Conway (3.5 Gauge)

Overview
Conway is a representation of an 0-4-0 Quarry Hunslet by Martin Evans. Best described as "inspired by" rather that an accurate model, the locomotive is a good size for a 3.5" locomotive (the prototype being narrow gauge).

Prototype
Conway is broadly based upon the ubiquitous Quarry Hunslet locomotives used in the slate quarries in North Wales. However many of the dimensions are not very representative of the real locomotives, such as the cab height.

Drawing Errors
Caution is urged as these drawings show quite a number of errors. Each component should be checked against other mating components prior to machining. Some errors are listed below but this list is not complete.


 * The Valve rod guides are shown as having six mounting holes on the drawings, however the stretcher is only shown to have four holes per guide. As a result either the Rod guide or the stretcher needs to be modified to make the number of mounting holes the same.
 * The boiler is listed in the magazine article and drawing as being 14 inches long, however in a later article it is noted that this is an error and it is actually 14 1/4 inches long. This could prove to be an expensive mistake and therefore caution is advised. The correct length is believed to be 14 1/4 inches.
 * Many of the holes in the frames are believed to be in the wrong place and should be double checked before drilling.
 * The blast nozzle is wrongly marked as being 11/16. The correct total height has not been confirmed at the present time.
