I don't rememberif this has been brought up before. I just noticed a post where someone couldn't remember how something went together after taking it apart to do repairs. Buy as cheap as you can find (if you don't already have one) digital camera. Take pictures of anything you are getting ready to take apart, remove or disassemble. Really a great idea if it is a major project. Take lots of pics. Close-ups and overall shots. Once you have the camera it doesn't cost a thing to take as many pics as you need too.
