I am making a mouse trap car for my science project and I am trying to attach the cds to the car. I am having the problem of keeping the wheels strait and aligned. I am using a cd with a grommet in the center. I am attaching that to a screw which is a part of the axel. I don't have and photos and any help would be great.

Thanks

Thanks but I have a different problem now... I attached the cds fairly strait but I think the axel may be off so the car goes off to the right. Is there a quick fix to this problem? I'll use the link you gave but do you have and idea about this problem?
