worked on the burner today

[Mayhem]

slightly off topic but in line with Dave's last post. There use to be a TV show that looked at certain things that had been done throughout history and tried to replicate them. One was trying to figure out how they irrigated the hanging gardens of Babylon. The most plausible explanation was large screws that lifted water up the terraces to the top. They ended up casting one in the desert out of bronze using only the technology and tools of the time. I think they failed to get the water to the top but it was interesting to watch.

Oh and Rick, you better video your foundry build...
