Aggressive rapping can break smaller sand features. It seems better to do a lot more rapping with a lighter bar
I think I will try making up a template to sit on the sand around the pattern and hold it in place as I pull up the pattern, not sure how this will go.
I was so concerned about the metal post I was casting around, I forgot to preheat the muffin tray for left over metal ingots. Lucky it's been warm, no condensation to bite me. 😳
I'm getting a better feel for how much water my sand needs, I suspect this varies by sand, and it's very much a feel thing. The sand should still be possible to sieve, but not as easy to sieve as dry sand.
