ZM, your benchtop is my wife's worst nightmare - sometimes in the middle of my projects, I turn our kitchen table into that

Anyway, can't talk now, I have to find a big flat rock to cook some sausages on

On Topic: how long does it take for that rock to heat up enough to start cooking with?

Darn 😱 Where do you stumble across these big heatsinks ? No matter where i turn, it seems like the only place to get them is at Conrad, and i dare not even think about the postage.

BTW congratulations, they look really nice 🙂

Just lucky I guess😉
Conrad's are not too bad regarding postage.
