All recommendations are welcome. In particular how to vibrate a two part mold without it breaking apart. I did not weigh the mix and water, but i suspect i used too much water. Also added about 2% plasticizer.

    how do you vibrate? do you try to vibrate your whole mold? like using a “concrete vibrating table”?

    maybe you can build you a equivalent of a “handheld concrete vibrator” in even smaller, and just put it into the concrete?

      Well i just tried holding the bottom of my multicutter onto the mold, probably was not enough. Maybe if i put the entire thing on a plate i can vibrate the whole plate somehow…
