Awe, c'mon. Not THAT bad an idea! I can see some pressure profiling opportunities in it like no other. It would actually be simpler than you may think to setup. I could go anywhere from real simple on the controls and dial in the dose and grind to a good shot at a consistent 25 sec. pull- to having complete computerized control over the pressure on the fly. I may just have to keep my eyes out for a lever that would support the motor assy.

Sorry to be so OT but this really has me thinking! Anyways got an offer in on a house and trying to keep my mind off of it ;>)

EDIT: there already patents on this!
http://www.google.com/patents/US5255594

and others!



It should be worm driven gears piston.

Ill put up my old pavoni and $2000 into the project development.
I know a guy with a machine shop that works for Philips making one off prototypes for Chinese manufacturing.

He is in the USA>

Could this thing make us rich?
Lets share within this thread ahaha.

Ok iv had a few drinks of beer by now.
But ill put up the startup and hire the machine shop who does very fine work.

moved grinder to 0 and its all the way at 0.
did an A+++ perfect pull today, all 4 perfect.

Piston on Pavoni was serviced last year.
Pulled fine.

But I still have carpel tunnel syndrome that on the puller arm.

Ordered burrs.

Posted June 1, 2014 link

Well, I have a rotator cuff issue with my right arm, and if it aches too much, I just pull with mostly my left, or do a 2 hand pull. However, my Strega weighs tons more than your La Pavoni. You have a fine lever there, and +1 for getting the new burrset for your grinder.
However, if you're having pain, I'd look for a nice pre-owned HX machine, like a Quick Mill Anita, etc. Machines like that can be had for less than 1 k, in very good condition.

Check out CG's BST (Buy Sell Trade) forum.

I guess it's not an entirely unique idea then, what I'm picturing in my head is a much simpler design though. I was thinking of something mounted on a larger machine- but now that you mention it there may be a way to mount something with the grouphead mounts on a La Pavoni. I've got one I've been meaning to finish assembling, I think I need to ponder on this for awhile. I think I'll keep a lookout for LP's sold for parts though, I may want to chop up a couple of group heads experimenting.

Not trying to cut you out of the loop...LOL, just that tinkering time on my part would be the real first step. If I come up with anything worthwhile I'll let you know, I really do think there could be something to this!

So my thinking so far and a bit of chatting with co-workers has got me contemplating that a pressure thermistor on the piston and a current monitor/regulator on the motor would be pretty easy to setup. I'm going to do some poking around this weekend (Mcmaster-Carr and such) and see what I might come up with for a motor/gearbox that would fit the bill.

hey Jay - since we're using the same exact grinder/espresso machine, can I ask you a quick question?

when your grinder reads "0" on the dial is there any noise from the burrs making contact?

The numbers do NOT correspond from machine to machine -- they only indicate relative grind size (i.e.: "0" is finer than "1," which is finer than "2" . . . on your machine; but a "1" on your machine will not be the same as a "1" on someone else's).

its not bottoming out, it is on the finest it can get,  I never got new burrs.
I just cleaned up the grinder, actually did not do much but look in and spin it with a knife and put back to gather and it suddenly works now and the machine pulls perfect!

So, in reference to your first post, you have had the GRINDER 30 years and never changed the burrs?
It is due and perhaps a little overdue for burrs, hey just an opinion here :P
NS makes a good grinder but even their grinders need to be cleaned, often. The oils tend to gum up things and then go rancid affecting the flavor of the drink.
I had an MDX for a while, good grinder and I like the adjustment system more than Mazzer SJ (I have had several)  but in the cup, they were about the same.

 
In real life, my name is
Wayne P.
Anything I post is personal opinion and is only worth as much as anyone else's personal opinion. YMMV!

Feed the newbs, starve the trolls and above all enjoy what you drink!
