Easing Protractor

Easing Protractor: The body and arm are made from 1/4-inch plywood.

To mark the top cut on a volute easing, I set the protractor on the positioned handrail, then swivel the arm until the bubble reads level and tighten the set screw.

With this setting locked into place, I place the protractor against the fitting and align the lower blade with the bottom cut on the easing. I then mark the upper cut where the pivot arm touches the easing.
