Oh how the memory fades with this getting old stuff. Been into it since 1200 baud modems (got involved just after their release) but dang forgot!

Beautiful powder coating. I've seen more and more powder coated drain tray and cup rack, wonder how they will hold up in commercial setting.

Oh we all get there. I didn't even know that emoticon existed until the wife used it. She's much more savy with those things than I am.

The drip tray being powder coated is not something I would recommend. The old powder coat was actually stripped off right where the hot water from the groupheads land. I decided to just go ahead and powder coat them again since I can always strip it down the road if needed.

Finally fitted most of the pieces back together. That was a bit aggravating. Some panels were so closely fitted to the frame that some light sanding needed to be done along the edges to have it fit again. Aside from that, I am quite pleased at how it's turning out. A few more details to go and I will finally have my kitchen back!



Specht Design just got named as the exclusive detailer and custom options designer for La Marzocco Australia. He is going to be quite busy for the foreseeable future. I may have a significant wait for my group caps. However, I do have a backup option.

Wow, wow, wow, Wow, WOW. Very well done. The wood choice really made the machine.

Ha! Not too hard to do since most places that are in possession of a Mistral haven't publicized it as much as I have. I'm sure there's a crazy one out there. Maybe a full on two group Speedster aesthetic mod?! Oh heart, be still...

I'm glad I didn't opt for some crazy wood like Ironwood burl. Sourcing pieces would have been a nightmare and costly. Moreso than Zebra wood.

That's really stunning. I'd personally look into how to incorporate glass into it, maybe the cup rail like some of the more recent Kees design?
Its just there is something about metal wood and glass and you have the perfect canvas IMHO.

Ha! The cup rail was originally plexiglass. I left it on just to see the difference. I honestly think the wood evens things out a bit.

I'm still not sure what to do about the giant fluorescent light bulb on the rear of the machine.

Yesterday, I decided to do rebuild the other paddle group on my machine. The process went by much quicker than my first time. The part that actually took the longest was adjusting the paddle movement to be just right. It felt like trial and error the whole time. Anyways, everything was fine up until I turned the line pressure back on. Water. Everywhere.

I turned the line pressure back off and inspected where the leak came from. After determining what parts of the group were wet and what was dry, I realized the leak originated from the Paddle Body Valve (part B.2.012).



Of course it had to be pne of the deepest parts. After taking the paddle group apart again, I found this.



Thinking back, I realized that while tightening down part A.1.015, it was a little tight at first then I felt a sudden loosening before it locked into place. Doh! That must have been the o-ring not seated correctly and me shearing it when I forced the parts together. Lesson learned.
