Subject: convert plumbed to pour over
|
The friend that bought the Nuova Simonelli Personal on eBay has an odd
request. The machine is set up for direct plumb & drain and has a perfectly
good rotary pump & motor; so of course he wants to convert it into a pour
over. I've been looking at it for a while & tried talking him out of it;
might as well be talking to the wall. So, here goes!
Once the motor & rotary pump were pulled there's room for a good sized
permanently mounted water reservoir if I route a fill tube through the
machines guts. I'm also going to put in a sight tube since the reservoir
won't be visible externally. The reservoir itself will be fabricated at the
shop from 20 gauge S/S sheet stock & will have a pet cock for draining. Oh
yes, the machine is wired for 240v 60Hz & I'll leave it that way. I've a
couple 240v 50Hz 48w Ulka pumps in excellent condition that I pulled from
other machines. I'll use copper tube & compression fittings to feed the
beast.
Other than the fabrication of the reservoir & drip pan I don't foresee any
problems. So, what am I missing?

Usually tank fed machines have some provision for shutting off if the tank
runs dry - otherwise you can end up burning out the pump/ heating element.
Typical systems are either weight driven (mount the tank on springs with a
microswitch, when the tank lightens the contact breaks) or rely on running a
small current thru the tank - when the tank goes dry the current cannot pass
thru air. You might have to salvage the "brain box" from a pourover machine
to implement this, though the electronics are not rocket science - a low
voltage circuit and a line voltage relay in series with the main power
feed.

Robert, it is my understanding that such items as the flow reducers
(gicleurs) are designed to take into account the flow rates and pressure
curves of the particular pump type. There are some differences in, for
instance, these parts in the Unic Phoenix and Diva machines, the former
vibe pump, the latter rotary.

Because I don't know, why change the pump from rotary to vibe?

Not that much heavier.

Why not use an external tank, like a jug of bottle water, and leave the pump?
How will you provide for easy draining of the reservoir if it is going to be
moved often?

Just replacing the rotary pump & motor & associated small parts with an
oscillating pump will shave 15+ lbs. We're planning on a petcock on the
reservoir & boiler to make draining faster & easier.
This will be a replacement for the espresso machine in the neighbors RV.
Currently he has a Silvia & Mazzer Super Jolly sitting on a spring-loaded
pull-out shelf that's rated at 85 lbs. We're hoping to trim it from 97 lbs
to under 70 lbs. We're also looking at some other areas where we can trim
some weight, such as replacing the S/S & plastic panels with .020 T7075
anodized aluminum sheet stock we have just laying around in the shop.
Anyway, that's our plan as it stands now. We're sure the weight goal is
attainable & the results should justify the effort. Besides, if it was easy
would it still be fun?

That's why he got the NS Personal, he agreed it was past time to get rid of
the Silvia. Now he's got a real machine to work with. I just wish it weren't
so heavy.

Well, my La Cimbali M32 Classic will see your Spaz & raise you a Livia. Do
you only engage in pissing contests Dave? How about starting off with your
own thread about something you've learned how to do with these machines that
the rest of us can use on ours? You must have a few "tricks of the trade"
up your sleeve.

Dave, you are the Epaminondus of alt.coffee. Every time someone gives
you a compliment, you say something stupid and spoil it. <grin >
