Here is the new Nixon Stone still I designed with 2" copper. It is a modification of my previous still which controlled reflux ratio with a sensitive valve controlling the cooling through the reflux condenser. This one uses the same condenser, but ran to complete reflux, and the sensitive valve can now be replaced with an ordinary needle valve attached to the 'stream splitter'.
This picture shows my sketch and the reflux condenser jacket with a customized tip (hammer and saw):
Then I soldered on a threaded fitting to join it to the stream splitter:
This shows the connection of the reflux condenser with drip tip, to the stream splitter attachment. The overlap is about 1/4" so that all the condensed vapour goes into the stream splitter cup:
These two photos give you a view of the stream splitter before I soldered it into the 2" pipe:
The stems were cut down later to fit it in.
Here are the three peices and the column and boiler:
