Bear in mind that the diameter of a plug follower MUST be precisely the same as the plug for it to be effective. I get 12.65mm which works fine for most cylinder over here in the UK
Alternatively, you can just use another plug from a particular lock - Not the best thing to use but it works fine.
The 1/2" fits well (google tells me 1" = 25.4mm, so I'm sure we're talking about the same diameter). I took the plug out of one of the locks I'd be using it on, took the lock down to the place where I bought the dowel, and tried it out for fit. (Canada is supposedly metric, but I guess we can't quite bring ourselves to commit to it, so we still use inches and pounds at times.)
