How do you calculate HO scale?
How do you calculate HO scale?
HO scale is 1:87.1 ratio. If you have 36 HO scale inches, just divide it by 87.1 giving you . 4133 real inches, or just a bit bigger than 3/8″ (. 375″).
How do you convert drawings to scales?
To convert a scaled measurement up to the actual measurement, simply multiply the smaller measurement by the scale factor. For example, if the scale factor is 1:8 and the smaller length is 4, multiply 4 × 8 = 32 to convert it to the larger actual size.
How long is a foot in HO scale?
In North America, the National Model Railroad Association (NMRA) standard “S-1.2 General Standard Scales” defines HO scale as 3.5 mm (0.1378 in) representing 1 real foot (304.8 mm) – a ratio of 1:87.0857142, usually rounded to 1:87.1. The precise definition of HO scale varies slightly by country and manufacturer.
How big is an acre in HO scale?
An HO scale area would be 1/87 x 1/87, or 1/7569 of real area. Or it would take 7569 HO acres to fill one real acre.
Is HO and OO scale the same?
The difference between the two scales comes down to size. HO Scale models are built to 1:87th scale, meaning 87 packed together will in effect be the same size of the real thing. This is the correct scale for 16.5mm gauge track. OO Scale will appear slightly larger to HO Scale models and accessories.
Which is the best smoke generator for model railways?
SEUTHE – Model Railway Smoke Generators for All Scales This Nurnberg-based company is the world’s leading supplier of smoke units for model railways and have a broad range with smoke generators to suit almost every modelling application as well as a range of smoke oils
How do TRS trains make steam trains work?
Interestingly, this isn’t using conventional smoke generators such as the oil-filled Seuthe type – the TRS Trains products make steam with bottled water with the exhaust effect synchronised to the sounds of the locomotive for added realism.
Which ‘OO’ gauges can have smoke generators?
Our sample model was a Hornby Stanier ‘Princess Coronation’ 4-6-2 for ‘OO’ gauge, although TRS Trains can install these smoke generators in almost any locomotive in both ‘OO’ and ‘O’ gauge. The smallest locomotive it has tackled yet is an EFE Rail Hunslet ‘J94’ 0-6-0ST.
