What is a trammel tool?

Trammel heads are marking out tools primarily used to draw large circles or arcs. They are sometimes called trammel points, or trammels. Together with a beam, usually made from wood or metal, trammel heads make up a beam compass. They are clamped a set distance apart onto the beam.

Trammel heads are used in layout work to scribe circles and arcs that are too large to be drawn with a divider or compass. Trammel heads can also be used to bisect lines and angles. They can be used as an alternative to both a marking gauge and a mortise gauge to draw lines a set distance from an edge.
