Accurate Setting-Out Without Relying on the Walls

The same blue trammel bar used by MyScribe in its flooring setting-out videos.

The MyScribe Trammel Bar makes the traditional trammel method simpler, faster and easier to repeat. Its fixed PIVOT, CIRCLE and ARC positions remove the need to measure or adjust traditional trammel points, helping floor layers create accurate working lines without relying on walls being straight or square.

Ideal for setting out herringbone, basket weave and other patterned flooring, the bar uses simple geometry to establish a true perpendicular line and provide an accurate foundation for the rest of the installation.

Key features

  • Fixed PIVOT, CIRCLE and ARC positions

  • No measuring or adjustable trammel points required

  • Helps establish accurate square and perpendicular working lines

  • Ideal for herringbone and other patterned flooring installations

  • Three clearly labelled 3mm holes

  • Designed to accept the 2.8mm lead used in many mechanical pencils

  • The pivot can also be anchored using a suitable nail, nail punch, scribing pen or similar tool

  • Lightweight blue Perspex construction

  • MyScribe branded and designed for professional floor layers

How It Works

Mark your centre point and anchor the bar through the PIVOT hole. Use the CIRCLE hole to draw the initial circle across your primary working line.

Move the pivot to each point where the circle crosses the primary line, then use the ARC hole to draw matching intersecting arcs. Joining these intersections creates a true perpendicular line through the original centre point, giving you accurate 90-degree working lines.

The same geometric method can then be used to divide those 90-degree sections and establish accurate 45-degree working lines. These diagonal lines provide the correct foundation for setting out herringbone and other patterned flooring installations.

Because the layout is created using fixed geometry, it doesn’t depend on the surrounding walls being straight, parallel or square.

Watch the MyScribe Trammel Bar turn a traditional flooring setting-out method into a simple, repeatable process.

Rather than relying on walls that may not be straight or square, the bar uses fixed geometry to create accurate working lines from your chosen centre point. The clearly labelled PIVOT, CIRCLE and ARC holes remove the need to measure or continually adjust traditional trammel points.

In these videos, you’ll see how the initial circle and intersecting arcs are used to establish a true perpendicular line. The same geometry is then used to create accurate 45-degree working lines, which are essential when setting out a herringbone pattern.

What you’ll see

  • How to position and anchor the PIVOT

  • Drawing the initial circle

  • Creating matching intersecting arcs

  • Establishing true 90-degree working lines

  • Creating accurate 45-degree setting-out lines

Simple tools, proven geometry and accurate working lines—without depending on the walls or shape of the room.
