I was really proud of my steam tip \"repair/modification\" - until it failed. So now I wonder, what's missing from the equation.
Recently found myself between machines: gave away my Silvia to a sweet lady who dearly appreciated it, but I'm not yet brave enough to purchase the Celini that I covet.
So I dusted off my older Elektra Nivola, but noticed that the steam tip (plastic) had broken into pieces. I fashioned a way to attach, to the steam wand, a 4 hole metal steam tip (supposedly superior) I had picked up mistakenly believing it would fit onto my silvia.
The short of it is that the new configuration does not froth milk at all, no matter how I skim and position things. There is lots of action and fury - and the milk gets to temperature in a grand hurry.
So I'm thinking maybe I need a narrower, restricted, one hole steam tip, and that the whole steam/frothing action depends on the tip itself being the correct fit for the diameter and length of steam wand (which must affect the velocity/volume of the steam.)
