Diameter of stock bail spring vs. bail trip spring appears smaller?

Many of the Ohana have had to custom up some springs in a pinch, so I am sure lots of helpful tips will follow shortly. I am pretty confident your local Ace/True Value etc. will have suitable material, and as far as winding find a tool of suitable diameter (dowel, pencil, screwdriver, socket, socket extension, the list goes on and on). - john
