    Copper soft jaw faces for lathe chuck

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

    http://www.homemadetools.net/forum/a...029#post106174

    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

    To JJR2001,
    Are you the owner of JR RC Radios INC. for model aircraft? Just curious.

    No Owen, no relation at all. I did fly a lot of RC a few years back but I used Futaba Radios.
    Never had any malfunctions in over 10 years of use with 2 transmitters and 6 receivers.
    Great Quality.

    Back in the day '80s JR was a good brand of RC radio equipment but I never used them either.

    Now a days I do all my flying on the PC and in the shop with my mill and lathe!
    Cheers, JR
