    Copper soft jaw faces for lathe chuck

    I needed some soft jaws for my lathe and after seeing homeengineer's aluminum jaws:

    Aluminium soft jaws for the four-jaw chuck

    I decided to make some for two of my chucks. The first set was for the 3 jaw and has an added plate
    to protect the back of the part you are turning. Takes a bit more work but the added protection is worth it
    for some projects:

    Then on to the easy type. Just take some measurements and transfer them to paper. No measuring tools required, just use one of the jaws:

    Cut them out from copper sheet:

    Start the bending process:

    Then I always save a small poster board template for next time, and there will be a next time.

    Cheers, JR

    Thanks Andy, the template is from my background in model aircraft. Multiple ribs etc require a simple template since so many are made and
    it is easy to just trace around the original. Same with broken parts. Just glue them together and make a template for laying out a new one.

    Cheers, JR
