Thanks Jack
Now for the inner steam dome, the regulator fit in this and sits on top of the boiler where the dry steam collects. Its fabricated from 1 1/8 dia copper tube and copper/Phos bronze:- here are the bits set up for soldering, I used the brass bar to keep the copper collar in place.

Whoops

:-- Soldered one of the brass bars to the dome


Never mind just cleaned off when I set the job up true in the lathe to clean the face that will seal on the boiler.

Last job drill 12 holes in the collar for bolting to the boiler, using the PCD feature on the DRO.

Thats it another one off the list.

Cheers
Have fun
