Spiderman 2 Doc oc claws
 

Ok, i made doc oc's claws, and one finger of the claws have 4 joints to it, but when i bind skin, and then rotate maybe the first joint up and down, the second joint will me all messed up, it would be all skinny on one side and stuff, please help, if u need the file i saved it on, ill give it to u, but first tell me if u can help me from here

Two things. Since you're working with non-organic models, use a rigid vice a soft bind. Second, study up on weights. Weights define the distance from the joint that gets influenced by a given joint, and how many joints have influence over a given section of geometry.

I think another way to go about this could be to make each joint of the finger as seperate objects and just parent them to the bones...

they are seperate objects, here ill send the file and u check it out

You have some potential animation problems with your model. Unless you want the metal to strecth, then you will need to add some type of segmenting to allow more movement. There is nothing in between the tentacle section to act as a joint (visually I mean), so that if one section bends away you'll see space between them. There is too little space between sections, which either limits flexibilty or means section will fold in each other.

thanks for the advice, i appreciate it!!:)
