Chris,
 
I am going to have to order two extra Portafilters!  I have to give this a try.  I do have a concern however with some of the smaller machines that really need the mass of the portafilter to keep temp stablility for their shot.  Any thoughts?  I sure am glad I have an Expobar!

Those are wonderful pictures.  Crema in all its glory.  I'm going to 
have to look for an extra portafilter.

There has been some heated discussion about the reality of portafilter =
heating and temp stability and flavour.
Suffice it to say that people argue that it's possible that the =
portafilter may well have more value for temp stability in the *group* =
than the basket.
On an LM, we're seeing significant temp drop with the crotchless =
portafilter (it cools off far faster than with a normal portafilter) but =
the espresso doesn't exhibit sour or under-developed flavours.
Barry Jarrett repeatedly points out that the area of contact between a =
portafilter and a basket is quite small indeed.
It will be interesting to see what others find - especially on =
non-commercial equipment.

you can use a hole saw and a drill press and then round the edges with a
drum sander on the press. some people have used a cut off saw, others have
milled it...
there is at least one vendor selling pre-machined portafilters and offering
a modification service.

Chris,
Beautiful shot shots, especially the sequence. Your "thoughts" on it's value
as a training tool were excellent too.
PS I scrolled down and thoroughly enjoyed your 8/13 musings on "A 'Varietal'
Espresso Revolution: The Case for Single Origin Shots".

glad you liked it!

Chris:
Nice blog, great info. 
I especially liked the single origin shots. I use single 95% of the time.
Some get dumped right away but I have been blown away by others.

It's always seemed to me that the heat of a portafilter would not have that 
much effect of the heat of the extraction water since the water hits it 
(the PF) AFTER it has gone through the basket. I always thought that it's 
the temp of the water going through the coffee that matters.
It would seem that the temp of the grounds would have more of an effect 
than the PF body. Maybe, we should warm up the beans a bit....or leave them 
in the portafilter till they warm up ...
Does it matter at all how fast the drawn espresso cools off, other than 
whether a person likes his drink hot or cool?...I actually prefer my drinks 
at close to room temp...
Ciao,
Angelo

well... to me it seems that thr reason the portafilter has to me hot to 
temp is because the extraction it touching it..but since it is not 
there...move cup closer and there isnt much difference since the metal 
is not there...to me seems less is best...(less coffee being resisted 
by more medal anyway...

That is amazing.   Talk about the antithesis of black tar dribbles.  I am 
virtually speechless at just the beauty of it.

This is a multi-part message in MIME format.
I've been reading the messages on the "crotchless" PF.  I have the tools to
make the change to my PF but want to make sure I understand the
modification. 
The idea is to "cut off" the entire bottom portion of the unit, basically
setting it up to drip straight from he bottom of the grounds holder into the
shot glass/cup correct?

19) From: Pecan Jim Gundlach
Scott,
     Some people drill a hole the size of the filter down through the 
bottom of the filter.  When I did the portafilter for the La Pavoni I 
just cut the bottom off from the side with the Dremel.  I did not do it =
this way because I thought it was better, but because it was easier 
with the tool I had.

  I chopped mine with a Dremel, too, but I cut around the
bottom. Maybe that's why it took 5 cutting blades... Anyhow, I
love the way it works now, much more crema, and so fun to watch
the pour.
