Yeah, However I got it from youtube. Some guy was making a moonshine still. I used his design and refined it a bit.
Here is the link: http://youtu.be/viaizr5GVdg to the original video I got the idea from.
The way I refined the design was to get a some copper pipe fittings that allowed me to connect the coiled copper pipe to the pressure cooker using a threaded connector thus allowing me to use a stainless steel nut on the interior of the pressure cooker eliminating the threat of lead contaminates yet providing a much more stable connection than the "cork" method provides.
Further I use a threaded water tap/faucet on the opposite end of the tube and another threaded connector and mounted it via a hole I drilled in the plastic bucket. This allows me to fill the sump with water instead of ice and eliminate the "sump water" leaking out around the copper tube sticking out the unsealed hole in the bucket. (you don't need ice in the sump to distill water wherein apparently the colder temps are desired when distilling alcohol)
(note the thermometer connection also. Such is not needed for water distillation but I did not know that when I made this one. All further models I made don't have one.)
See the basic idea is to turn the water into steam and then cool the steam back down so it changes back to water.
I used about 20 feet total of copper piping.
