Some of you may have seen this engine and boiler combination elsewhere, if so please forgive the intrusion - I've posted it here with the intent of providing a a more complete record of Inky Engines on MEM.
This is the first steam boiler I've built, and was fitted in between builds of Elmer's Grasshopper, and the combination of Elmer's Mill and Factory Engines. It involved my getting to grips with silver soldering ... also a first. I decided to pair the boiler up with an example of Elmer's Fancy Wobbler built entirely of brass and stainless steel. The engine was built as a gift, and will soon be on its way to Florida.
The boiler is based loosely on a design by Stan Bray in his book 'Making Simple Model Steam Engines'. It is silver soldered throughout, pressure tested to 120 psi and with a relief valve set at 30 psi. Originally I intended that it would run on solid fuel tablets but it took about 60 minutes to produce steam - a 1" diameter ceramic gas burner achieved the same result in 4 minutes!
An 'interesting' first run of the engine / boiler combination is included in video:
So now its back to the Mill and Factory engine builds - both are running, but I want to change some of the fixings to studs and nuts ... will post when complete.
Kind regards
Geoff at Inky Engines
