larry ray Posted December 8, 2019 Share Posted December 8, 2019 How do you figure scale I would like to know how much is 8 inches 1:1 in 1.25 scale. Thanks Quote Link to comment Share on other sites More sharing options...

Thanks You mean 1/25 scale. 1/25 of 8" is .32". Just punch 1/25 of any number of inches into Google and get an instant answer. 1/25 of 12" is .48" or a tad shy of 1/2".

DPNM Posted December 8, 2019 Share Posted December 8, 2019 8 (your measurement) divided by 25 (your scale) = 0.32 inch. The exact fraction is 8/25 To get a close and understandable from a ruler viewpoint fraction 0.32 is a bit less than a third of an inch. My thought is 5/16 should be close.

CabDriver Posted December 8, 2019 Share Posted December 8, 2019 If you can get used to using metric too, it’s super easy - 1 inch in scale is (give or take) 1mm. Quote Link to comment Share on other sites More sharing options...
peteski Posted December 9, 2019 Share Posted December 9, 2019 Why go to Google when you can do this using any basic 4-function calculator? Or just do it longhand (of you still remember how). This is 1st grade math. Just take the 1:1 dimension (in inches), divide it by 25 (or whatever scale you need to use), and you get the scale dimension (still in 1:1 inches, which you do need to fabricate the part). I have couple of those tiny cheap calculators (keychains) from Staples (or Dollar Store) hanging around my workbench, just for this purpose. 8" / 25 = 0.32" I also own a $20 digital calipers from Harbor Freight, so I can dial 0.320" directly on the calipers to measure out the part I'm making. Those are couple of (very inexpensive) tools I find indispensable in this hobby. Quote Link to comment Share on other sites More sharing options...

It is most assuredly a must have tool for ANY fabricator/mechanic etc... Quote Link to comment Share on other sites More sharing options...
Tom Geiger Posted December 13, 2019 Share Posted December 13, 2019 (edited) Why do any math? Here's a couple 1/25 scale rulers. Put it up against your model and measure it off accurately in scale!

Flat32 Posted December 13, 2019 Share Posted December 13, 2019 If I were to try scratch building the scale I'd choose would be 25.4:1 or a simple 1mm=1". That way a digital caliper in mm mode would simply be read as 1:1 scale inches. A metric dial caliper would be the same only lacking the ability to switch the measurement to actual inches. Using 25.4 as a scale might allow the scratch built model to "fit" reasonably well alongside either 1:25 or 1:24 kit models. Quote Link to comment Share on other sites More sharing options...
