Bending copper pipe without any specialized tools can be difficult, but there are a few methods you can try:

  1. Manual bending - If the copper pipe is thin enough, you can try to manually bend it using your hands. This method requires a bit of strength and patience. Place the pipe between your hands and slowly apply pressure until it begins to bend. Be careful not to apply too much pressure, as this can cause the pipe to kink or break.

  2. Using a lever - You can use a long lever such as a metal pipe or a wooden dowel to bend the copper pipe. Place the lever on top of the pipe and apply downward pressure to the middle of the lever to bend the pipe.

  3. Using a bending spring - A bending spring is a flexible spring-like tool that can be inserted into the copper pipe to help guide it while bending. This tool can be helpful for creating smooth bends without kinking or damaging the pipe.

  4. Using a homemade bending jig - If you have access to some basic tools, you can create a simple bending jig by clamping the copper pipe in place and then using a piece of wood or metal to bend it to the desired angle.

Please note that bending copper pipe without proper tools can be challenging, and it's important to be cautious to avoid damaging the pipe or causing injury to yourself. If you're not comfortable with bending the pipe yourself, it may be best to seek the help of a professional plumber or metalworker.
