Force carbonating with this setup using the TAP (vs a carbonator cab) worked great. I didn't really shake them, just rocked them back and force a few times and set the regulator at about 20psi. About 3 days later they were nicely carbed and I turned down to about 8psi for serving.
You would have to clean some silicone from the threads but you could definitely replace the new fitting with the original cartridge holder. I debated using pvc glue but that would have been permanent and I wanted to leave the option to use the cartridges.
Yeah those are the Tap a Draft (16g) taps. I have the cartridges but no calipers; sorry.
For the pressure relief hole I just used a dab of silicone worked into the hole.
Thanks, I like the labels much better than the Tap a Draft logo. Since I'm a printer/signmaker when I'm not drinking...
I did mine with 3/4" threaded pvc reducers, to 1/2" threaded to 3/8 quick connects. To get it leak free I just siliconed the threads of the 3/4" reducer and teflon taped the 1/2" threads in addition to silicone in the pressure relief valve.
The tank is a 20oz and the regulator is the $35...
