Watch this video to learn how to use a framing square to figure out the plumb and set cuts for your rafters. You can purchase metal stops that clip onto your framing square so once you have the angle you can turn your framing square into a jig. This is handy if you have a number of rafter cuts to make. Make sure to use the inside or the outside of the square to mark your measurements.

This is how to install a window if you have exterior trim that is easy to remove around the window. If you have aluminum or vinyl siding, or a masonry exterior the process is more complex, because you can't simply remove the trim around the outside of the window. The process of plumbing and squaring the window are the same, but usually you can only shim the window from one side.

As you can see hanging a door is rather easy. The key is to make sure the door is plumb. In the video, the rough opening is square and plumb, and only a half inch wider than the door jamb. Of course this is the best case scenario. Often times, in older houses, the rough opening will be out of plumb and square. So, like the video shows, plumb the door by itself and don't fit the door to the rough opening.

I searched for a while, and this is the best video I could find on installing kitchen cabinets. It's a time lapse video of the installation so read through these pointers as you watch the video.
