You can create a beautiful coffee table by simple stacking logs together. Line the logs end up and create a circle whatever size you need. Then just tie them all together with rope or twine to keep your coffee table secure. You do need to make sure that the logs are the same height and you may want to sand the tops down just a bit to make them smooth.
1: Table saw in place of a jointer. Any number of tips in previous issues address straightening edges of boards without a jointer. A jointer serves one purpose, but a tablesaw can serve many (just watch your local Craigslist for a decent one to come up.) The thickness planer is unavoidable, but until you can afford one, buy stock in the thickness you need.
