Do a Google search on DIY compressor vacuum pump. Yes, there's a site out there. But really it is simple. Don't saw, but rather cut the copper tubes. Sawing copper might induce copper filings into the compressor. I'm sure there are many guys that have sawed theirs off. Make sure you leave the copper at least 5 inches long. In other words, don't cut the copper to short. Remove the power wires (reuse), remove the mounting bolts and your done. If you see a starting relay, or starting capacitor, or overload protection in the power circuit, keep those for reuse. In the picture above, you can see 2 small items which are just that.
Don't lay the pump on its side because it has oil inside that will leak out the copper tubes.
