    Hi, I want to build this for my school project but a copper rod costs too much. Do you have any idea if a hollow copper rod would work as well?
    Best regards,

    Sorry for the late reply. It will work but the brake performance will be reduced.
    Aluminum rods may be better than hollow copper rods. It is better to buy one as a sample and experiment with it.
