Much easier than this.
For my mtb and cx bikes I have used gorilla tape from Halfords, stans valves, stans sealant, and a home made air blaster with track pump. I have found 2 layers of tape to be perfect but probably dependent on rim. Make a very small hole at the valve hole and really squeeze the valve in.
Home made air blaster is like the one on bikeradar: http://www.bikeradar.com/mtb/gear/article/how-to-make-a-tubeless-inflator-44290/

They are about a mile from me as I discovered yesterday. You'll need a tubeless rim, appropriate valves, rim tape and sealant. Possibly a tubeless pump or compressor.
