I have decided to make a Hobbies Arrow for my Granddads Christmas present this year!
I decided, that I would rather make the engine and boiler for it than buy one ready made! The engine is built to the design of Stan Brays 'Slim Sam' in his book 'Building Simple Model Steam Engines' and I am basing the boiler upon that of a Bowman M135 - I shall probably use copper as opposed to brass however...unless anyone has some 1 1/2" brass tube?
Had a few hours spare in the workshop today, so I decided to make a start on the engine...
Firstly, a flywheel, this still needs the fixing screw hole drilled and tapped inside it.
The Crank...
Start of the cylinder...
Cylinder End Cap...
...shall probably remake this to my own dimensions to fit fit the cylinder better. I made the end cap first and didn't think of checking...
Piston...
As it's going to be based on a Bowman, I needed one of these...
...so...
...still needs the hole drilled in for the little brass lever on the side and I need some 1/8" stainless steel rod for the middle...
...not exactly a rival to MF Steams replicas, but not bad. Shown with boiler bush.
Shall hopefully get a bit more done this week, plan to make the lubricator, filler plug and other boiler bushings next!
