Topic: LP inconsistent shots > RE: +Vetrano on the way (82 lines)

If your LP shot resistance is inconsistent sounds like PF build problem,
most likely in fill and distribution. Generally speaking Miss Silvia is
highly sensitive to poorly built PF loads so not too hopeful she will cure
your problem of inconsistent pulls. Since IIRC the machine you purchased had
the OPV adj down won't be as bad as stock, but the handle side of the PF is
usually the problem.
Might be helpful to review some of these referenced articles and threads:http://www.home-barista.com/forums/viewtopic.php?t41There are many different styles that work well for different people. Find
what works for you consistently and stick with it. Naked PF paramount tool
in diagnosing PF build problems. FWIW I fill to slightly heaping (from
grinds dispensed into SS canister which helps minimize clumping), very
lightly side tap the side of PF to settle grounds (don't tap the PF locking
tabs!), Stockfleths to distribute and level grinds, light level tamp, couple
light downward taps on counter to knock any stray grinds down, med mildly
nutating tamp to firm level tap ending in almost no pressure polish lifting
the tamper away.
Also, when working on your technique it's best to stick to one forgiving
blend at the same roast level each time (like Monkey) until you are
consistent with it. 
Filling by strictly weight only makes sense if pulling the same blend/roast
all the time. 7/14gr single/double PF loads are starting ballpark
parameters, not set in stone to always use every bean every machine. That
said with each different blend/SO your technique should yield about the same
weight PF build to build for that particular blend/SO. Once consistency
achieved then can play with up/down dosing and how it affects different
types of shots, types of beans etc.

	Grinder: Mazzer Mini
	Measure: I suppose by volume.  I just fill and tamp.
	
	Interesting thoughts.  Maybe I should measure by mass the coffee
going into the puck.

		Steve, what grinder are you using?  Do you measure the
grounds for each load?  Eliminating variables is the key to getting
consistency, which in turn should let you move toward the shots you
desire...

						Yep.  I'm rather excited
because I've not been having terribly good luck with my Pavoni.  No doubt
its a great machine, but I have having a heck of a time getting any amount
of consistency from it.  Sometimes there is no resistance, sometimes a ton.
I'm hoping Silvia will help me actually produce some good shots and in the
mean time teach me enough to use the Pavoni successfully.
