Thanks for the lead Mike. I just got back from the store with all the bits to make the spout. I've tapped the first water jug and it looks like I didn't mess it up to badly. Easy peasy.
Cool and glad to hear. Technically the hole should be reamed or drilled a bit as the tap requires some force. I didn't have anything large enough so I went for it. The small sprinkler pipe section is a tight fit (not too bad actually) but this is good because it seals really well and mine doesn't drip at all. On my second lid I used vasoline to lube the tap and it left the threads a little cleaner than the lid I used nothing on.
