OK… lets 2+2 = 22 and… wait… no… thats not right.
New math…well, you are probably too young for that to mean anything…
isn’t that something having to do with the way Math is being taught in schools or something?
back to railroading (and CORRECT measurements/conversions)
Yeah. It came about in the 60’s and 70’s, it sort of went away from teaching compuational skills and tried to teach more abstract concepts really early on. Of course then kids didn’t learn the computaional skills which led to the 'rithmetic part of the 3 R’s getting lots of emphasis later. Now, of couse the calculator ([soapbox] invention of the devil) has gotten us away from compuational skills to the point where we can’t even count change (or figure out where 3/4" is, to tie back in to the subject at hand).
Rant off…
… i don’t even have a ruler handy, LOL
I know where it is though… the rulers I have are the ones with the 1/32nd marks between the 0" and 1" marks, and then 1/16th thereafter.
I need to get a MRR ruler…it’d make these things a lot easier…
That’s how my measuring tape is, I think. Although the 32nds might only be for the first 1.2 inch. A scale ruler is handy, especially for building things. N scale isn’t too bad though, 40 feet is three inches, from there you can take a pretty good stab at a lot of things.
The reason I suggested using the Archetectural or drafting scale ruler is the KISS principle (Keep It Simple Stupid). You can read the scaled dimensions of the drawing directly from the ruler’s markings, no conversion formulas are needed.
1 inch equals 25.4mm! so 3/4 of an inch would be 19mm,
useful and quick way to get a grid is to insert a table in microsoft word and specify the column and row heights as 19mm or 0.75inch, then in borders and shading I set the lines to one of the grey tones and have ready made planning paper.
You beat me to the post. If college student doesn’t know how to measure 3/4" on an english scale then the grade school, middle school and high school he/she attended needs to have it’s accreditation reviewed, as well as the college. I just hope this person is not a math, engineering or architectural major.
I admit it would be difficult to measure 3/4" on a metric scale as they are different measuring systems. You would take 2.54cm x .75 = 1.91cm.
Yep. Adding metric to this situation just adds another conversion/layer of abstraction. We’ve already got a scale drawing of a scale railroad! At least multiples of 3/4 are easy to do, 1.91, not so much.
