Understanding Model Math and Scale Jumping

Understanding Model Math and Scale Jumping Book Review

By David L. Veres

Date of Review September 2019 Title Understanding Model Math and Scale Jumping
Author Richard Marmo Publisher Scale Publications
Published 2019 ISBN n/a
Format 15 pages, PDF MSRP (USD) $2.99


“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.

My sincere thanks to Scale Publications for this review sample!
