What are trammel heads used for?
|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.
|Like dividers, when used with a beam, trammel heads are an effective transfer measuring tool.
The trammel points are positioned on either side of an object or set distance. The distance between the trammel points is then checked against a measuring device like a ruler.
