Rudder Cable Attach Bracket Question

[Helicopter D]

Are these brackets used on both rudder cable attach points? Of the two projects I have it seems both only use the one bracket and I'm not sure why. (Please disregard the condition of these parts as I am installing all new cables with new turnbuckles, there is something about 66 year old control cables that worry me

Re: Rudder Cable Attach Bracket Question

According to the drawings there are 4 D-26 connectors in the rudder cable system (drawing is REALLY old and faded). The D-26 is the little plate with two holes in it. At the front the cable goes around Ferrel with a button in it that is held to the rudder pedal arm with a bolt (no D-26 or turnbuckle). The cable routs aft through the pulleys and fairleads to the tail where it ends in another swagged end that goes through the eye of the turnbuckle with another Ferrel but no button. The fork of the turnbuckle on mine attaches directly to the rudder horn.

Although the drawing says there should be 4 D-26 connectors, neither of my planes have them (never noticed they were on the drawing since it took a magnifying glass to see it). The only reason I can see for them is if you have an eye end on both sides of the turnbuckle and need them to allow you to connect the single blade of the rudder tab to an eye end of a turnbuckle.

NO idea why you have TWO turnbuckles as I have NEVER seen one at the front. There are enough things up there to get you shoes caught on!

Interested in more info from anyone with knowledge. If I am out of configuration I want to correct it. It isn't like it would be hard to do.

Re: Rudder Cable Attach Bracket Question

I don't see many airplanes with the original sat up on the rudder cables. The 4 links that Hank is talking about actually have 6 holes for each piece. One hole on the end that goes into the fork on the turnbuckle. At the rear are 5 holes 3 on one side and 2 on the other. They are staggered with each hole being a little farther from the turnbuckle. This allows for a quicker adjustment of cable length to allow for taller or shorted pilots. I would guess that there is about 1" of adjustment from the front hole to the rear hole. The links also have a joggle in them to allow the 2 pieces at the front to go between the fork on the turnbuckle and the rear opens up to go on the outside of the rudder horn. Tom

Tom,
That actually sounds like a neat set up, especially for planes with different leg length pilot. Anyone have some photos of the way it goes together and a tracing of the links?

Dustin,

That looks similar to my 1946 BC12D rudder cable set-up. Those metal plates only on one side. Quite why I know not.

Re: Rudder Cable Attach Bracket Question

Ok, thanks for all the info. I now have all new ball bearing style pulleys, a roll of 1/8 inch cable and new 4 1/2" turnbuckles so my plan is to make new cables and just hook turnbuckle straight to rudder attach...and take a chance that it works. I was just puzzled because both of my projects only had the one bracket. Thanks Again!

Re: Rudder Cable Attach Bracket Question

I have the plates at the rudder horn. Will have to take a pic next time at the airport. I couldn't find one in the restoration photos...elevators always in the way!

Re: Rudder Cable Attach Bracket Question

Hank I can't find it but there was a sketch of this plate posted in the last week on the biplane forum. I will look tonight and try to find it, makes for nice, light, simple way to adjust peddle distance but it does change the tilt of the peddle. Not as big a deal for our heel brakes but has an impact on toe brakes.

If this works, here is what I have on my Smith Mini rudder pedals.

Re: Rudder Cable Attach Bracket Question

went to air port this morning and looked at rudder cables and 26658 has no plates jest turnbuckels at rudder horn

Re: Rudder Cable Attach Bracket Question

Larry, is this the one?

Re: Rudder Cable Attach Bracket Question

Close but mine has two plates on each pedal that split/bent to hold the cable thimble and there is no centered hole at the front. Minor differences but again these are on an experimental not my Taylorcraft.
