What are Trammels used for?

A trammel is usually used when you have to draw a big circle or arc that cannot be handled by a regular compass. Some of these trammels can be used with a beam to make up a beam compass.

  • A beam compass is used to scribe circles and the radius length.
  • The circles and radius length can be changed by moving the trammel either towards the center of the beam or towards the outer end of the beam.
  • Trammel heads can also be used to bisect lines and angles.
  • This tool has a pointed end that can usually be replaced with a pen, pencil, crayon, or soap stick in order to mark different materials.
