Yoke and colums. I wanted connected colums and yokes and after a long while I finely came up with a Idea while laying in bed. its basicly this 3" PVC pipe makes up the colum and conecting pices, should look like a giant U but spaced as far apart as your yokes are (40" for a 737 and about 42" for a 757/767)
on the botton of the U is a T -pipe section placed upside down with a hole drilled in the middle of the horizontal leg of the Tee. place a smaller PVC pipe (1.5") into the open T leg drill a hole also, place bolt threw both pipes, this smaller pipe is now connected to a cheep joystick mounted upside down in your pedistal. pushing the yoke and colum forward with push the joystick forward. now for turning the aircraft, you have to make a pully system that connects the two yokes to the smaller PVC pipe connect spring to the smaller pipe and to the 3" so the smaller pipe sticks up verticaly.
No remember tha the joystick is mounted upside down so left is now right, and vise versa. make your wire set up so when the captain turns right, the joystick turns to the left.
Some directions
Take PVC drainage pipe (I used 3") cut a 45 degree angle , then cut the colums lenghts. mount the two 45's together to form a 90 degree bend , but dont glue them yet. This is your mount for the yoke, it should look like a upside down L . The short end should only be a inch long from the bottom .
Cut out inside diameter of pipe out of a 2x4 drill hole in the middle slightly larger than the threaded rod witch will connect the pullys and yoke mount inside of pipe
