Hello David,

You often see, nearly always, may I say, that they use a pianowire connecting rod between the two elevator halves.
Then they make the lever, for the push-rod by solder on these connection rod. Yes do silversolder!!!!

Wrong.................

Try to realyse what's happen when the solderconnection of the lever disconnects!!!
Yes, The two halves of the elevator still have on there last meters through the air exactly the same position, nice to know but not effective!

So

Each elevator-half you have to connect with the push rod,
Each elevator half you must give its own lever, that is the only safe method. You can not let the live of your airplane let depend on one single solder connetion on the connectionrod.
But now you have to connect two levers on the same pushrod, that thrue, but that's no problem. But do use double security!!

Between the two levers you solder epoxy two side copper sheeted circuit board AND WRAP WIRE around (that's the double safety!).
The little circuit board surface on the end of the levers. Thats the place you solder a bras bearing that has a good fitting with the rod.
Remove the copper from the circuit board on the place you can see on the picture.
This is my methode to isolate (electrical) the metal of the pushrod from the elevator connectionrod!!!

You've ever see this before? No I do not think so, own design.
Go to the Thread of the Taurus of Ed Kazmirski and look for the second quiz!!!!
