Well I had started the build before I found HD. Then added to the plans the more I read. Then I read the Flute talk thread yes and 3 times! 
I then decided to build a 4" flute. Again what was I thinking I know. I am still building the flute that will be another thread at a later time. But I have grown impatient and would like to get something going a little quicker. So I am falling back to the original plans. That I already started. Yes I know its not the norm. Yes I know the first design I will finish is not the optimum still to build. But it is what I have working and I want to finish it. With that being said here we go.The first phase of the build will be the CM head and column. I chose a 3" water jacket condenser 2" column CM still. Modeled after the Mile Hi stills. This will also later be used as part of the reflux condenser for the VM and LM heads by adding removable parts. I had a request to show how I made the 3" water jacket from Kentucky Shiner. So here it goes. I have a few pics to upload so bare with me till I get done please.
I first found a steel pipe that fit inside the 3" L copper pipe. It is 2 7/8" OD with around a 1/4" wall thickness. Its what I had? I found if I wrapped some electrical tape around it a couple times it fit nice and snug in the 3" pipe. I then rounded the edges so it would give me a nice round place to bend the pipe over. So the sharp edge wouldn't cut into the copper while hammering it over.
