    Thanks for the video.  It has been 25 yrs since I used a scale and this video was easy to understand.  I initially bought an engineers scale but am returning it for an Architects Scale.  The metric folks need to get over themselves. Thank You!

    mharichu, there are many scales that can be used. one must first decide which scale will fit on the paper, and will allow seeing the details. This example is using a scale of 1/4" = 1', one quarter of an inch equals one foot. After deciding on a scale, simply use that scale along the edge of the architectural scale. With a few practice projects, you'll see it not complicated.

    Allen Spence, the model (I used to build them too) is 1/24th scale. So find a scale that has a 24. The 1 along that scale represents 1', one foot, along the real car. So if you need a rollbar crossmember that's 3'- 4" on the real car, it will be to the number 3 on the 24 scale to equal the 3', then 4 slashes to equal the 4". The numbered slashes are the feet, intermediate slashes the inches.

    you should never use a pen or marker on a scale. this will stain the tool.
