How do I work with copper tubing?

There are two types of copper tubing, soft and rigid. Both can be cut by the same style of tube cutter. Rigid copper isn’t particularly practical to bend, and will require many angled fittings to hook up. Soft copper, on the other hand, can be worked with hand tools. Typically coming in coils, you’ll need to straighten it out with something like a Kwix handheld pipe straightener. After you’ve straightened the piece, it can be bent with a handheld metal tube bender. Most good ones will have angle markers inscribed on them to make matching angles easy.
