Subject: adding gliceur to LM Linea for pre-infusion - need help
I'd like to add a .6mm gliceur to one or two of the groups on my LM
linea.

I contacted espressoparts and bought the .6mm giggler they have for
sale.

Terry Z was very helpful and offered advice, but I'm afraid I
couldn't figure out how to install it.

my apologies to terry for not calling you directly - but as it was
some time ago that we talked and i just now got around to trying it -
I thought I'd open the question up to the group.

I've posted some pictures at http://picasaweb.google.com/wisdomcoffee/LMLineaGroupPictures

The last picture is of the 4 valves I bought from Terry. I think the
idea is to screw one of these little valves into one of the fittings
in the 1st picture. Perhaps on more recent LMs, there is a way to do
that, but on this machine, a good ten years old, I don't see a way to
do that.

I found a product on www.mcmaster.com that seems to be more like it,
the Orifices with Pipe Threads. like this part number 2712T46

However, they are NPT threads and I'm pretty sure all threads on the
LM are straight threads, not tapered (probably BSPP)

So - what do you think? can the valves I have be used in some
fashion? or is there another valve available that I should buy in
order to slow down the flow of water to my group head?

Cheers!

I see what you mean Paul - the hole into the copper fitting seems like
it is just the right width to tap the threads into. and the hex head
can extend into the fitting attached to the left side of the group.

all I need to do is get a tap that matches the threads of the valves -
Barry's offer not-withstanding, i'd feel better using my own tools -
i've broken taps before! - so i'll be looking for the right tap in the
next day or two.

thanks for the help all - I'll post pictures of the finished project
soon i hope!

Matt

It goes into the end of the copper pipe and brazed fitting that is
indicated by the first arrow. By first arrow I mean following the
flow from group > flowmeter. You tap the actual copper pipe/fitting
and screw it in. The hex head of the restrictor should fit inside the
1/4" fitting that is screwed into the group (your label "left side
from front"). If the hex head doesn't fit inside then don't force it.

i've not installed any myself, but it is my understanding that the AV
and EE fittings on the group neck are different, and the EE ones are
threaded on the inside. AV units have no gicleurs.

my recommendation would be to get a BSPP tap and thread that fitting,
or get a threaded fitting from ESI, or thread the fitting for NPT and
get an orifice from McMaster (I'd do the latter).

if you're not handy that way, drop me an email... i've got taps and
fittings.

Those gicluers look like they are for an E-61 grouphead (which is under the top
nut). I don't see how those would fit your Linea. The only option I can see
would be to drill and tap one of those compression fittings. Of course, that
only works if there is enough material to do that without weakening the fitting.
I don't know which one is the correct one, you'd need to determine that. The
good news is that those compression fittings are easy to replace should you
goof. Dan
