Doing a fine looking job on that chimney, and giving a good answer to a question I had myself, regarding the copper tube. Great job, can't wait to hear it run Mad Jack |

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 :doh::-- Soldered one of the brass bars to the dome :lol: :D 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 Stew |

Stew, that is really the first part of your boiler! As I mentioned in the elbow engine post, I got to meet Stew on Thurs and he showed me this engine running too - sounds very powerful with a great exhaust beat. Sure it will be an excellent steamer. Nick |

Thanks Nick it was nice meeting up with you and chewing the fat. Now you come to mention it yes that is the first bit of the boiler never thought of it that way, I've just got to get the rest of it done now, I,m thinking of starting another topic just for the boiler build. Cheers Stew |
