Bolton 9 Triple Expansion Steam Engine
My next steam engine project will be to make from iron and gunmetal castings and bar stock, a steam engine which will have similarities to the engines of the Titanic. It will have 3 cylinders, increasing in size, so that steam passes from the smallest to the intermediate to the biggest, thus being used 3 times before being exhausted. It will be much more complex than the other engines pictured to date on the blog. My other engines have taken about a year each to build, so I predict that this one will take a similar time. We will see. There will be no rush. My aim is to enjoy the build and end up with a working engine. It might even end up in a boat.
I have the plans, and the castings are on order. The supplier (Kelly Mayberry at E&J Winter, Sydney) had to order new castings, so they are currently being cast and collected. My next post will be when the castings arrive. If you are interested, go to the E&J Winter web site and browse the catalogue. I am not exactly sure about the final cost of the castings but it will be approx $A1500. Not cheap, but SWMBO says that it keeps me off the streets, and is probably less than belonging to a golf club.
