size of scale railings

[eckloss]

How high should a ships railing be if done in 1:150 scale? for some reason I'm having a brain fart. guess I'm getting old.

If you have Excel here is a spread sheet you can modify to get the scales you want.

If you do not have Excel you can down load the FREE WPS Office which has a full spread sheet that reads Excel with only a few odd things.

Erich,

No need for a spreadsheet. This is just simple math. If you know the height of the 1:1 scale railings, then (in your case) simply divide that number by 150.

Jeff,
That's the easy way.
But it is also true if you convert all full size numbers to inches before dividing by 150.

I built the spread sheet to make the math take care of itself.
It makes it easier to keep track to build boats from scratch.
I could measure a drawing and enter all the numbers I could lift and then refer to it as needed.

To get scale size in inches, the original full size measurement must be in inches before dividing by the scale.

Example of 5 foot item to 1/150 scale. . .
5 feet times 12 inches = 60 inches
60 inches divided by 150 = .40 inches
-
If the 5 foot item is not converted to inches and divided by 150, the answer would be .0333" and incorrect.

To get original real feet directly to scale inches...divided by 12.5.
5 feet divided by 12.5 = .40 inches.

In my haste, I may have made a mistake in the process.
If so, please point it out and so I can correct it on my end.
Ralph

I have used spread sheets since they became available. (Profile Plus to Lotus 123 to Excel)
Haven't used a calculator much since.

If the 5 foot item is not converted to inches and divided by 150, the answer would be .0333" and incorrect.

Actually, that result is correct. It's 0.0333 feet. You cannot divide a dimensioned number (i.e. 5 feet) by a dimensionless number (i.e. the 150) and have a result that is a different dimension.

If that result of 0.0333 feet is too small to work with then convert to inches by simply multiplying by 12.

I have nothing against using spreadsheets to aid in various tasks, I use them myself, but for a staright-forward question like Erich asked it's simply easier to do the math.

Jeff, thank you for pointing the error of my not keeping feet to feet.
I labels the answer as inches when it should have been feet.
I completely failed in continuing on to converting to inches.

I am usually using photos and poor line drawing when scaling parts to numbers.
And you are correct in that Erick asked a question that should have been given a simple answer.
All I did was complicate the issue.
Sorry, Erick.
And again, thanks, Jeff.
