Problem: Article: Loosen the strings with the tuning keys at the end of the guitar neck so they don't have any more tension. Use a string cutter to slice through the strings near the first fret so they come loose and are easy to remove. Unscrew the cover on the back of the guitar's body to expose the strings and springs so you can pull the ends of the strings out. Then, use a pair of needle-nose pliers to pull the other pieces of guitar string out from the tuning keys. Be careful not to scratch the body of the guitar when you cut the strings since they may be sharp. Don't cut your strings while they still have tension or else they may spring back and hurt you. Look for the metal backplate attached to the back of the guitar's body where it meets the neck. Use a screwdriver to loosen the screws on the backplate to remove them. Once you take the screws out from the backplate, the old neck will pull out from the pocket easily. If you aren't able to remove the screws with your screwdriver, use a drill with a screwdriver bit instead. Be careful not to strip the screws since you need to use them again. Make sure you get a neck that's compatible with your type of guitar or else it may not fit into the pocket. Push the new neck into the pocket on the guitar's body until it fits tightly. Line up the center of the neck with the middle of the body and adjust it until the neck is flush. When you have the guitar neck in position, use a C-clamp to secure it to the body so it doesn't shift. You can get a new neck for your electric guitar from music supply shops or directly from the manufacturer. Make sure your clamp doesn't cover the area where you need to reinstall the backplate. through the back of the neck using the backplate holes as guides. Most new guitar necks don't have holes drilled in them, so you need to make your own holes. Use a drill bit with a diameter that's 18 inch (0.32cm) smaller than your screws. Put the end of the drill bit into the screw holes on the back of the guitar's body and push the drill straight down into the neck. Blow the excess sawdust out of the hole so it's clean, and repeat the process for the other 3 holes. If you want to ensure the holes are straight when you make them, you can also use a drill press if you have access to one. Set the backplate against the body of the guitar, ensuring that the holes all line up with one another. Feed the screws into the holes and use a screwdriver to tighten them. Tighten the screws in the opposite corners of your backplate so it applies pressure to the neck evenly. Continue turning the screws until they're flush with the backplate and hold the neck in place. After you secure the backplate to the neck, you can restring your guitar so you can play.
Summary: Take the strings off of your guitar. Unscrew the backplate from the guitar neck to remove it. Dry-fit the new neck into place and clamp it in place. Drill Reattach the backplate and the screws on the back of the guitar.

Problem: Article: Use a light touch when holding or moving your bubbler to avoid an accident. This is especially important for pipes made from materials like glass and ceramic, which have a tendency to scratch and may shatter completely if dropped or mishandled. Repairing or replacing a pipe can be expensive, so the best way to deal with accidents is by preventing them altogether. Set your pipe on a small pad or coaster when it's not in use so that it doesn't come into contact with hard surfaces. Store your pipe somewhere where it won't be in danger of falling or getting stepped or sat on. Consider investing in a protective sheath or hard-shelled storage case if you smoke frequently or plan on doing any traveling with a breakable pipe. The inside of your pipe is warm and moist, making it an ideal breeding ground for bacteria. Clean and disinfect your pipe regularly to fight off mold growth. Otherwise, you could be looking at slimy, discolored residue, foul odors and a generally unpleasant smoking experience. Refilling your pipe with fresh water every time you use it will help create a less hospitable environment for bacteria and mold. There's no good way to remove stuck-on mold other than by scrubbing it, which can be tricky if you have a small or oddly-shaped pipe. Over time, ordinary tap water can leave unsightly mineral deposits on the walls of your pipe. These deposits may also contain traces of chemicals like chlorine and fluoride, which you definitely don't want anywhere near your lungs. By using filtered or distilled water, you can eliminate harmful contaminates from your pipe while also enjoying a purer, smoother smoke. For best results, you should also rinse your pipe with purified water after cleaning. Keep a pitcher of filtered water on hand so that you'll always have a ready supply when it comes time to refill your pipe.
Summary: Handle your pipe carefully. Keep mold from moving in. Prevent hard water stains.

Problem: Article: The sides of a triangle are traditionally marked with three consecutive letters, usually A, B and C. The order that you choose to mark the sides generally does not matter, unless something in the problem you are working on specifies it. Mark the three angles of the triangle with letters that correspond to the side lengths. For example, if you use capital letters A, B and C for the sides, then mark the angles with lower case letters a, b and c. You can also use lower case Greek letters ,,and{\displaystyle lpha ,eta ,{ ext{and }}\gamma }. Place these so they correspond with the labeled sides, so angle {\displaystyle lpha } is opposite side A, angle {\displaystyle eta } is opposite side B, and angle {\displaystyle \gamma } is opposite side C. One way to determine that a side is "opposite" a chosen angle is to make sure that it does not form one of the rays of the angle. If labeled correctly, angle {\displaystyle lpha } wll be formed by the two sides B and C. It will therefore be "opposite" side A. Similarly, angle {\displaystyle eta } is formed by sides A and C and is opposite side B. Angle {\displaystyle \gamma } is formed by sides A and B and is opposite side C. Some math texts will use capital letters for the sides and lower case for the angles. Others do the opposite. It does not matter, as long as you are consistent. In your problem, you must be given some side and angle measurements. You should mark these on your sketch of the triangle. You may be able to calculate one or more measurements using some rules of geometry. For example, if you are told that the triangle is isosceles, then you are able to mark that two of the angles are equal, as well as the two corresponding sides. As another example, if you are told that two angles are 40 and 75 degrees, you can then calculate the third angle to be 65 degrees, since all three angles must add up to 180 degrees.
Summary:
Mark the sides. Mark the angles. Label any measurements that you know.
