Atomic 2nd Red Knob was created by Timmacx
Having just purchased an Atomic Brevetti Robbiati Cappucino Expresso Maker, and now enjoying wonderful cappacinnos that it produces, I have one query, excuse my ignorance, but what is the brass bar with red knob that slides completely out of the coffee holder and restricts the out-flowing brew for exactly?

I suspect that if left in place the whole caboodle would be prone to exploding!

Hi there Timmacx!

This brass dowel with a slight taper was suggested to Giordanno Robbiati, the inventor of the ATOMIC, by Thomas Cara of San Fransisco. It is of dubious use. I suspect that Cara, who also distributed other coffee machines, was impressed by the new espresso machines coming out at about this time. He also added a steam pressure gauge to many Atomics that he sold. Perhaps to entice customers in buying them. That brass rod, once inserted is very hard to remove when the machine cools down. It interferes with the use of the frothing knob and some models have that brass "stopper" with a kink in it. The biggest reseller of ATOMICS, Bon Trading in Australia, never wanted these and refused to carry them. Irene, the owner, who still kicks a.. reported to me a debate in Giordanno's Milan home concerning this. It happened in his living room underneath an original painting by Renoir! You don't need it, the swollen coffee grinds gives enough pressure. Check out the film that's here somewhere. As for exploding....rest in peace, you have a pressure release valve in the big bad black knob. Just where you want it: at your fingertips. The only design flaw that I see after owning ATOMICS for the past 35 years. Of course, if you leave that knob on, the threads get worn down some and at one point the whole knob assembly becomes a safety valve. Hey, c'est la vie! Handshake, FrEdErIcK

I think that this the steam enhancing device.

Do not use it!

Come on Colin...the ATOMIC cannot explode!
You can use that brass stopper...for something...don't know exactly what...the only use I have found for it is a dandy support for that spare red ball! Frittibaldi.

Thank you, fREdeRicK, for helping me make up my mind to wait for Otto.

Cawfee, hoping Otto is real and not just a figment of someone's imagination
