Your right sniff, I posted up on HB becaues of all the lusso owners there, but not one reply. 🙁 It was a bit disappointing really, first post and a dedicated lever forum too. Makes you value the Crema forums where at least someone will post to help you out or offer up ideas. I found the same OE photo and it seems they do just push in. I was trying to figure out how to get them out without damaging the plastic bits, but I suppose for the $10US from OE I might as well just drill a hole. They do seem to be a tight fit. When I next see AM I'm hoping to have a chat about them with him. 🙂 The handles are excellent but steam/hw taps would just complete it. I do realise it might be quite hard for AM to do them though especially because they are small and the grain/strength might be an issue. Still worth a try though. The only minor issue I've had is that the handles come loose a little easier, probbaly because they are metal inserts rather than the stock plastic. I was thinking of just putting a few wraps of plumbers tape around the thread to give it a bit of grip.
