i did my 1st and only cider that way too, using a juiceman junior from the 80's, just a few months ago. yes, you should be careful to clean it out every few lbs and keep it spinning at high speeds one apple at a time...
i had about 30lbs of apples and topped off what came out with about 2 gallons of fresh juice. there was a lot of juice leftover in the pulp, and i semi-cored them (just cut the seeds section out)... i think one of those simple presses using two flat boards and 2 "D "clamps would have been great to squeze the residue through for another gallon.
anyway, the cider is coming along nicely, and as for a lot of work, thats relative... we had 2 sets of hands and a few beers so time flew in my recollection
