Russian Typhoon Submarine

Part 4b - Rudders and associated hardware (continued)

	Before shaping the movable part of the bottom rudder (part 2), a 1/8" brass rod is inserted 3" through the top. It will eventually be secured in place using CA glue making for a very tight and secure fit. The rod will extend up into the center fin through a 5/32" piece of brass tubing to accommodate the control linkage clevis assembly. But first, I must make sure everything will fit together. There´s no sense gluing everything together unless it does.
Here, you can see that I´ve manufactured a control arm for (part 2) of the bottom rudder assembly. It was made from a piece of brass sheet and then soldered to the brass rod. Holes were drilled not only for the brass rod, but also for the clevis.
	The linkage connecting the movable parts of both top and bottom rudders (part 2) will consist of two (2) clevis´ (one soldered and the other threaded), one (1) steel rod and two (2) control arms. Here, you can see the threaded clevis´ with steel rod and also a package of Dura-collars made by Du-Bro. You´ll see where these fit in later on!
Ok, now for the down and dirty ... the bottom rudder (part 2) is connected to a soldered clevis ... which is connected to a steel rod ... which is connected to a threaded clevis ... which is connected to the top rudder (part 2) control arm ... which has a Dura-collar soldered onto it ... which will hold the top rudder (part 2) brass rod ... and be secured with a set screw that I can reach from within the hull. And ... if this doesn´t work ... I´ll think of something else ... just kidding! And, of course, there´s more. The top rudder control arm will be connected to a threaded clevis ... which will be connected to a steel rod ... which will be connected to a servo motor inside of my propulsion watertight container (WTC).
	I´ve shaped both parts of the bottom rudder and installed a piece of 5/32" brass tubing in (part 1) to house the 1/8" brass rod. As you can see, (part 1) will be bolted to the hull!
Here, I´ve temporarily installed both the top and bottom rudders to ensure an aligned fit. The linkage assembly in the center fin will eventually be hidden from view. Next Step - Part 4c - Rudders and associated hardware (continued)
