Scale Rulers

I've seen some excellent YouTube vids where the modeller was using a Scale Ruler to accurately scratch build O Scale buildings.

When you are designing buildings and detail stuff do you bother with these?

I do when modeling HO, with 1/4" scale a regular ruler works just fine.

Scale rulers also allow you to use the HO plans in model magazines, for example, to build O scale items. Measure the length on the HO plan using the HO ruler. Then, transfer that number of actual feet and inches to your work using the O scale ruler.

Many scale rulers come with multiple scales for this purpose.

When you get used to using the scale ruler, you will find yourself thinking in terms of scale feet and inches instead of actual inches. You will be thinking, let me cut that scale 2x4 to 4'6" in length instead of to 1-1/8".

Also, if you want accurate dimensions, stay away from the downloadable versions that you print out yourself. They are OK for rough estimates, but you can't beat a good metal scale ruler with multiple scales if you intend to do any amount of model building. Smile

You can go to Staples and buy a three sided plastic ruler used for Engineering. It will have aregular scale in inches and also 1/8, 3/16. 1/4. 3/8 and 1/2" per foot graduated scales on it.It is a relatively cheap item to purchase and you will be all set.

Exactly, O is 6.35mm to the foot, learn to work in millimeters and you only need one ruler.

I found copys of all scale on the net,free down load. Just make a few copys and paste them to an old ruler or just use it to get you measurements right off the paper.

Yes, I use a steel one with all the scales on it.  The old eyeballs aren't quite reliable!

Got 3 or 4 of the steel ones in the shop just I can find at least one with some reliability when I need it the most.

 

Then again, I generally just cut long and sand everything to fit since cutting to fit seems to be getting harder and harder to do these days.....even with new lenses,

 

No, no, no....  You obviously have not been paying attention to what I'm about to tell you...
