If you're going to use chains, might I suggest covering the lengths of chain with old inner tubes to protect the frameset. I personally use cargo tie downs from Harbor Freight. Nylon straps, adjustable length, and vinyl covered hooks at both ends. About $5 per set on sale. They make great portable temporary bike work lifts. Suspending a bike from above with rope/straps/hooks, is an age old tradition used by many and even old shops. So, if you only think dusting a bike is all you can do, then your experience or skill set is limited. I've worked on BBs, installed headsets, trued some wheels, and built up whole bikes this way. There are some useful ideas posted here, and home made stands in another thread. If you don't have plans for a work stand in the near future, then any alternative to help work on your bikes that much better is worth doing. Some folks have hung their trunk or spare tire-mounted bike carrier to a post, as a work stand. I personally created a ceiling mounted work 'stand' from 1" conduit and brackets. Floor space is a premium for me in my garage, and can't justify a traditional stand.
