“Once you have become versed in the techniques and methods described here, your abilities will have improved manyfold.”

That’s author Richard Marmo in Understanding Model Math & Scale Jumping, Version 2.0 – third in his “Marmo Method Modelbuilding Guides”.

After introductory comments, his handy handbook on practical mathematics for hobbyists covers the subject in seven easy-to-follow chapters:

The Basics
Tools
Number Crunching
Key To Model Math
Scale Jumping
Solutions To Other Problems Other Possibilities
Final Thoughts

The tips and techniques are clear – even to math-challenged guys like me. “Marmo’s Four Laws” show how to achieve the results he describes. And appendices with three handy tables help spare some common calculations:

inch/foot and ratio/proportion dimensions for a range of scales
decimal equivalents to three places for common fractions below one inch
multiplication factors for frequently used scales

But the possessive of “it” is “its” – not “it’s”. And I haven’t encountered the expression “make no never mind” since watching “George of the Jungle” as a kid!

“No longer will you be locked in to a limited number of scales”, Marmo concludes. “Aircraft, armor, ships, science-fiction, even larger than life insects or twelve foot diameter Tarantulas … anything you care to name or imagine can be created using the model math and scale jumping techniques I've described.”

And that’s well worth Marmo’s modest $2.99 price of admission.
