There are really only 2 basic cranks. Due to the magic of both spins and going against the spin (see Skippy’s Article) there end up being 8 different combinations. Doing the basic with the spin cranks are easy to learn.
Here’s one: delay counter on your left hand palm up. Now lift your hand up and twist at the wrist so you are delaying palm down. Continue the twisting motion until your elbow it pointing up and you are delaying palm up again (only now your hand is inverted). Now bring the disc back under your arm armpit, twisting your wrist so that it returns to the original delay position (palm up). Basically you pull the disc under your arm.
The other one is to reverse the order. This one is easiest counter right. Just rock the disc towards you and swing it under your arm. Once your hand is inverted lift up and untangle your wrist.
So taking the examples above and doing them clock makes 4. But it gets tricky when you do them against the spin. IE Doing the counter motions/hands with a disc spinning clock. Thus there are 8, 4 with and 4 against.
Here’s a tip to make it easier to get the motion. Delay a counter left. Set it up about eye level. Quickly invert your hand and let the disc land on your nail. Let it fall to the rim. It will naturally circle under your arm (hence with the spin). This will teach you how the motion works. Just remember a true crank is center all the way.
