Looks good..
I like the shotgun configuration, even a vent before the parrot is taken care of.
That thing could also knock down the vapor from a 3" column...with ease.
Yep, you still need a short spool tube, for the RC...8-10 " would be enough, though.
If you are going with an RC out of gas line, fine...if not..here is how I made my RC coils:

Both will work with a 2" column.
As you see, it doesn't take a long and expensive coil to get the job done on such a relatively small still.
If you pay attention to the ruler I laid at the side of the single wound coil, you'll see it's around 150 mm.
With a slow and steady water flow through it, it's more than adequate for a 2" VM/CCVM setup.
A lot of new distillers wind single, or even double coils with a length in excess of 300 mm, which ain't necessary to provide sufficient cooling to the vapors (on a similar 2" setup).
The purpose of the RC is to cool the vapors down, so a phase change can occur...not to cool the entire top of the column (not desirable for a number of issues).
As long as the RC can absorb energy from the vapor so it gets below 78C, you are golden...at this point it will condense and fall back into the column as a liquid (reflux).
I'm not overly concerned about the temperature of my RC, I just want to keep it below 60 C.
That being said, I don't run a traditional setup where the RC is feed from the exit of the PC. I have two pumps and separate reservoirs for the cooling water.
It allows me to run the RC pretty hot, without sacrificing efficiency on my PC. The small reservoir for my RC also gives me the option of a quick exchange of water.
