Which instrument is used for making large circles on drawings or workpieces when a standard compass is inadequate?

Explanation:
Drawing very large circles requires a tool with a long reach beyond what a normal compass can provide. The trammel compass uses a long beam with adjustable guides, letting you set and maintain a large radius while the pencil traces a precise circle. This makes it ideal for arcs on big drawings or workpieces where a standard compass would be insufficient. The other tools aren’t for tracing circles: a regular compass is too short, a dowel drilling jig guides drilling, and a corner clamp just holds pieces at right angles.
