works a treat!
I managed to source a triple single floor basket but it had a rolled ridge on top and would not fit,
So I simply shimmed the plastic Group handle holder at the group head with 4 stainless steel washers to give slightly more space
First shot was pretty good, second shot had too much tamp and blew-out at the seal
Third shot was the goods! with less tamp and finer grind.
Too buzzed now to do any more shots, now I can do triple restrettos
photo shows single, double Krupps, then triple
Hey, just wondering how you managed to make the portafilter naked? =]
