Article: Prior to cutting any wood, make sure you correctly measure the width of your window to ensure that you create a backplate of the appropriate dimensions. Don't measure the entire open space of the window, rather, measure from the first inner lip on the interior frame of the window. Do this to ensure that your built box overlaps the window frame, rather than falls through it. This flush (even edges) construction also makes sure that the window remains weather-sealed. Make sure your measurements account for any abutting vinyl ridges or channels within the window frame. Prior to using any power saws, ensure that your measurements are exact and that you are safe from any debris or wood chips. If your measurements are not exact, your entire box will be a waste of effort. Follow the old adage: measure twice, cut once. Mark your measurements on your plank of wood, drawing out lines that indicate the height and width of your backplate. Following the lines you marked, use your saw to cut your plank of wood down to a size that will fit perfectly in your window. Choose a track saw to ensure your line is as clean and straight as possible. If you do not have a track saw available, you can use a regular circular saw. Be aware that using a circular saw will be more difficult and result in a more uneven cut. Save the excess wood, because it is the same length as your backplate and can be used later. Wear safety goggles to protect your eyes from any flying wood particles. Measure the width and the height of the air conditioning unit to know how large of a hole you will need to cut in the backplate. Measure the width at its widest consistent point, not where the sides of the unit begin to curve in towards its face. Take any pieces jutting off of the unit into consideration to provide enough clearance. This will make sure the unit can pass through the opening of the box you will create. Take measurements of the flanges on the bottom and top, because your wood panels will need to incorporate two indented portions to accommodate the flanges and secure them in place. Pencil these measurement marks onto your backplate with a carpenter's square and straightedge to make sure you have lines to follow when cutting. Using the measurements you took from your AC unit and the widths of your boards, find the proper cutting dimensions for your wood. For example leave 3-1/4 inches at the top to catch the window and clear the flange, 11-3/8 for the height of the unit, and then 1-1/2 at the bottom for the lip. This makes a total of 16-1/8 inches for the weight of the cut hole. Add a little to ensure clearance, bumping up the cutting measurement to 16-1/2. Mark your wood with a pencil at 16-1/2 on both sides of the wood to align the track for the saw. Trace the lines where you will cut, along the straight edge, to ensure that you will cut at the proper places. Make sure your measurements are accurate, using a straight edge and carpenter's square to align the measurements on both sides of the wood. If you ever realize that you made a mistake in the measurements, be sure to erase your old lines to avoid following them with the saw. Drilling holes in the corners of where you want to cut out the center of your backplate allows the jigsaw blade to get started without cutting in from the side. You can't cut in from the side, because that would cut an entire piece off of the wood that you need. Insert your jigsaw into the first pilot hole and follow your traced line to cut out the box from your backplate. Hold the jigsaw steady to ensure a clean line. Jigsaws have a tendency to "walk", meaning they can start moving in other directions if you aren't careful. If you have a track saw, use that for a cleaner, more stable cut.
Question: What is a summary of what this article is about?
Measure the width of the window to know how wide your backplate should be. Double check your measurements to be safe before cutting. Cut your wood piece to fit the window. Measure the air conditioning unit. Add up your measurements and wood widths mathematically to ensure the correct dimensions for the box. Draw a diagram on your wood, of the hole that will accommodate your AC unit, to guide your cut. Drill holes in the corners of your diagram to accommodate the jigsaw blade. Cut out the center of the backplate, from pilot hole to pilot hole.

Problem: Article: Give each one a few passes under running water. Wash away any loose ash, resin, or other materials. Make the cleaning solution that you'll be using momentarily that much more effective by giving it less stuff to get rid of. You'll be bagging each individual piece in a moment, and then adding salt to each bag. However, keep in mind that the base is much bigger than rest, and simply adding salt after you bag won't ensure that any reaches the base's interior. So pour some into the base now before you bag it. Place each one in its own sealable, watertight plastic bag. Do not combine multiple pieces in one bag. You'll be shaking these up soon, so don't risk banging glass pieces together, since this will damage them. However: Fill the bag with enough rubbing alcohol to completely immerse the piece inside. Then add enough salt to cloud the liquid slightly. Err on the side of too little salt, rather than too much, since too much will result in clumps that may cause blockage in various pieces. 70 to 91% isopropyl alcohol is usually sufficient. However, extremely dirty pipes might require 100% acetone or nail polish remover. As an alternative, you can also try mouthwash, since its aftertaste is far more pleasant than any that might linger from rubbing alcohol or nail polish remover.
Summary: Rinse the pieces in the sink. Add salt to the base. Bag each piece individually. Add rubbing alcohol and salt to each bag.

In this chapter, you can find 2,000 SP in a coffin near where you talk about Simmons and Ada. There are also 5,000 SP in a coffin near the spike trap. Kill the zombies you encounter for extra SP. When you fall into the next area after pulling the levers, let the game save, then quit the level and repeat as needed. For extra SP, try shooting the zombies in the head to make them Bloodshots, which are worth more. These chapters have lots of enemies that drop high amounts of SP. Each Ogroman enemy (the giant-like creatures with red organs on their backs) drops 4,000 SP. There are two Ogroman enemies in 2-3 avoid using the third AA gun to be able to get the SP from the second Ogroman. In 2-4, there are several Napad enemies (the ones with hard armor shells you need to break) worth 1,500 SP each and several Strelat enemies (the lizards that spit spines at you) worth 1,000 SP each. Try using the grenade launcher to kill all the Napads in the foyer to get about 10,000 in a very short time. In this chapter, you're in a race against Chris. If you're quick, you can rack up tons of SP in a short amount of time. Beating Chris to the elevator nets you 2,000 SP. After, when you're hacking the locks, use the shotgun to take down the drones effectively. If you do well, you'll beat Chris and win 14,000 SP. After the Simmons cutscene, the game will save and you can repeat this process for more SP. A good deal of SP is scattered through the entire chapter. Napads are worth 1,500 SP each, while Whoppers (the enormous fat zombies) are worth 2,500 each and Shriekers (the zombies with the large red growth on their chests) are worth 1,000 each. There are also lots of SP drops distributed in the various boxes, including a 4,000 SP drop in the treasure chest after the first Napad. Level 2-3 is especially lucrative killing the enemies in the underground lab can earn you about 25,000 SP in less than ten minutes. Jake has one of the easiest opportunities to farm SP in the entire game. The shopping district part of Chapter 4 has no enemies and two boxes containing a total of 7,000 SP. This section can be run through very quickly, so if you're willing to repeat it over and over again, you can earn tons of SP in a short time.
