Hi everybody,
I just started picking locks, and ended up buying a cheap kwickset deadbolt to practice on.
Since I wanted to be able to remove and replace pins as I got better, I needed a plug follower, and didn't feel like paying $3 for a 4 foot length of dowel.
What I ended up doing was wrapping a piece of paper several times around a AAA battery and taping it up real well (including kind of cutting and folding it over the end), and what I ended up with was a perfectly functional plug follower without having to buy one (I've since started at 2 pins and worked my way up to five, although I can't do 5 every single time yet, still need more practice).
Just wanted to put the idea out there in case anybody else wanted to try it.
