That is a ludicrous amount of brass!

When I first saw the picture of all the different adapters and tees it seemed like overkill, but once you started to populate the boiler and the frame... that's about right. There's a lot of engineering and design that I was taking for granted in a modern lever machine.

Yup, lots and and lots of brass. There are a couple of assemblies that could be simplified with a custom part; but those are expensive. The input manifold especially is messy and unhelpful.
However, there isn't a lot of fat to be trimmed here if it all stays "off the shelf".

Round four - ding, ding - maybe this time?



...and some plumbing runs.

We're getting all hydraulic and electric!

All plumbing runs installed and tightened. Some re-tightened, gently sworn at, re-re-tightened, certain among which were loudly sworn at, replaced, tightened and re-tightened. Its a love hate thing.



I'm happier with the layout (hmm, drawing things in CAD first is actually helpful): the diagonal HX and smaller diameter tubing allow for a slightly simpler design and the virtual draft in the computer helped to eliminate a bunch of can't-install-this-because-that-is-now-in-the-way problems. The drain valve is now easily accessible right under the drip tray. I only put the steam tap on to, well, let off steam when I want to cool down the boiler quickly to continue working.

The new location and flange for AC distribution is far better than the previous version (i.e. there is one). I decided to switch to a terminal block rather than trying to accomplish everything inside the controller box. You can also see the T fitting that brings cold water to the HX and runs on to the expansion valve that at the sump.



Just below the T fitting is a bolt-on flange (made from a defunct IBM monitor stand) that supports the solenoid. No more free-hanging valves makes Sally the Solenoid happy:



All electrics and signal cables done. No checking for leaks - I just close my eyes when I turn it on.



Now its time to:

OH COME ON!!!!!......

You can't just leave us hanging here.......

Ok.

Yes....and?

... and look at the time on the controller. I went home after that and haven't been back since.
Maybe it worked. Maybe I don't have a studio anymore.



Porridge will be shared tomorrow.

Looking good and I'm confident the studio will still exist when you show up. Hopefully, the new group will be ready to install soon.
