Since the last update<\/a>, I have had the boiler tested by the helpful people in my local model engineering society<\/a>. They also had a look at the gas tank. <\/p>\n\n\n\n

Garden-gauge steam locomotives, particularly those with commercially-made boilers, don\u2019t normally need annual boiler testing. However, this kit languished in a cupboard for 20 years, and there was no certification paperwork with it. So I felt it would be a good precaution to get it formally pressure-tested before I try to run it. <\/p>\n\n\n\n

The boiler is sound, which is a relief. <\/p>\n\n\n\n

The gentlemen who did the boiler testing also inspected the gas tank. Although they aren’t able to pressure-test it (being a gas tank, it is tested in a different way to testing a boiler), they were of the opinion that the gas tank was professionally made. The tank itself seems sound, but there was a leak coming from the valve. There is a slot on top of the valve by which it can be tightened, but this needs a special screwdriver (see picture). In the picture you can also see the screwdriver bit which I modified (with a hacksaw). With some gas in the tank, I immersed it in luke-warm water, and confirmed that there aren’t any bubbles. <\/p>\n\n\n\n

The next step is to put everything back together again, complete the assembly, and put some fire inside it.<\/p>\n\n\n\n
