In answer to Chris, we made a wort chiller following the directions from an
article published in Zymurgy that we heard about in the Beer and Wine forum
on Compuserve. A rough summary of that article is as follows:

Go down to your friendly home handy-man supply center and buy the
following:15 to 20 feet of 3/8" o.d. coiled copper refridgerator tubing.
($20), 2- 3/4" pipe clamps ($.75 ea.), 1- 1/2" i.d. garden hose (50ft was
the shortest I could get, $8), and I'll assume you have 3/8" i.d. plastic
hose already. If not, you'll need about 2 inches of the stuff. Now, take
the 3/8" copper pipe and start to carefully bend it. Make a J type bend,
much like a racking tube, at one end. This will hook on to the side of your
boiling kettle. Then allow a straight length to any depth you might desire
(mine's about a foot). Then start to coil the pipe to fit inside a 5 gallon
pot. You can customize the size to your situation. After coiling, leave
enough pipe left to come back up to match the first J bend. Be careful
thoughout not to kink the pipe! When you are done, you should have
something that looks like the guts of a commercially available wort
chiller. The J type bends at the two ends allows it to hook on to the side
of a pot or bucket and keep the hard to sanitize garden hose completely out
of any possible contact with the wort. Now decide how much garden hose you
want on the end. I used 10 ft.Measure from the female fitting end and then
cut the hose there. Now take about and inch of 3/8" i.d. tubing and shove
it on to one of the ends of the copper pipe. This will act as a spacer to
interface with the garden hose. Now slide a hose clamp onto the hose and
then put the cut end of the hose over the 3/8" plastic hose spacer. The
1/2" i.d. garden hose should fit perfectly over the 3/8" plastic tubing on
the copper pipe. Simply tighten the hose clamp on the joint. Now cut
another 10 feet of hose and repeat on the discharge side of the wort
chiller. Voila you have a wort chiller. Now if you want, buy a new female
fitting for the 30 ft hose you have left over (about $1.50) and you also
have a perfectly good 30 foot garden hose! The female hose fitting works on
my kitchen sink. This contraption will bring 5 gallons of wort to pitching
temperature in about 20 min. The chiller is very easy to make (took me
about 20 min.).
