Examples of 'Working' Walschaerts, Stephenson, and Joy Valve Gear |
Here are three video clips that illustrate 'working' Walschaerts, Stephenson and Joy valve gear in 7mm scale (O gauge) models.
Walschaerts Valve Gear |
|
The Walschaerts valve gear is from a Great Western Castle (No. 4081 Warwick Castle) that I built from a Malcolm Mitchell kit but the internal parts of the valve gear, the con-rods and the cranked axle, etc., I made up from scratch. |
|
Stephenson Valve Gear |
|
The Stephenson valve gear is from a Great Western Saint (No. 2090 Saint David) that I built from a Slater's kit with many additions, including the internal parts of the valve gear. |
|
Joy Valve Gear |
|
The Joy valve gear is from a London North Western 0-6-0 18" Express Goods (commonly called a 'Cauliflower') that I built from a kit, formerly marketed by Modellers World, and with excellent castings for the valve gear supplied by Laurie Griffin and wheels by Alan Harris (AJH). |
