Measuring tool

Working from any drawing might be easier with this kickstarter product.

I don’t know anything about the product or the company behind it other than what is on the Kickstarter page.

Just a (hard-learned) reminder. Supporting a Kickstarter is being a very small scale venture capitalist. You are not actually buying a product and there is a definite chance that you will never receive anything for your money. It's sometimes worth it, sometimes not.

I’m aware of the risks… they’ve done 4 other kickstarters to competition. They’re talking about shipping in June. IF I get one delivered I’ll post a review.

Although I generally like to work from a drawing that I’ve adjusted up or down to the scale I’m working with on a copy machine, I picked this up from Micromark last year. As well as converting a drawing’s
 dimensions to a different scale, I’ve found it works well to verify if the dimensions on an existing model match a scale drawing. |

Never used them while in the AF, but great for modelling, and they look and work as good a new 40 years later. -- Bill Parks Cumming, GA Modelling the Seaboard Airline in Central Florida |

I do it a different way. I drew an HO scale in a drawing program and then print it larger or smaller, depending.
The attachments show an example. I needed a scale measurement that was coming from a plan printed in a book. There was no scale listed, but there were a few measurements on the drawing that I could use. By using a caliper to measure the distance on the drawing and a little math, I found out that a 1.5x enlargement of my scale would get me close. Using that scale, I refined it to a 1/83 X 1.5. That got me extremely close.
One warning if you try this: The scale of a drawing in a book may not be scaled the same horizontally as it is vertically. Check to be sure!

This is very common in printed plans from books and magazines, so common as to be expected. It has to do with the paper stretching as it is fed off of giant rolls into the printing press, then shrinking after it's printed. When I am forced to scale (measure directly from) a printed drawing, I often establish seperate scale factors for the vertical and horizontal measurements. Dennis Storzek |

I do most of my work in actual inches. Back when I was involved with making scale drawings from pictures to make freight car patterns, I needed to make scale conversion ratios. Since most pictures are not directly broadside, and if they were keystoneing becomes a problem if the lenses used were not long, so I would select a vertical line at one point on the photo and with help from equipment registers I selected a distance which I could get a true real height. The known real height ratioed with the pictures measured height was my ratio useful only in that one vertical area. Count 10 boards up on a single sheathed car and divide by 10 and multiply with the conversion ratio and you have board width. With both a dial caliper and a calculator at the ready a divider was unnecessary. -Andy Carlson Ojai CA |

I’ve had one for 40 years and use it frequently. It is also great for finding the center or thirds on surfaces, etc.

Has a retired Draftsman. Started on the board ended on the keyboard.
One lesson I learned early on. Don't measure off a drawing. Parts of the drawings, sections, details, plans and elevations drawings may not be correct using the scale. Especially in the board era, was common for a last minute change. Not enough time to re-draw to beat the deadline. Erase the dimension callout and pop in a new number. DONE. Rare to good back and rework the drawing(s). CAD, not has bad, but still occurred. Has previous post. Enlarge and reduction can really mess a drawing up. If it isn't dimensioned, DON'T ASSUME. Numerous times seen when adding dimensions, didn't added up to the overall dimension. Unfortunately for us. Not having the real item or drawings. Well, just double check. Fortunately we're doing models and not a prototype bridge. Reuben @ Poplarville, Ms |
