Wow!

Worth the work?

It looks like Art Neuvuex! :D

My French is horrid, but I look at this picture and think:

C'est ne pas un Pavoni :)

Anyone can say what they will but to me it is now proven that the Europiccola looks good even upside down!
I am glad that you went ahead and gave it a try... I was thinking about it and was just too lazy to do it. :oops:

The only issue, that I can see, with the orientation that could not be easily fixed is the elements. You would have to fill in the boiler every shot or 2 just to keep the element immersed?

What you need is an element that screws into the original full cap port...

My version of the gravity fed la pavoni was to mount an open "boiler extender" using the threads of the cap with the dipper tube removed or rotated 90 degrees. I sent an email to Barb and Doug months and months ago about the idea and how to get a threaded tank or used Pavoni boiler with connection tube. I did not know what I would have done about the pressure release valve and whether it would leak. That's where that idea ended.

Kurt,

As regards the title of this post - You have made it. It is no longer "Just an idea."

Good one and congratulations!

One problem I don't see being solved is that the water inlet is very small for a non-pressurized preinfusion.
If I find a small heating element people use in chemistry classes I'll reinstall the freak.

On that leaking:
Isn't there a cap nut that would fit the pressure valve thread?

Ive considered something like this before, but I never planned to use the pavoni boiler in any of my designs, just some generic type of kettle with a tap leading to the pavoni group mounted much lower. I dunno, seems to me that it would be easier to build a boiler than try to modify one made for a particular orientation.

To continue the cheap ass experiment, I was thinking to pick up something like these:

Dutch: Dompelaar
German: Tauchsieder

What do you people recommend? 300W - 1000W? With 300W, you could add some cheap diimer for control. Just an idea, of course. Who needs pid and god knows what's out there. Glue-on flat elements with buit-in thermostats, any good stuff I don't know about?

Francesco Ceccarelli donated some beaten up parts to make a permanent version of this. Thank you!
Except for the group piston, I have everything lined up.

Right now, I'm thinking of an elegant way to plug the holes in the top of the boiler. I mean bottom. Of course, these are not standard metric threads and the hardwares stores only want to order a big box of special nuts. I don't think so...

Any suggestions for a cheap ass leverist? Ideally, the budget is nearly 0.
