Sorry it has been so long since an update but these have been some busy few months.

I've gotten two quotes for $190 and $290 for 13 round holes and 4 square cutouts for PIDS in the Boston area. Good luck with your continued build.
The local company for waterjetting fell through so I started looking online. Found Big Blue Saw
out of Atlanta that has been responsive and the prices were very reasonable (~$80 for the cutouts). As a bonus they also cut/laser engrave acrylic sheets to be used as labels or indicators (~$35). I reworked the my panel cut outs a bit for better tolerances and then created an overlay for the acrylic labels, it will be brushed stainless in look with black inlays:
I hope to ship the door to them early next week to be cut.
The circuit board design for the other components in the brewery has consumed much of the last two months of spare time. I sent all of the PCB designs off to be printed, should get them back in 2-4 weeks (BatchPCB).
First is the brewery controller:
Provides me all of the connectors and accessories needed from the microcontroller powering the sensors, valves, and elements.
Next is the breakout board for the LCD switches I mentioned earlier:
This provides a programmable LCD key for each tank and pump as well as connection points for the other front panel switches and indicators.
Finally, while I was creating the circuits I finished the controller board for my motorized ball valves:
With this valve controller I should be able to command and detect any position from 0-100% as well as detect manual position overrides.
There haven't been many updates to the brewing room itself yet as much of my manual labor time has been devoted to the yard. After these circuit boards and front panel are done the last major component for me to finish is the heat exchanger coil.
