Boiler hydraulic test 4 hours

Looks like a lovely little unit and should make the basis for a nice steam plant.

It is what, in industry, would be called an underfired single-pass firetube boiler. Quite a popular design in the mid 20th century. I’m old enough that I worked on several full sized versions over the years.

Yes, it’s an interesting design, nice to know someone who actually worked on them! The more I uncover, the more questions I have! It will be nice to get it steaming one day, still a fair amount of work to do, new fittings ect, and still wondering about insulation and firebox lining material which extends to boiler sides, easier to see once covers removed

One side removed revealing firebox

<p style=”text-align: center;”>Just noticed the water level take off from boiler, that doesn’t looked-bushed but silver soldered directly, maybe it’s stepped down and soldered? Is it worth drilling out and bushing?</p>

Probably more trouble than it is worth. There is a risk of melting other joints as you try and solder in a new bush which may then be hard to rectify.
