2x3 tubing size

[flatheadgary]

i am in the process of building a frame of my 1-1 car and it is made of 2x3 tubing. doing the math seems the size is .080x.120. is this correct? my math is not all that good anymore since i retired. i believe you divide the 2x3 by 25. any help would be appreciated. thanks in advance.

Yes, it's that simple: Just divide the 1:1 dimension by 25, and you'll have your 1:25 scale dimension. One inch equals one millimeter in 1:25 (or close enough anyway) so the quick and dirty way is to use standard dimensions when measuring the 1:1 car, and use metric dimensions when you build the model. Most Evergreen material I have seen will have standard and metric dimensions printed on the bag, so what you need to look for is a 2x3 mm rod.

Edit: I just looked at Evergreens web site ( http://www.evergreenscalemodels.com ) and they have a .080 x .125 (2,0x3,2mm)

rod that should be close to what you need. There's also a neat scale conversion chart for other dimensions ( http://www.evergreenscalemodels.com/conver...ersion%20Charts ).

thank you olle f. that is exactly what i needed.

You're welcome! I forgot to add that I have a metric steel ruler and digital calipers that can be switched between standard and metric. These are very useful tools when you scratch build things in 1:25 scale as you don't have convert any dimensions, you just use inches and millimeters one-for-one. For example: If you're measuring something that's 6" on your 1:1 car, you make it 6 mm on your 1:25 model. Simple as that.

I keep it absurdly simple. For 1/25 or 1/24 (close enough for me) .040 on a model car = 1 inch on a real car. I also use the metric system, 1 mm is .03937 which is close to .040 as you can get.
