Noobie in search for a nif tester (animated object)

[sundabar21]

Hi! I had made a Shaduf with Blender (a shaduf is a well pole) this is a first time for me making a animated object (activator), i try animated it with shape keys and it gets disorted, after that i experimented with simple animations but i was having trouble with the rope and it ends being a armature animated object. I'm not sure i do the thing "the right way". Sometimes when i activate the objects it dissapears. I don't know why.. Maybe you can look and tell me if is something weird with the nif (or if there is a better way to make the animations). If you know about some tutorial for animating objects with skeletons i'll be a very happy person. I've read th "Basic Animation tutorial" and a bunch of people's posts in forums , but not sure about the aplication of NonAccum and Bip01 bones to animated objects. There is the link of the file https://www.4shared.com/rar/dZGHdxfuce/PShadufAnim.html
