    Default Acetal Faced Machinist Hammer

    G'day all,

    What's the best method of attaching black acetal to a machinist hammer(s) that I'd like to make.

    Thinking of making two, one the middle part brass faced with two acetal ends and one aluminium with two acetal ends.

    Cheers,

    Jim

    Thread the acetal or the ali?

    I'm thinking ali?

    Is there any glue that sticks to acetal?

    I think this is what you are intending making: https://www.youtube.com/watch?v=Q6X4HIDmJsA

    He puts the male thread on the Acetal. I would put it on the brass.

    Epoxy, but not very well and only if you really rough it up.

    This thread inspired me to make a knocker similar to that shown in the video. I used M10x1.5 thread. If I can find some lead I'll replace the ali end with lead. Can you tap threads in lead?

    Here is my brass and Al hammer.
    The threaded rod is SS.
    Wood from the branches of a red gum that grew outside the shed for 30 years before being taken down.

    No

    But tin the brass end. make a mold and pour lead into it. The lead fuses with with the tin. I used hard lead in my hammer.

    Thanks eskimo. I did a bit of reading online and the consensus was it's a nightmare to tap it. I'm going to buy a scuba diver's weight and have a go at casting it.

    Hi Jim,
    Here is a hammer I made that has removable ends. The 4140 alloy steel body is bored on each end to accept the stems, which are each secured with a single set screw. This particular hammer is actually for sheet metal shaping, and the removable ends are actually CP dies used for metal shaping. I manufacture 13 different die shapes in both black 6/6 nylon and 4140 Heat Treated alloy steel. If I were just installing flat hammer faces then I would make the stems a press fit into the body. I use this method for some of the specialty hammer dies I make for Pullmax and Planishing Hammers.

    You can see some of this tooling here:

    Hi Bob,
    Very nice job on that hammer head. Did you use a lathe to turn it after the glue-up?
    Thanks,

    It would have been a ideal to turn it up on a lathe but I made it before I got my lathe. It was rough cut with a TS and then I used a #40 grit belt on an upside down belt sander
