Today I started machining the underside and the top of the prototype. I also ground it in three steps, grain size 80, 150, 320 and polished one corner.
It slipped off my hands one time and hit the rough concrete floor leaving craters at the neck and bottom in the soft material. I was not happy at that moment.
One disadvantage of these sand castings is that some pits are extremely deep, they will remain after polishing.
Does anyone have an idea?
