In one sentence, describe what the following article is about: Every inch of fish needs a gallon of water and for each goldfish you add to the tank you should increase the size of the tank by 10 gallons (37.9L). Fancy goldfish can grow up to 20 inches (50.8cm), so by purchasing a 2030 gallon (75.7114L) tank you can avoid having to purchase another larger tank later as your goldfish grows and as you get more fish. Goldfish are not suited to live in bowls because they will outgrow them and they need a good filtration system. It is important to choose the right tank for your goldfish in order to make sure they have the best quality of life and to save you from having to buy more tanks later. If fancy goldfish do not have enough water they can get can diseases, be stunted in growth, and possibly die. Purchase gravel that is large enough that it won't get stuck in the goldfish's throat. Clean the gravel before putting it in the tank by rinsing it and then soaking it in water for a day. Avoid using soap to clean the gravel because it could harm the fish. Decorations also make the tank more visually appealing. When purchasing decorations for the tank, make sure to not get too many and make it too crowded. One large decoration and a few small ones is usually enough for one tank. Only put items in the tank that are meant for fish tanks. Do not put real coral or driftwood in the tank this can cause parasites. Rearrange the wood and plants on a monthly basis to offer the goldfish new areas to explore. Use real plants to improve the water, to create hiding spots for the goldfish, and to provide a food source. Plastic plants are easier to maintain and still offer places for fish to hide; however, they do not offer the same benefits as real plants. Fluorescent lights are the best choice for goldfish, but you can also use incandescent and halogen lights. Light helps goldfish keep a regular sleep cycle and makes sure that they maintain their color. Avoid putting the tank in direct sunlight -- this can cause temperature changes and algae growth. Having a filtration system keeps the tank and water clean as well as helps improve the health of the goldfish. There are different types of filters to choose from that serve different functions: Mechanical filtration (such as power, bow, sponge, and canister filters) is best for removing debris in water, like waste, food, and particles. The filter catches the debris and then returns clean water to the tank. Chemical filtration, activated carbon or zeolite, should be added to your filter to remove bad chemicals from the water. Biological filtration is a way to make the negative toxins in the water harmless. This can be done using an undergravel filter. The downside to this method is that it can take months to set up and develop into the tank. Plant filtration, putting plants and algae in the tank, is another way to make the harmful chemicals in the tank harmless. In order for this filtration to work you need many plants and fluorescent lighting in the tank. If you use tap water, you need to make sure to treat it with a water conditioning solution to de-chlorinate the water.Change the water in the fancy goldfish tank around once a week. Do not change all of the water at once, instead change only a third of the water each time. You may need to change the water more to keep the ammonia levels down. Test the water often to make sure the ammonia and nitrite levels are normal. The temperature of the water should not exceed 75 degrees Fahrenheit (24 degrees Celsius). During the winter, have the tank at 50-55 degrees Fahrenheit (10-13 degrees Celsius). If your home gets cold, especially at night, you can add an aquarium heater to the tank.
Summary: Choose a 20-30-gallon tank for your fancy goldfish. Choose large gravel that the fish can't swallow. Decorate the tank so the fish have places to hide. Put plants in the tank to help with water quality and filtration. Make sure your aquarium is well-lit for 8-12 hours a day. Get a filtration system to remove waste. Fill the tank with distilled or treated water. Change the water with the seasons.

In one sentence, describe what the following article is about: A small piece of plywood is a good choice for making a jig, but you can use any type of durable scrap wood that you have laying around. The piece should be about a foot long and about four inches wide. A 118 degree angle is ideal for drill bits, but you will need to create a 59 degree angle on your jig to get achieve this angle. Measure and mark your wood before you cut it. If you have a protractor attachment for your table saw, then you can just set it to a 59 degree angle and use this to cut a notch in the wood. Turn on your table saw and slide your piece of wood towards the blade so that it passes over it completely. You can use a guide piece to keep the wood straight and push it across the blade. Cut a V shape into the wood. This will keep your drill bit in place while you sharpen it. Wear safety goggles and keep your hands away from the saw blade. After you have created the slot in your wood, check it to make sure that it is large enough to fit your drill bit into. If it is not large enough, then you can cut it a little wider. Be careful not to make the slot too wide or it will not keep the drill bit in place.
Summary: Get a piece of scrap wood. Measure and mark it with a 59 degree angle. Cut a slot along the mark. Check the slot.
