Model Railroading > Reducing 1/4" scale drawings to HO scaleDate: 11/19/20 12:21 Reducing 1/4" scale drawings to HO scale Author: boejoe I'm sure it's been addressed here in the past. HO is 3.5mm to 1 ft and generally O scale is 1/4" to the foot (17/64" to the purists) I want to reduce an O scale drawing to HO scale and ask what copier reduction setting I use to achieve the correct result. TIA for your assistance.

TIA for your assistance. 1/4 inch = 6.35 mm 6.35 / 3.5 = 55.12% TAW Date: 11/19/20 13:12 Re: Reducing 1/4" scale drawings to HO scale Author: boejoe Thanks Tom.
Date: 11/19/20 13:27 Re: Reducing 1/4" scale drawings to HO scale Author: randgust Another way to do this - if you don't have a copier with that level of sophistication but do have a scanner/printer:
Scan the drawing in as a .JPG, making sure it has a printed dimension somewhere on it. Insert the JPG as a photo into a Word document Resize and print the image back out, adjusting it for size until the printed dimension matches a scale ruler laid on top of it. You can keep printing and checking until you get it right, no harm, no foul. |
