I have made one of these with nipples and I'm making one with cups. Ms Jellybean asked for help making one so I took pictures... a lot of pictures! This is by no means the only way to make these, I'm sure others have found cheaper or easier or different ways of making them. This is how I made mine, they have worked well and don't leak for me. I've made three now and had no problems with any of them so far (not long admittedly). I used push in nipples at first as I found they leaked around the holes and washers and I didn't want to futz with silicone etc so I decided to buy the more expensive screw fitting T pieces which I prefer and are easy and don't require drilling or fiddly bits. I bought my cups and PVC fittings from this seller on ebay http://www.ebay.com/itm/281169299671?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 I did not look too hard or bargain shop. I am a little lazy and this seller had what I wanted. I bought from them before and was happy with the product and service. I have one cup/nipple for every two chickens because mine are spoiled. YMMV. They all want to drink at once, usually two to a nipple so it is working for us. I went to Home Desperate and bought 1 99c piece of 1/2" pipe (they have small pieces) One of these -- it is threaded on one end and not threaded the other end "female adapter" One of these (not threaded) "cap" one of these "nylon hose barb for 3/8" pipe" (actually DH bought it, I bought the wrong one so he offered to go back for me <3) -- I think it was $2.38 Check it fits into the thing in the first photo labelled 46c -- I didn't! a length of 3/8" tubing (you can actually do this any size, but I wanted tube that would fit snugly through 1/2" hardware cloth and stay put) -- length up to you! Buy a bit more than you think you need. Check the nylon hose base elbow fits snugly onto the tubing, it should take a little bit of effort. A bucket. Many people use a 5 gallon, that is too big for us, I think mine is a 2 gallon. A dark colour discourages algae but it is harder to see when it gets grungy and it heats up quicker in the sun. I like one with a handle so I can clip it to our fence. Optional and expensive -- bulkhead fitting. I got mine from a local hardware store... Home depot had something similar. For $11 ouch! You also need a converter to screw onto that with a hose bib fitting on the other end that will fit your tubing. Ask the nice people in the aprons to help if you don't know what to buy. That is what I did the first time. You might find the bulkhead fitting on ebay...? (ETA: Ocap says you can buy them on Amazon and I did find a long list of them there. You can also buy them at aquaponics shops if you have one locally. If you are in San Diego go to Marshalls off Miramar Road, they are incredibly helpful and will help you find everything you need for this. You will also need a hacksaw or pipe cutter and PVC pipe cement -- preferably one that is for potable water -- I used some we already had. and PTFE tape -- optional but it helps stop leaks. You can use silicone instead if you want but I like the PFTE tape because you can undo it and change things around whereas silicone just gums everything up... plus the tape is cheaper.
