[QUOTE="ekvh, post: 214537, member: 1179"] I wish I had taken pictures of the last set of copper when I switched to the 1200 heads. One thing is clear that the water jacket holes are not lined up very well and cut into the cylinder surface. If I order any more, I will ask him to move the ring of water holes out a little. I also wonder about cutting open the trapezoidal holes. That said, it doesn’t look as though it was leaking where the holes are over the cylinder wall. The other part which might be a factor in using copper is the annealing process. With just a propane torch, you can get the copper orange, but not all at the same time. So when you finish one side and move to the other, the first part is already cooling. The last time I did it, I tried to keep waving it back and forth but a simple propane plumbers torch wasn’t enough heat to keep it all orange and quench quickly. Dave, how much additional energy- heat is used or created - during cavitation? Maybe a zero factor since you change states liquid to gas, but then turn it right back to liquid. I remember taking students to a zero vacuum machine and showing them a room temperature container of water, reduce pressure to see it boiling, then removing it and feeling the water temp to show it wasn’t heating up as normal water boils like on a stove.
