So, I did alot of guesswork and research, and came up with a pretty easy way to assemble em ( labor intensive though)
I've got pictures of two of the nutcrackers I did, Jake the Dog from Adventure Time, and Abraham Lincoln Vampire Hunter. Sometimes I've got pics of the process on one, and then next step is with the other, so bear with me!
Step 1: Planning out the shapes
Also, if you want to laser out the silhouette, it helps to hold up to your piece on the lathe to make sure the shape is accurate.
Both of these nutcrackers eventually got split in 3 pieces, head, waist and chest, but that doesn't mean they have to be distinct parts. Jake is all one round piece, and Abraham's coat runs down to his knees, so I didn't add a waist. On a traditional nutcracker though, there is a indentation that marks the where the chest is cut from the waist.
Step 2: Marking and turning the nutcracker
Suffice it to say, set up your block on the lathe (I used walnut), and mark lines where your indentations or features are going to occur. Then start shaping! (This was the fun part)
The last pic is one where I tried to do the parts separate from eachother. It didn't work out so well, because in the end the pieces looked funky put together.
