Article: Use the handle to open the jaws of the tubing cutter. Set the copper pipe into the jaws where you'd like to make the cut. Spin the handle to tighten the jaws firmly against the pipe. The tubing cutter acts like a vise to hold the pipe to the blade that's in the tool. Hold the pipe with one hand and use your other hand to rotate the handle around the pipe once or twice. You should see a faint line around the pipe that was made by the blade cutting lightly into the pipe. This line will be a guide as you cut into the pipe. Continue to rotate the handle of the tool around the pipe so the blade keeps cutting into the pipe. Watch the blade to ensure that it's cutting into the same line and not spiraling down the pipe. Use the small knob on the base of the tool to tighten the cutter as you go. This will keep the blade on the same track. Loosen the tubing cutter and set it aside. You should be able to hold both ends of the pipe with the cut in the center. Bend the pipe to snap the cut portion away. You should see a clean cut with no metal filings or debris. If the pipe doesn't easily snap off, use the tubing cutter to make a clean cut through the pipe.

Secure the tubing cutter to the pipe. Score the pipe lightly. Turn and tighten the cutter. Remove the cutter and pull away the pipe.
Article: at least 10 minutes every day. While meditation can help you gain enlightenment, you’ll need to do it on a regular basis. Luckily, you don’t need any special tools or massive amounts of time to mediate. You can sit or walk in meditation wherever you are. Just focus on your breath. Initially, set a goal of doing 5-10 minutes of meditation a day. Over time, you can expand the length of your meditations if you desire. Sit in a calm, quiet environment with your legs crossed or in a comfortable position. Close your eyes and notice how your body feels. Then, focus on the sensation of your breath. When your mind wanders, return your thoughts to your breath as soon as you notice. Don’t judge yourself for letting your mind wander, as it’s a normal part of meditation. A walking meditation changes the way you think. You can either wander or walk in an established path. As you walk, thoughts will come into your mind. Let them pass without judgement or holding onto them. This allows enlightened thoughts to enter your mind and raise your awareness.  Don’t try to think about anything in particular. Just let your thoughts come and go. You might also focus on your breath or on your footsteps to help you calm your mind, if it’s racing. You may prefer a guided meditation, depending on your experience level and goals. Fortunately, you can find many options online or through the app store. Experiment with different meditations until you find one that works for you. For example, Headspace, Calm, and Insight Timer are all meditation apps that offer a free version. Although you can meditate on your own at home, you may prefer to work with a teacher. You can find one by searching for classes in your area or looking for a local meditation center. As another option, you might go to your local buddhist temple or community center.  You may be able to take classes online. Additionally, check sites like Meetup.com or Facebook.com for meditation groups that meet in your area.
