caption_attribution_description: English: The Stuart No10 steam engine (made from a set of castingsa nd fixings) is a classic first project for many model engineers.
context_page_description: Stuart Turner Ltd is a British engineering company, based in Henley-on-Thames, Oxfordshire, England, founded by engineer Sidney Marmaduke Stuart Turner in 1906.
context_section_description: No.1
  The original vertical single-cylinder steam engine, bore 2 inches, stroke 2 inches, standing 13 inches high. With single sided support casting and slipper guide, this form of engine is designed to run predominantly in one direction. Still available.
  No.2
  A short stroke high-speed version of the No 1 single–cylinder steam engine withdrawn in the 1920s.
  No.3
  A compound twin–cylinder vertical engine, bores 1.25 inches and 2.25 inches, stroke 1.5 inches. Also available as non-compound. This has single-sided support casting and slipper guide as common in marine engines
  No.4
  A vertical single-cylinder steam engine, bore 1.5 inches, stroke 1.5 inches, standing 10 inches high. With A-frame castings and trunk guide.
  No.5
  With a 2-inch bore and 2-inch stroke, a heavy 7-inch flywheel, it stands 14.5 inches tall, which is higher than the number 1. engine. It also runs at a higher speed and produces more power than the number 1 engine.
  No.5A (Cygnet)
  A vertical single-cylinder steam engine popular for steam boats, bore 2.25 inches, stroke 2 inches, standing 15 inches high. With A-frame castings and trunk guide.
  Swan
  A vertical twin-cylinder steam engine comprising two 5A engines on a common baseplate, popular for steam launches, bore 2.25 inches, stroke 2 inches, standing 15 inches high.
  No.6A
  A 4 HP compound twin-cylinder vertical engine, bores 2.25 inches and 4 inches, stroke 3 inches, standing 20 inches high. A favourite for larger steam launches.
  No.7A
  A vertical single-cylinder steam engine, bore 1 inch, stroke 1 inch, standing 7.5 inches high. With A-frame castings and trunk guide.
  No.8
  A horizontal single-cylinder steam engine, bore 1 inch, stroke 1 inch, 8.5 inches long, with slipper type crosshead guide, so designed for single direction of rotation. This engine is listed in the 1960s with a trunk type bored crosshead guide.
  No.9
  A larger horizontal single-cylinder steam engine, bore 1.5 inches, stroke 1.5 inches, 11 inches long, with a slipper crosshead guide, so designed for single direction of rotation.
  10V
  A small, vertical, single-cylinder steam engine, bore 0.75 inches, stroke 0.75 inches, standing 6.5 inches high. The earliest versions of this engine had a single-sided support casting and slipper guide like the No.1, however this was changed to an A-frame casting and trunk guide allowing equal crosshead support when running in either direction (also easier to make on a lathe).
  10H
  A small, horizontal, single-cylinder steam engine, bore 0.75 inches, stroke 0.75 inches, length 6.5 inches. This has a trunk guide so the crosshead is equally supported for either direction of rotation.
  D10
  A small twin-cylinder vertical steam engine (based on 10V), bore 0.75 inches, stroke 0.75 inches, standing 6.5 inches high.
  Score
  A small twin-cylinder horizontal engine, a double 10H, bore 0.75 inches, stroke 0.75 inches, length 6.5 inches.
  S50
  A small horizontal single-cylinder steam engine, bore 0.625 inches, stroke 1.25 inches, length 8.5 inches.
  Beam
  Central column style beam engine with Watt's parallel linkage, bore 1 inch, stroke 2 inches.
  Half Beam
  Grasshopper-style beam engine. Bore 1 inch, stroke 2 inches.
  Major Beam
  A larger beam engine based on a model published in Model Engineering magazine in 1914. Bore 1.75 inches, stroke 3.75 inches, 18.25 inches high.
  Victoria
  Typical of low-pressure horizontal Victorian factory engine, 1-inch bore, 2-inch stroke, 15.5 inches long.
  Twin victoria
  Two Victoria engines driving a common flywheel.
  James Coombes
  Based on a table engine that ran at a Bristol colliery, from 1970s, 1-inch bore, 2-inch stroke, 14.5 inches high.
  Real
  Another 1970s introduction based on a colliery engine. Overhead crank engine, 1-inch bore, 2-inch stroke, 15.5 inches high
  Williamson
  A model based on an engine made by Williamson of Kendal. This model was researched and designed by Tom Walshaw (pen name Tubal Cain) in 1976. Bore 0.625 inches, stroke 1.125 inches, 11 inches tall.
  Oscillator
  Also listed as the "S.T." engine. The cylinder pivots, thereby alternately uncovering inlet and exhaust ports (see oscillating
