There's been some great advice here but I'll add my two cents.
I think the most beneficial part for you to practicing wrist manipulations alone wouldn't be to actually try and "do a move" but rather look at your hand and wrist and study the anatomical structures of it. Feel the way your own wrist and hand moves, here the weakest points of the mechanisms are and really commit that deep into your instinct. To me, a wrist lock isn't so much about "doing a move" in a pre-determined pattern but practicing the "move" is simply to instill in your muscle memory the anatomical workings of the wrist. When you fully understand that, like a walking anatomy chart, then you will know how to manipulate a wrist in an infinite number of positions and you will see "wrist locks" in all parts of fighting, self defense and martial art techniques.
So to sum it up, its less about learning a "move" and practicing it but more so understanding the biomechanics of the wrist and knowing what it can and can't do, then forcing the other persons into the "can't do" category. I hope this makes sense and is helpful.
