    Default vibration deadning of aluminium t-slot

    i was searching the net for how to make aluminium foam , and found some answers

    stir in 3% calcium carbonate to a batch of molten aluminium at 700c for 70% foam
    calcium carbonate is a pool PH adjustment additive

    thought it might be useful as a vibration killer in t-slot tubes used to make CNC's

    And then what do you do?

    Just pour it into the tracks and then skim the surface?

    The term 'grammar nazi' was invented to make people, who don't know their grammar, feel OK about being uneducated.
