At the top of the control column is the 1" dia. brass tube (bent)handle...This fits to the phospher- bronze ( Gunmetal originaly,which is a bronze ) socket into which the top of the control column fits. ..two sockets grow out of this and over these , the brass handle fits....All joints are taper pinned and then sweat / soldered ........In "Theory".....The handle is supposed to be able to be " SPRUNG " over the sockets..However this is patently impossible , and so it has been made in three parts with an additional tube liners at the joints which are (hopefully) invisably braze/welded together and cleaned up after.......The actual Bronze socket was originaly a G.M. casting , however in this case I decided it more economical to machine this from solid bar , and finish with file etc...than to make up a complex pattern , for a one off part , and then this would require a machineing fixture to hold it...etc.etc.
.....Anyway .here are more photos
