Science Buddies: "Ask an Expert"

Hey, Science Buddies. I just wanted to know if anyone had step by step instructions on how to build a parabolic reflector. I am doing the The Point of a Parabola: Focusing Signals for a Better Wireless Network project and I did not understand the instructions from the link ScienceBuddies gave me.. My project is due at the end of February. Please, step by step instructions on building a parabolic reflector. I have all the necessary materials I just need a more thorough explanation. And, I do understand the parabola concept. P.S, I'm in the seventh grade so let me know if I should choose a less difficult project.

In doing a simple Google search, I found the following websites that may help:

Good luck.
