Making cider is easy:
• take some apples (variety really not that important) and mash them up. You can either use an apple scratter or a large bit of wood in a bucket and hit them lots until they are broken up into smaller pieces.
• wrap this juicy mess up in some net curtains (or if you're feeling posh, some muslin) and put it in a cider press (you can make your own for about £50 or buy one from eBay for a little bit more).
• press the apple pulp and collect the juice in a fermenting bucket.
• add some sulphites to kill off any bugs, then in a day or so add some yeast and sugar. More sugar = more alcohol.
• put the lid on and leave it somewhere warm to ferment
• after a couple of weeks when everything has calmed down, you need to rack the cider off and get rid of the sediment. The more times you do this, the clearer your cider will be.
• Finally, bottle it, or just drink it straight from the keg.
There are a few more specifics that you can pay attention to, but essentially that's all cider making is. Homebrew forums is a good place to look, with a cider specific section.
