Propertional Dividers

#1

You can measure life models more accurately with a pair of proportional dividers.

Hold the tool at arm’s length and use the large arms to take an optical measurement.

The small arms will produce short measurements in direct proportion to the large measurements. You can transfer those small measurements to your paper.

By sliding the fulcrum, you can adjust the reduction ratio to better suit the scale of your drawing.

And there’s always the good ol’ “holding out your thumb and pencil.” :smiley:

Thanks, and no thanks, this will scratch my $1000 monitor :wink:

I’d hate to imagine the damage you’d cause with Sargent’s lead-weighted plumb line.
