I scored my air compressor from a dumpster, but I had to go home for tools to remove the motor, & compressor pump from the tank and I had to lower each piece over the side on a rope...

Cool score on the ironwood, that's expensive stuff. On a similar note, I also scored two heavy factory trolleys from the same dumpster the compressor was in, I grabbed them because the decks were made from 2x6 oak planks with great patina. Still haven't figured out what to do with the wood.
