I do this on a slightly larger scale - I use about 50Kg apples typically and put them all through my shredder (bought for this purpose). i then press all the pulp (can't remember the term for that) and leave the juice in a fermenter for a month or so. then i rack off and leave it until the new year. so far i havn't bothered adding any yeast - the wild stuff does the job fine.
This year I will use a massive starter of specialised cider yeast though, they can battle it out with the wild boys as i won't bother putting any campdens in there...
i'm also going to have a few more apples this year
