You'll install the hinges the same way you did for the first panel. This time, leave off one of the hinges for now. Every time you install a new panel, leave the hinge on that same side off until you've set the panel in place. Leaving off the third hinge makes getting the panel into the track a lot easier. Have a friend help you carry the next door panel and hold it in place on top of the first one. Adjust the panels so their edges line up perfectly. Hold the top part of the hinge up against the second panel to see where it'll rest. It helps to drill a hole for the lag screw first. Once that's done, fasten the hinge directly to the panel using the drilled hole and a screw. This will be the third hinge that you left off the far side of the door earlier. Place the roller into the hinge first. Fit the wheel into the track on that side, then screw the hinge in place. Look over the track to make sure it's parallel to the door, then screw the track's brackets directly into the door frame. Slide the track out so that it isn't touching the door frame, then tighten the bolts on both tracks to hold them in place. You'll need someone to climb up on a ladder to help lift the horizontal track. It'll have a small curved section that fits on top of the vertical track. Line up the sections. Place the bolts into the curved track section and tighten them to fasten the track sections together. Make sure the bolt threads are to the inside of the track. You'll need to then secure the loose end of the horizontal track section to a perforated angle iron hanging from the ceiling. If your garage does not already have an angle iron, find one at the hardware store and bolt it to the ceiling. Attach them to the other panels and tracks the same way you did before. When you reach the last panel, which reaches the horizontal track, stop. Don't place hinges or wheels on top of the panel. You can't install the last panel without installing the track first, since the panel will fall in on you. The last hinges should be placed partway down the door panel. Line them up with curved part of the track. Get the wheels on the track first before fastening the hinges with your electric screwdriver.

One-sentence summary -- Attach hinges on top of the second door panel. Stack the second door panel on top of the first one. Secure the hinges to the second panel. Fit the remaining hinge and roller onto the panel. Fasten the second track on the other side of the door. Connect the horizontal track sections to the vertical tracks. Bolt the track sections in place. Set the other door panels in place. Align the top hinges and rollers with the curving rack.

If you don't agree with what everyone else is saying, speak up. Maybe you don't like the way everyone is making fun of someone, or maybe you have a political opinion different from a friend's. It's ok if you happen to agree with everyone else, but if not, don't be afraid to speak up. Just make sure you do so respectfully. For example, if everyone loves eating at a certain restaurant, but you don't like the food, simply say, "It's not my favorite." How do you naturally speak when you're talking to yourself? That's how you should talk to everyone else. Don't dumb yourself down around some people and try to sound smarter around others. Use words you're comfortable with rather than slang terms you don't like or long words you don't understand. If you like using slang or impressive vocabulary words, that's ok too. Just be sure you're speaking that way for yourself though, not to sound like someone else. If you lie about how you feel, you aren't letting people know who you really are. Focus less on what someone's reaction will be, and think about how this will help someone understand you better. For example, if someone asks you to go dancing, and that's something you don't enjoy doing, tell them that. Then offer to do something else with them so they don't take it personally.

Position the log horizontally in the carriage so that the blade can cut through its center. Slide the log down the carriage until one end is flush with the blade. Cut the log in half lengthwise, then turn the saw off. To maximize the amount of lumber you get from the log, you can now cut several wide boards from the bottom of one of the halves you just cut. Once you've cut the log in half, line one of the halves up along the blade. You will need to stand it up on its edge. Turn the saw back on and cut the half into 2 equal parts. Turn the saw off and remove these parts. If you haven't cut boards from the other half already, place the remaining half log back in the saw carriage, turn the saw on, and cut this log into 2 equal parts. Always double-check that the saw is turned off when removing cut logs from the carriage to minimize your risk of injury. Place a quartered section on the saw carriage. Orient the saw blade near the open face so that you can cut a board off of it of a predetermined thickness. Turn the saw on and saw off a board. For example, if you want boards that are 1in (2.5cm) thick, align the blade 1in (2.5cm) away from one side of the log. Slide the quarter back under the blade so that the blade is positioned to cut a board of the same thickness as the first, and then saw off another board. Repeat this last step until you have cut the log into as many boards as possible. Remember to turn the log 90 before sawing off each board. Use your quarter-sawn boards to build beautiful wood products! For example, you might build a cabinet or table, use long boards for flooring, or create small objects like boxes or cutting boards. Place 2 quarters next to each other. Then slide each quarter under the blade and cut the 2 quarters at the same time. Remove the 2 resulting boards. Pull the 2 quarters apart and rotate each quarter 90. Place the quarters back under the blade, then cut another 2 boards. Repeat this process until you have cut all of the boards you can from the quarters. Freshly sawn wood typically has quite a bit of moisture in it, so your boards will need to be dried before you can use them. Find a storage spot outdoors where you can stack your boards away from trees (which can drop leaf litter and twigs) or soggy soil. To create the best air flow, elevate your boards on cinder blocks and line them up side by side. If you have a lot of boards, stack them in layers separated by thin wooden slats, then weigh the whole stack down with more cinder blocks. Look for a spot where prevailing winds will blow through the side of the stack of lumber. Use a moisture meter to check the moisture content of the wood periodically. The goal is to achieve a moisture level of around 15-20%. Depending on the weather conditions and the original moisture content of the boards, it may take several months for the lumber to dry.
