Combined with the yoke base mechanism this package represents a low cost solution for building a high quality replica Boeing, Lear or generic type yoke control column with pitch and roll potentiometers ready to wire to your interface card. The elbow unit consists of a solid Trovidur PVC circular block machined to house a high quality needle roller bearing for the hollow axle. The hollow axle will allow yoke button wiring to be be fed down the inside of the yoke column along with the potentiometer wires which are supplied. The flange has two rows of threaded holes for mounting a replica or generic yoke handle. The flange has a pin for limiting rotation to 180 degrees. The potentiometer drive for roll motion is geared at 3:2 so the potentiometer rotates 270 degrees. There is a small pulley on the rear of the unit with a locking device to grip 2 mm wire rope, this is for transmitting roll motion across to the second yoke in a two position simulator.

The last two pictures are the yoke pivot which is a base mount for Boeing type control columns. Any diameter of column can be attached to it just by drilling two holes through the column tube. The prototype has 50 degress of motion and the gear ratio is 5:1 so it rotates the 10Kohm potentiometer 250 degrees. The pitch angle can be altered by request as it just means a slight alteration to the CNC file.
