I welded it.
That's what I do.
What I haven't explained is that the reducing bushing is actually a 3/8" bushing welded to a 1/2" bushing with the barb end of the stone welded into the 1/2" threaded end of the bushing.
These are actually stainless hydraulic fittings.
I used surplus parts from work to make it work. Yeah yeah I know I "stole" but those fittings would have ended up in the garbage. The company I work for buys stuff and if they never end up using it never gets sent back and we rarely re-purpose material.
Being a fabricator and welder has made this hobby much more affordable.
It also helps when welding and fabricating for local breweries.
I really don't have a need to brew my own beer that often, or buy beer brewing equipment.
