This is a one-off bellcrank that secures the cables used to control the ailerons of a Jenny that is being built from scratch at the Minnesota Civil Air Guard Museum.
The pattern for the control rod bracket was made by an old timer at the Minnesota Civil Air Guard Museum, I took it to my shop and cast it out of aluminum.
Behind the control rod bracket you can see the finished bellcrank.
I also made the patterns and cast the wing skid brackets.
