Please Help: Creating New Weapons

Hi

    I am trying to create new weapons using Twilights component editor and am failing.  I created the custom techs to correspond with the new weapons, which show up in game, but the actual components will not.  I have no idea what I am doing wrong, be it choosing inappropriate pre-existing models for the new weapons or somehow not linking the components to the tech.  If any one could give me any advice or point me to a thread concerning a component editor tutorial that would be great.

Thanks
