Sounds like this method would give you a wet and dirty arse and a chain that's too tight. Here's one that works, is no hassle and will get the chain the right tightness (hint: it should have a little bit of slack otherwise you'll trash your bearings). The only problem is that it needs a bit of practice. Push the wheel back so the chain is tightish, but not fully tight, and the wheel is slightly towards the non drive side. Tighten the non drive side nut. Push the wheel over towards the drive side so that it is straight and takes the chain to the right tension. Tighten drive side nut.
Job done and no sitting on the floor like a drunk schoolgirl after one too many breezers.
