Focus stacking for macro

lotsa macro shooters here so i thought i'd ask the question, has anyone tried this technique ? if so did you have any success ? I'm a huge fan of Lord V on flickr and recently tried his focus stacking technique with terrible results. my PP skills are just not a match for this technique unfortunately. lol
