    Thumbs up Sturdy DIY CNC Mill made of Fibre Concrete

    Hi Machinists,

    Here a video about my recent DIY CNC build, where I experimented with Glass Fibre Reinforced Concrete.

    Looking forward to your thoughts and comments

    Using some variant of concrete for machine tools is something I'm interested in, but many here will consider it a "home shop" experiment, so don't be discouraged if you get some negative feedback.

    Edit: Took a look at the video, and it's a very small home-style machine. It looks good for what it is, but it's really not appropriate for this forum.

    Nice effort.
    I'm not impressed yet that this should be in woodworking.
    Can you show examples of woodwork you have done in the past?
    & describe what the wooden parts you are making are/are for?

    if you watch the video, you see it used for woodworking. I don't think that there's any intent for metalworking, hence the woodworking forum.

    Does concrete absorb and/or give off water vapor? I'm wondering if that could be a potential problem long term for steel components? Seems like the epoxy/granite stuff would be impervious.

    Understood.
    However, if it was a full on CI & steel build would the project belong in woodworking, General, or metal working?
    Ditto concrete.

    However, anything that promotes woodworking is welcome. Posting on here, it would be nice for him to show & describe what he makes with the machine; and discuss the woodworking aspects.

    There's also Don's imperative against non-industrial equipment. Which you will be aware i ignore so long as somewhat interesting (in the complex or accomplished sense) is demonstrated & described.

    Should everyone who builds a youtube machine get to post a link to it here with little other participation?
    Or do you think that would eventually lead to more participation overall?

    I'm pragmatic, and interested in what the OP has to say on the subject as well.

    Hi Richard, thanks for the interesting question. While the concrete cures the water therein will partly condense, but most of it will actually be bound/consumed to the cement during a process called hydration. The cured concrete will not give off vapor. For my machine I also have an epoxy coating that seals the machine.
