Training for Finger Cracks

Let's say I'm trying to send my finger crack project at the creek, what are the best exercises/workouts I should be doing to feel good on steep finger cracks?

1.) Open desk drawer
2.) Insert fingers
3.) Slam desk drawer
4.) Open desk drawer
5.) Repeat steps 3 and 4 for every 2 feet of project for each hand
6.) Extract fingers
7.) Close drawer
8.) Ask your self why

In all seriousness Id like to know what other folks do as i do enjoy crack climbing...

Do you have a crack machine or access to one? I'd say that would probably be your best bet.
