I'm no pastorbob but I've taken freewheels apart and rebuilt them - it's a bit tricky the first few times, mainly the reassembly. More often my 'quick and dirty' is to just flush with WD40, then ease in some Phil's as the primary lubricant followed by a dose of lighter oil to thin that a bit (Phil's seems to get a bit too viscous in colder weather). Works pretty well for me, but everyone has their preferred method.
