Photocopy scales
Posted by wychdoctor92394 on Monday, June 4, 2012 2:43 AM

The first time I ever saw it, was in an issue of FSM in the mid-to-late 80's and it was a photocopy scale, so if you had plans in 1:72 scale and you wanted them at 1/32 scale, you blew them up by 225%, but it was for multiple scales

Does anyone have a copy of that scale?

Email me at:  if you can spare a copy of it.

With all due respect, you don't need a scale. Just a calculator.

Take the main number of the scale of the plans you have. (For example, if your plans are 1/72, you could actually divide 1 by 72, but it's easier just to use 72. It won't affect the results.)

Divide by the scale of the plans you desire. (e.g., for 1/144, use 144.)

Multiply by 100 to get a whole-number percentage increase or decrease.

72/144=.5 ; .5 x 100 = 50(%)

Run your 1/72 plans at 50% and they're 1/144.

It doesn't matter which number is larger or smaller, as long as you geth them in the right order. If you've got 1/72 plans you'd like to make 1/32, 72 divided by 32 = 2.25 x 100 = 225%

It's not even math. (I hate math, like most everybody else.) It's just arithmetic.
