If you can find a good welder they can be upgraded.
I did 4 Blichmann's for a local brewery.
I converted them to be the same in construction as the Morebeer conicals.
The bottom port was increased to 1 1/2"
The racking port was increased to 1"
I also built racking arms with an indicator for each of them.
I don't know what you said, but your wrong.
