any vertical misalignment, but the horizontal 

sweep of the rudder horn will

cause a few degrees rub within your nylon guide at that point.  If you 

have more than 5 deg vertical out

of track, I'd recommend you find out what that amounts to and make 

adjustment to your hole positions.

Should look about the same as the link below.

Thank you all for the responses and pictures, but I think I still need a bit of help.  I do have the nylon fairlead there and I understand that it is to prevent rubbing, but I obviously want to drill the hole in generally the right place so the rubbing is as little as possible.  (Of course, at this stage I don't really know the precise location of the two points that will be connected.) 



So how about this question:  How far above the bottom longeron did you center the outlet hole?  



As I mentioned, my outlet hole is 8mm high and flush with the top of the longeron - so my answer would be 4mm.  I am very concerned that it should have been higher! 



Thanks, too, for the pictures from everyone.  Does anyone have a picture of the opening before they attached the fairing?  (ZAC's guide only has a very close up picture that doesn't show the position, just the shape.)

I don't have access at the moment to measure it but as you can see from this photo...



http://www.peoamerica.net/N601WR/html/fuselage_1_55.html



...it is significantly higher than flush with the top of the longeron.



I also ended up putting the nylon inside the fuselage. It looked better and made more since.

The hole in the attached picture is much higher than mine is on my airplane.  My hole is just above the longeron.  The lower rivets in the outter cover are in line with those through the longeron.(on my application)

Thanks Fritz - any problems with yours?  Does the cable seem to come through smoothly without too much angle?

Mike-

     Just looked at my project,  and your dimensions seem right. The only thing I can think of is,  you're not removing all the bearing material inside the cutout. Only a slot a  little wider than the diameter of the cable on the centerline of the  opening.

MIke-- I have had my rudder on several times, with the cables connected.  I have not noticed any bad angles to the cables.  Do you have the slot (not hole) in your "nylon" bearing as well?   My work was done according to the plans dated 12/02 6-B-4.  The only thing I did different was: 6B4 show a long slot in the rudder cable fairlead, I made an "oval slot" to ensure there was no contact with the fuselage skin.
