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.

Consider lubricating the inside of the mould so it’ll release better and some reinforcing mesh. eg, cooking oil spray, raw fiber glass.
Ty, used spray oil, seemed to work ok
we used a custom mix that was affectionately nicknamed ‘the grog’, but it was mostly wd-40 and white lightning lithium grease.
