Thx. They are all machined, but I still have to take the chrome off the rest of the batch. It would just be simpler to have the part remade from scratch, but they are not inexpensive and I don't like to waste all the material/energy/work that went into making them.

Awesome build, Looking forward to the result !

Cheers,

Hi Fred - thank you. The prototype should be finished pretty soon.

The brugnettis are great machines if ever you get another opportunity - Dr. Pootoogoo and I have started a collection of them here.

A man after my own heart! A coffee craver with A+ machining skills and the drive to do a great project. And...the wherewithal to get it done!
Well done and keep the information coming!
Thank you!

Thank you for the kind words and the encouragement!

Two things to write about today.
Number one: I gotta package in the mail! I love getting packages and this one is particularly satisfying.

The customs label said "Dslr camera cnc components from professional factory". Inside is one bag of some individually-wrapped-in-a-twist-of-white-paper things.



Candies?



Oh yeah. The real deal: 7x32mm stainless knurled dowel pins custom made to my specification.



There just wasn't another choice here so now I'm the proud owner of what might quite possibly be the only new stock of this theoretically standard part in the world.

The second thing.

Last time I was fortunate enough to be in Rome, I came across the Shakerato, which, ten commandments notwithstanding, I covet. So of course, I decided I had to make one! Sort of.

Starting with a hockey-puck-sized piece of Acetal, I cut out an internal bore to fit a bearing.



(Of course, said bearing is a surplus part from a grinder restoration).



Cue appropriately themed music:
The rest of the first part of the build is here.

incredible multi skills, precision work; nice job!

Thanks for sharing.

Thank you Danny!

I'm still wading my way through tests and test results but I have finally managed to get the designs for the controller PCBs finished and sent out for fabrication.

Feature set:

1.3" oled screen with 5 button keypad
2 x A2D PT100 thermocouple sensor inputs
2 x A2D K-type thermocouple sensor inputs
auto-fill sensor
auto-fill solenoid driver (120/240V AC)
SSR driver (5V DC)
real time clock with battery backup





I should have the bare boards in a couple of weeks.

And the next part of the Shakerato II build is up here.

I see no processor, what will power it?

Indeed - there is no processor on either of these pcbs. The first board is a shield for an arduino mega and the second is a daughter board for the shield. It isn't worth the work to design and (especially) fabricate a whole board around a processor at this scale of production. To put it into perspective, 10 mega boards cost about $10/unit. I would cost me much more in time just to write the bill of materials, before even beginning to factor in development and fabrication. A few iterations down the road and I may consider designing a single pcb from scratch, but even these boards, that are essentially just breakout, were a fair amount of work.
