HO to O scale conversion question

[Anonymous]

 

Hi all:

In the latest issue of "The Warbonnet" there is an article on how to build a model of a Santa Fe stockyard, however, it is in "HO" scale. The article includes architectual plans with dimensions.

How do I convert to "O" scale?

Thanks!

Reproduce the drawings on a copier at 200%. All measurements will also have to be increased by 200%. So a building 4 inches long in HO will be 8 inches long in O.

I should have been more clear. The architectural plans are in feet and inches.

How do I convert this to "0" scale?

Example: The stockyard fence post are 6 feet apart, what would this be in "0" scale?

Thanks!

Ohhhhhhhhhhhhhh! Well why didn't you say so?

1/4 inch = 1 foot in O scale. So 6 feet would be 1 1/2 inches.

If it lists 1:1 dimensions, try a scale calculator:

Divide all measurements by 48.

HO is not half of American 1/48 O.  It is 1/87 or 3.5 millimeters per foot, half of 1/43.5 British O, which was conceived in the quaint units of 7 millimeters per foot.  Ironically, the British do not much use HO, but rather their version of OO, at 1/76 or 4 millimeters to the foot, except that they run it on 16.5 millimeter HO track instead of the correct 19 millimeter or 3/4 inch track used by Lionel for American OO.

my understanding is that from HO to O you would need to set your copier percentage at 181.4 according to MR magazine, Jan 06, page 70, if you have that issue

Another way is to use a scale ruler with HO and O scales.  Measure the HO drawing with the HO scale, for example, 5'6".  Then with the O scale ruler transfer that dimension to the material to be cut.
