Parts:
Remove the pressure release valve:
Drill out the hole to 1/2 inch:
Thread the coupler into the union. Add a steel washer followed by a rubber washer:
Insert into the top of lid:
Insert a rubber followed by a steel washer. Secure and tighten with a 1/2 nut.
Took the female end of the coupler and added a valve to it. This will allow you to turn the off the blow-off after the beer is done and pump in CO2 pressure in order to transfer the beer to a clean corny under CO2.
The lid must be placed on the keg first, then the valve connected. If the valve is connected before, the lid will not be able to be inserted in the keg.
Pressure was added and the rig was tested for leaks with soapy water via a spay bottle.
There is enough clearance in the end of the valve, it can be turned all around the keg and placed in any position.
A dip tube was attached and a 2L soda bottle was added. This way the blow-off collection container will be attached to the keg.
I think I will brew tomorrow and give this a try.

. I may have filled them a bit much, but I just HATE wasting wort.
