Trammel head body

A beam is held against the body of the trammel head and secured in place when the adjustable nut is tightened. The capacity of a trammel head is the maximum width a beam can have if it is to be used with the tool. This dimension is equivalent to the height of the body of the tool.

Adjustable trammel head nut

The adjustable nut of each trammel head is turned to clamp it to a beam of any length. When this is done, a beam compass is created. The adjustable nut of each trammel head is turned to clamp it to a beam of any length. When this is done, a beam compass is created.

Sharp trammel head point

The sharpened point acts as a scriber when the trammel heads are used to scribe lines or arcs. The point of one or both trammel heads can be removed and replaced with a pencil. When circles are drawn, the point anchors one end of the beam to the surface whilst the other trammel head is pivoted around this point.

Eventually the points of your trammel head will become dull and will need to be resharpened or replaced. Most points can be resharpened but it is also possible to purchase replacement steel points for certain trammels. If replacement points are available, this will be specified in the product information provided with your tool.

Clamping trammel head nut

At least one trammel head in each pair has a clamping nut. When the nut is loosened, the metal point can be removed and replaced with a pencil or a sharp blade. It is then tightened to secure the drawing or cutting tool in place.
