Elevator bellcrank cable connection

[PoconoJohn]

I'm trying to find the right part to connect the elevator cables to the elevator bellcrank. All I can find is AN115 cable shackles. They don't seem large enough to have two cables connected.

Once that's figured out, is the cable looped through as seems to be on the plans, or is there a better way?

Thank you,

John C

Are you talking about the bellcrank inside the fuselage, behind the pilot's seat?

Browsing around Westcoastpiet, there are plenty of different setups at that bellcrank. Here's Chris Tracy's.

Yes, that's it. I see a shackle on the top right. I'm trying to figure out how to best connect the cables. I'll look around for photos.

John, note that you can use some AN111 cable bushings through AN100 cable thimbles to secure the cable ends to the bellcrank by passing a bolt through them. Various ways to skin this cat.

Thanks! I may be back with more questions.

John, I somehow managed to build my Piet without using a single AN115 cable shackle. I used pairs of #50 motorcycle connecting links throughout. They fit AN3 bolts perfectly and can be widened or narrowed by using however many washers you need. They are also much, much cheaper than certified thimbles, as you can buy them from places that supply drive chain systems and probably from your local motorcycle shop. I bought mine from Grainger. If you'd like, I'll snap some pictures. Cheers, Ken

Thanks Ken! Photos always help. I'll go to Grainger and look around.

John,

I haven't found a picture of my elevator bell-crank assembly. Here's one taken of the rudder horn that might give a sense of the flexibility provided by using combinations of motorcycle connecting links. (Disregard the angle-finder. This was taken as a set of photos when I was dialing in the H-Stab angles of incidence.)

Cheers, Ken

[PoconoJohn]

I can see the set up clearly. Thanks!

I have a complete,behind the seat, bell crank assembly available.
