In one sentence, describe what the following article is about: the wood until it is very smooth. Sand the entire surface with a hand sander or an electric sander to get rid of rough areas and imperfections. If your wood is pretty rough to start with, begin sanding with a rough sandpaper with a grit of 100 or 120. Progress from rougher grit to finer grit sandpapers, which allows you to reduce major irregularities before achieving a fine finish. To get a very smooth surface you should end with 400 grit sandpaper.  Even if your wood already feels pretty smooth, take the time to run 400-grit sandpaper over it before sealing it. This will ensure that the surface is completely smooth once the sealant is applied. Sand with the grain, which means that you need to follow the lines of the wood grain straight back and forth. This will help you avoid leaving behind swirly marks on the surface. Wipe the entire surface several times. This will help you avoid getting wood particles stuck in your sealant, which will create an imperfect surface.  A tac cloth is a special sticky cloth that is specially made to remove the dust from the surface of wood after sanding. Tac cloth will remove even fine particles that resist removal from a cloth. Avoid using water on unsealed wood, because it can alter the wood's grain and create roughness. the wood to change the color or to highlight the grain, if desired. Apply the stain before you apply your sealant so that it is able to soak into the surface. There are a variety of colors and types of stains available but most are applied with rags. First you will wipe your stain on the wood and then let it set for a specific amount of time, which is stated on the stain packaging. Then you will wipe off the excess with a clean, dry rag.  The container of your stain will tell you how long you need to wait after applying stain to apply a sealer. Wood stains are available at all hardware and home improvement stores. These products allow you to apply colorant and create a water-resistant surface at the same time. They are a quick-finish option if you have a large surface and not a lot of time to seal it.  For example, many people use this type of combo product with sealing a deck, due to the large surface area that needs to be treated. They are available at all hardware and home improvement stores. These products can typically be applied with a brush or a roller.
Summary: Sand Remove any sawdust from the surface with a dry rag or a tac cloth. Stain Use a stain and sealant combo to complete your project quickly.

Traditional dizis are made of bamboo, while historically, dizis and other flutes have been made from bone, jade or other stone, or pottery. Be sure to take into account being able to acquire and prepare the materials. Choose a piece of material that is about ¾” to 1” in diameter. Bamboo is the ideal material for a homemade dizi, as it is easy to acquire and easy to manufacture into a dizi. It is also lighter and will likely be easier to play, which is useful if you are a beginning player. Bamboo can come from a regular bamboo plant with any extraneous leaves removed, or you can repurpose another bamboo object, such as an old bamboo fishing rod. There are different strains of bamboo that can be used; purple bamboo is typically used in the northern regions of China, while white bamboo is typically used in southern China. The size of the flute will determine the musical key in which it plays. Flutes are typically available in the following keys (from longest to shortest): F, G, G#, A, A#, B, C, C#, D, D#, E, F and F#. A good length is approximately 18-20” long. Longer flutes may have an additional finger hole (the larger dizi has this), and they play lower octaves. Small flutes with higher octaves are smaller than 16”, while longer flutes are ideally 24-26” long. Choose ringed ends, capped ends, or no ends for the dizi. These will determine how long-lasting your flute is, as well as how susceptible to cracking or molding it may become. The materials for the capped or ringed ends, called ferrules, can be made of brass, bone, plastic or wood.  Ringed ends: Some flutes have a brass ring around the end. This helps the flute (especially those made of bamboo or other wood) from cracking. Moisture can get underneath the ring, however, and cause molding. These can also be installed on a flute that did not previously have a ring in order to stop a crack from getting bigger. Capped ends: These ends are often made from plastic, cow bone or horn. Flutes with capped ends typically make brighter tones. Moisture can get underneath the cap, however, and cause molding. No ends: You do not need to have any rings or caps on the end of your flute. Instead, you can paint the ends to add decoration, or you can leave them bare. However, bamboo flutes especially may be susceptible to cracking more easily than flutes with ringed or capped ends. Find the correct size of plastic or metal ring or cap to fit this diameter at a hardware store. If you are not using any ends, you can also opt to wrap string around the dizi to prevent cracking.

One-sentence summary -- Select the type of material for the dizi’s body. Choose the size of your flute. Determine the style of ends for the dizi. Carefully measure the outside diameter of your flute body.

Problem: Article: Meanwhile, prepare a baking dish by lightly coating the bottom and sides with nonstick cooking spray. If you have a large, heavy-bottomed, oven-proof skillet, you do not need to prepare a separate baking dish. The entire meal can be prepared in this oven-proof skillet. Add the oil to the skillet and heat over medium-high until it becomes notably smooth and glossy. This can take a minute or so. Mix the flour and salt in a large resealable plastic bag. Place the ingredients in the bag, zip closed, and shake quickly to distribute the salt evenly throughout the flour. Alternatively, you could combine the flour and salt in a wide bowl with shallow sides. Make sure that the bowl is shallow enough and wide enough for you to place a piece of steak in. Sift the ingredients together to ensure that they are well-combined. Add the steak to the flour and salt in the plastic bag and seal the bag closed. Give it a good shake so that all sides of the beef are coated in flour. If using a bowl instead of a bag, add the steak pieces to the seasoned flour in the bowl and turn them over a few times, dredging all the sides completely. Cover with aluminum foil and bake for 60 minutes in your preheated oven. Slow baking in liquid is another ideal cooking method for round steaks, which tend to be fairly lean and not very tender. The slow cooking process helps the meat break down more, and the liquid prevents the beef from drying out. Uncover the dish and sprinkle the beef with the cheese. Return it to the oven and bake for another 5 minutes, or until the cheese is completely melted. You could add more cheese than the recipe calls for, if desired, but adding more cheese may increase the amount of cooking time since a thicker layer will require more time to melt. Pull the finished steak out of the oven and transfer to individual serving plates. Spoon the vegetable mixture on top.
Summary:
Preheat the oven to 325 degrees Fahrenheit (163 degrees Celsius). Heat oil in a large skillet. Combine the flour and salt. Dredge the steak in the flour mixture. Bake until tender. Add and melt the cheese. Serve warm.
