Copper finned pipe cleanup

They are 15 lbs of copper in each pool heater.
Some have cast iron header ends, some have dirty stainless headers, but the best is the ones with Brass headers.
We do two or three pool heaters a day for the month of May and June.
I will post pictures this evenings of complete breakdown. They are very easy to do with a 5/16 bit on a drill. The hard part is getting the headers off.
I use my chop saw but can be done a hammer or sludge. Another easier way is sawsall or axe and hammer.
