Installing a Tri-clamp Soldered Fitting to the Chapman Fermenter Lid

Recently I purchased a couple Chapman portless 7 gallon fermenting buckets to replace my traditional glass carboys.
I ferment in a BrewPi controlled chest freezer, so having ports on the bottom of my fermenter is not needed as I do transfers from the top of the vessel.
I have developed a CO2 pressure transfer system for my old glass carboys that I love and wanted to continue to use with my shiny new Chapman fermenters....
While that certainly could have been accomplished with a traditional bung it seemed too pedestrian for these fermenters.
Luckily for me I live 30 minutes from Bobby's BrewHardware.com shop. 

After a few minutes of discussion with Bobby, we configured a TriClover 2 attachment system.

One TC  for fermenting with my airlock & thermowell for the BrewPi probe
and a second TC to pressure transfer with CO2. At the heart of the system is the silver solder TC adapter.  
The hole on the Chapman lid was practically made for Bobby's silver solder 2inch tri-clover attachment... 
Once soldered on I have the ability to attach numerous adapters to the bucket.
I have pictured the two I am currently using...
First, the thermowell/airlock attachment gives me the ability to ferment and control temp from the single attachment.
Second, the pressure transfer attachment that allows me to transfer directly to my purger keg by using CO2.
While these are certainly nothing new for the home brew industry I think it is cool to show how to trick out your stainless fermenter.
All the parts are available from Bobby and the Chapman fermenters are just a fantastic vessel to work with.

    This is EXACTLY what i’ve been looking to do. Would you mind posting a parts list?

    I did the same thing a while back to my14 gallon and 2 – 7 gallon steeltanks. I also added a thermowell and corny gas in port to the lid. These work great.
