First was a trip to the boiler inspector, to inspect the first silver braze on the 6″ vertical boiler. Passed! And quite complimentary about the quality of the build so far.
And…. he has OK’d my plans for the Trevithick Dredger engine boiler. Which is nice because I have already started it, and was going to build it in any case. Only requirement is that I have to add a pressure gauge. As far as I know, none of Trevithick’s engines used pressure gauges, just weight based safety valves. So a pressure gauge will not exactly be in keeping with the historicity of the model, but it seems a small price to pay to get the boiler certified. Now I am trying to work out where to place the pressure gauge so the operator can see it, but not the viewing public.
Then a late entrance to our GSMEE day meeting. (Geelong Society of Model and Experimental Engineers). I showed my progress on the 6″ vertical boiler. And took some pics of some of the other items brought in by members.
and that firebox door is titanium! And check out the screws in the base…. no-one is going to be able to unscrew this model!
