Hi,
I have been working toward a more consistent espresso extraction and need some advice
to overcome problems with my results.
I have been trialling some of the guidance from videos, the Barista techniques book, and the website here. Also attended the Sunbeam course.
My equipment:
EM6910
EM480 grinder (calibrated with 4 washers and set on a grind of 9).
electronic jewelry scales (nice and small... $7 off ebay
).
standard double basket from coffeeparts.com as it fits my tamper better (sunbeams are too large)
Ezytamp (58mm)
Beans:
Di Bella Ali reserve (a nice bean if you have not tasted it!).
Whats wrong:
I measure 18g of ground coffee and tamp it in my basket using the eazytamp (15kg calibrated). It seems to be very low in relation to the basket rim. after tamping the tamper base is almost completely sunk into the basket.
On extraction the coffee is not swelling up into contact with the shower screen.
The puck appears quite muddy and does not break... just soppy and bends.
Extraction times seem ok and the pressure stat on extraction is in the top of the gold band on the dial. THe needle does seem to pulse up and down at times.... not sure what this indicates (I thought it might mean overdosing or too fine a grind).
Id appreciate some advice at any rate
. These baskets are designed for a 18g dose at the top end so I thought Id ask around before updosing and using more beans unnecessarilly. 
Cheers
