In "Enoch and the Gorilla," one of Flannery O'Connor's blackly comic short stories which were set in the Deep South in the 1950s and were typically about rude awakenings in the lives of her characters, a guy named Enoch, who is sort of a simpleton, decides to set out on an adventure that will involve a dramatic change to his physical appearance. Enoch has been inspired by a truck that pulled into town with a loudspeaker advertising "Gonga, Giant Jungle Monarch". Boys and girls will be able to line up and shake the gorilla's hand later that day, for a dime. Enoch tells the waitress at the diner where he's a regular that he has big plans, and that she won't be seeing him much longer "like this" -- meaning as he looks now. The waitress stands there, one hand on her hip, the other holding up a pot of coffee. "Any
way I won't be seeing you," she replies, "is fine with me."
Now that anecdote does mention coffee, so it's not completely off-topic, though it was probably a Bunn burner. Not too many diners in small towns in the American South had lever machines in the 1950s.
Anyway, I had my own Enoch-like put-down this morning, after searching for several days for an adapter to connect the 1/4" NPT thread on the pressure gauge to the 25mm(?) metric thread on the Cremina's boiler neck. I find a company called AdaptAll in Ohio. If they don't have this coupling, nobody will. I tell the tech about my own big plans to connect a pressure gauge to the boiler neck of my Swiss-made espresso machine. He replies "Good luck!" I ask him, why? He says 25mm metric pipe fittings are rare; they're usually 24 or 26. I tell him that the exact measure of the thread is 24.7mm and ask him if that would be considered a 24mm or 25mm thread. "You can consider it anything you like."
