So we made our keggles tonight. Found a link on here that shows how to get the ball valve off the top of a keg. We did that prior to grinding the top off the keg. So, I see how to get that ball valve off in order to fill the keg, but how do you get it back on? I popped off what looks like a very thin metal lock washer that looks a little like a spring. How in the world do you get that back on?
