Great Video! Did you create a reflux column? Would love to see a video on that. - Also when connecting the threaded sections would you use teflon tape?
I bought a tri-clamp dephlegmator section that I am using as a reflux condenser. I have been working on some ideas to make a less expensive version. No teflon tape is needed at the points where I have threaded connections (no leaks) except for the cooling water.
Most brewing supply stores (for home brewers)have them and some larger suppliers will sell to individuals as well. You can also find them on Amazon (search under triclamp). hope this was helpful
