scale wheelbase

[foosh]

Tech help needed. I'm working on two AMT Westernstar's and have extended the frames 1 and 3/4 inches making the wheelbase 9 and 3/8 inches. What does that equal in 1:1 ?

[Jim B]

9-3/8" on the model is 234-3/8" on the 1:1.

Thanks Jim.

Just FYI...The AMT kits are 1/25 (1:25) scale, right? Measure ANYTHING on your model and multiply it by 25 and you get the real size. If you have the real dimension, divide it by 25 and you have the correct 1/25 scale size. Works the same for any scale.

A quirk of modelling in 1:25 scale also means that whatever you measure on the model in millimeters equates to inches on the real item. As an engineer, the mixing of measuring systems irks me to no end but this is too convenient to ignore.

That's a good point, is self-evident to a lot of us, but might need a little clarification for a new modeler. What he means is that if you measure something in full scale (1:1) to be 36" (36 inches) in 1/25 (1:25) scale it will be 36mm. It just happened to work out that way and it IS pretty convenient.

on a tandem truck the wheelbase is measured from the center of the front axle o the center of the tandem suspention.A single axle is from center line to center line

[Q tip]

1 inch=2'1"@1/25 scale

Assuming the model is accurate.

Thanks Harry... Now I need to start all over again... 1+1=2, 2+2=4, 4+4=8...
