When I launched my coil hand spring and plunger, I found the spring, but not the plunger. I made a new one our of a piece of drill bit, all rounded up and polished, etc. THEN, I found the lost plunger (I had thought that it had gone across the room, but it was right at my feet the whole time). Now I have a spare. That means that I will never lose the plunger again, just the spring...
