Newbie Question: Rigging Problem

Hi! For my animation I’m making a fan and I’m rigging it. Everything goes haywire when I try and move the bones! I’m a newbie to rigging so I have no idea what I’m doing wrong. Here are some pics to describe my problem:

Thanks! Can any of you give me some advice or a solution? In case you want to take a more in-depth look I’ve also included the .blend file in the mediafire link below:

Thanks!

Hi Poofo…

For mechanical models… it often pays to just parent parts to bones… I have made a stripped down model of your fan to fit the 960k limit here…

Thank you!!! That solves my lifelong dream of finding out how to rig mechanical models!
