Peter Douglass – Tips on Scaling

The following calculations are the work of Chief Eng. Ron Phillips when scaling his model of the “R.M.S. Queen Mary”,Which he wanted to build at 1/16” scale.

1. QUEEN MARY length @ 1010 feet-6 inches at 1/16 Scale.

1010.5 feet   =  63.16 inches
16

1/16”    =    1.192 Scale

1010.5
   X   12 ins/ft.   =    63.16”
192

If you know the length of the model you want to build and want to know the scale to build it to:

i.e.   1010.5 x 12   = 63.16”  i.e.  X  = 1010.5 x 12
Scale X  ?                            63.16
SCALE   =   1:192   or  1/16”

***********************************************************

2. Your BOAT/VESSEL @ 267’-0” and at   1:50 Scale

267’-0” x 12”/FT. = 64” (Model may be too long !)
50

Assuming you would rather build a smaller model, say 36 inches, and want
to know the scale.

i.e. 267’-0” x 12 = 36   X = 267’-0” x 12
Scale X ?                              36”

SCALE  = 1:89   or  9/64”
SAY………  1/8” to the Foot!
