Boeing 737 rudder pedals construction

Those hydralic/spring struts used to close screen doors have a screw on one end to adjust tension.
I wonder how those would work?

I believe Gwyn used those with a very clever design in his yoke mechanism. You can find pictures in the Photo Gallery section I believe. One thing to keep in mind is that those things are normally fully retracted instead of fully extended.

Unfortunately, most of the fish scales I had recently , I washed down the sink whilst cleaning the fish for the BBQ. Still, an ingenious idea.

(Sorry I'm on a business trip, and forgot my tablets, was that tablet PC, or tablet that drops down on FSUIPC buttons menu)

ps its still sun below the yardarm time here, in case you are wondering...

pps sometimes lateral thinking can be viewed as being insane. (or was that lateral viewing..)

Hey Maurice,

Nice job on the rudder setup. Have you thought about motors to automate it for AP; it looks like if you attached a reversible motor to that rod that goes between the Capt and FO rudder sets, it would cause them to move automatically. You just need to add an electric clutch to engage the motor when you want it on for AP and off when you move the pedals by your feet. Thus, that relieves the pressure of the motor.

Hi John, as far as I know AP doesnt move the pedals in any way However the motor can be used for rudder trimming.

2 Maurice - the pedals are very good. You can call me insane builder, so I will not grouse about the load forces. I think one thing you have missed - pedal adjustment system. Its very easy to build - you need to have your cam mounted on the thread. The same design is used on the real plane.
I think adjustment system is even more important then motorized trim.

True! I used two screen door closers to center the pitch motion and it works and feels great. I used two that were different types and I've just bought two new ones which will be fitted when I install the new yokes from Roberto. They are finished and are being painted gloss black in two-pack by a pro painter mate at the moment, I hope to fit them this coming weekend.

What is your dimensions? btw I am an engineering student and I found your design to be the best after about 3 days of looking though designs. Good Job!
