Thanks Brad, that makes a lot of sense, and will help us evade any future problems like that. Also I will try the casting when we are able to meet again for robotics. It is snowing here, and we haven't been able to meet since friday, and if school is out tomorrow, we can't work tomorrow either. But, when we do go back, I'll be sure to try everything out, and if it works I'll let you know. Thanks for all of the help from everyone who offered solutions.
