I'm working on an old piece of American iron. There is a gear which is driven by a ratchet/pawl. The ratchet pinion is fastened to the shaft but the gear is free to rotate on the shaft. The spring keeps the pawl engaged. Here's a pic:
The image quality isn't the greatest - sorry - I grabbed it off of Youtube. But it should convey the idea. As you can hopefully see, there is a spring which keeps the pawl engaged.
My machine is missing this spring. Truth be told, I'm not 100% certain that the spring is original. The bolt and nut holding the pawl onto the gear spoke don't look like the rest of the fasteners on this machine.
Anyway, I have never made a spring. Now I have to make a sort of complex one. Can anyone walk me through exactly how to form and heat treat a spring like this?
