Topic: A crotchless question.... (8 msgs / 160 lines)
1) From: Angelo
Well, boys and girls I finally sacrificed my Silvia PF. I've only made two 
shots and they really do taste better. I hope it's not the power of 
suggestion, but i guess if that's the reason, it's still ok.
Now, my question: In both pulls the initial flush of espresso came out in a 
number of streams (1st was two; 2nd was 4). They immediately (1/2 second) 
united into a perfect steady stream. Does this indicate channeling or 
merely the water reaching the bottom of the basket at different points at 
the same time and then flowing to the lowest point in the basket? I would 
assume that if there were channels they wouldn't close up that quickly....
One thing I noticed was that the stream dropped straight down from the 
center of the basket, like the stream from a faucet. I guess without the 
spout, I won't see my beloved coda di topo (tail of the mouse), anymore  :-(
Or, will I...?
Ciao,
Angelo

Angelo...     Yes, it's just the flow to the bottom of the basket.  The
channeling shoots out at obtuse angles in a stream like a high pressure
squirtgun.

Thanks, Rob... I guess I'm better than I thought :-)

Angelo you must be better then me, I've tried several different tamping
methods and have never pulled a shot with out at least one channeling
squirt. Mine will start out like you described and about 1/2 way thru the
shot a little jet or 2 will start. I'm using a LM triple basket. and a Thor
convex bottom tamper. I level off 21 grams and do the nsew roll and then a
straight tamp 30 lbs I just can't seem to eliminate the channeling.
I have a flat bottom Thor tamper comming. I must not be compacting the puck
even I guess, well I just need to keep practicing and trying different
techniques.

Ron,
I don't know if it helps the channeling, but I set my basket in a PVC 
reducing connection. It goes from 4" to 2 1/2. I never liked tamping while 
the basket is in the PF. This gives a broader base upon which to lean...You 
can get these at Home Depot. Bring your basket for sizing..
Let us know if you get better results this way.
Ciao,
Angelo

Ron,
    Try a slightly finer grind and a slightly lighter tamp.  I'm still 
just using a double basket and I haven't had the spider web size jet 
since the second try on the Silvia with the crotchless.

No, now you have the cone of burnished flowing meringue, the mouse's big 
brother. Or maybe coda brunita del wombat (tail of the burnished wombat)
