Howdy all,
Im growing increasingly frustrated with the difficulty in locking on the portafilter on my NS Oscar. The portafilter with a loaded double seems to not lock in very far at all. With the blind, seems to lock in a bit further. I am getting some leaks with the double, no problems with the blind. Locking the portafilter in is a strain. Have to hold the machine on the bench.
Have recently replaced group gasket.
I thought maybe if I took a bit of brass off the lugs maybe that would allow the portafilter to lock in a bit further and maybe smoother?
I have a Giotto also, so have something to compare to. The difference is that the Giotto feels very metal on metal, wheras the Giotto is a smoth lock in. Should they be similar? I desparately want the Oscar portafilter to lock in more like the Giotto. Possible?
Any advice appreciated. Tim
