    whats the deal with all this epoxy base stuff

    Hey I have read a few threads on machines being built out of epoxy. Much like I guess a typical milling machine would be cast out of steel people are now casting with epoxy.

    I plan on building a machine out of heavy I beams. However I got to thinking if I could cast my beams out of epoxy that might be a better alternative.

    Anyone have much info on this stuff. Where to get it or if its even feasable. can you machine this stuff after pooring.

    thanks

    Certainly works for me it's not new.

    I've been machining on epoxy granite bases for over 10 years (Diamond Machining)- cuts down on vibrations.

    Here's what my machine manufacturer says:

    The machine base is constructed of an epoxy/granite composite. Epoxy/granite is made of 95% crushed granite particles mixed with an epoxy binder. It provides excellent thermal stability and vibration dampening characteristics, as well as allowing the incorporation of swarf extraction tubes and wireways into the molded structure.

    The base is isolated from its fabricated steel frame by a passive, three point, pneumatic vibration isolation system.
    I love deadlines- I like the whooshing sound they make as they fly by.

    well it sounds like great stuff but is it feasable for someone to cast something at home. Im not familiar with the stuff so im not sure. I would like to make the main frame portion of my router with the stuff but have never seen it sold nore gotten a definate answer as to it being done by a non-professional.


    Heck I really like the idea. If I could find some type of poorable epoxy I would try it with that stuff. I think it coudl be reinforced just like concrete with rebar etc.

    any ideas
