Ok you weiner dogs I finally got the itch to put one together. I really cannot say enough as to how easy it is to assemble. Just take your time and you'll do fine. I bought the Harbor Freight tap set and used a vise to hold the T joints and with the 3-in-1 motor oil, it did absolutely perfectly. Absolutely perfectly! No need for a drill press at all. Anyway I bought all the parts from Lowe's today and figured I'd give an itemized rundown of the parts and current prices. This is a Lowe's in West Virginia, parts purchased on August 13, 2017.
Granted I also purchased the 3-in-1 oil (2.99), lacquer thinner (8.38), red outdoor primer and paint (4.98) and black plasti-dip (5.98). I also bought a bottle of Deer Park sparkling raspberry and lime water and it was really bad (1.38).
I was really disappointed in the faucet handles. It appears Lowe's does not carry silcock handles seperately any more so they are essentially five bucks. In any case, I am sure you could get this stuff cheaper with multiple trips to multiple stores but I wanted to see if I could get it done in a single shot and I did. It is currently drying from what will probably be a crummy paint job but good enough to cover the black and protect against rust. Thanks to the creators of these plans for making it so easy.
