Subject: Group Gasket
Need to replace my original Isomac Tea group gasket which im told is 8.5mm ,
the group handle has come loose a few times lately during a shot and has
sneezed coffee grounds. The handle has always locked at 7 o'clock. One on
line re-tailer says to buy a replacement 8.5mm gasket and another merchant
says handle should lock at 6 o'clock and to use a 8mm gasket.

Any advice on which size gasket to buy ?

Thanks, WS

Marshall...that works for me as well...the new screen I received as
replacement on my QuickMill Anita had a slighty more convex
shape...but not changing my routine has caused me no problems...in
fact, I've had more problems when I under-dosed

I have the same group. Either gasket should work. It doesn't matter
where the handle locks. Just stop wherever it seals. Pushing the
handle to some artificial "ideal" position will flatten out the gasket
and shorten its life.

Thanks Marshall, if i go to a 8mm vs a 8.5mm does that mean i have to use
slightly less coffee in the filter basket as it will fit higher into the
group head and the puck will hit the shower screen sooner than with a 8.5mm
?

Filling my LM double basket before tamping gives me 17-18 grams of
coffee. I've never considered whether the puck reached the screen or
not. I'd focus on filling the basket to your personal taste and forget
about the screen.

I normally overfill the basket as i get better pours that way, the puck
hits the screen a bit. So i was thinking that with a smaller gasket and not
sure how much difference the 8mm would make the overfilled filter basket
would now touch the screen before say a 8.5mm gasket would since the filter
basket fit deeper into the group.

The little bit extra coffee i overdose the basket with seems to make a
difference on
my E-61 i would think with less coffee due to smaller gasket the shot would
not be as rich.
