Mortice & Marking Gauges – Precision Woodworking Layout Tools

Mortice and marking gauges are essential woodworking hand tools for accurately marking parallel lines and joint dimensions on timber. Used in furniture making, cabinetmaking and traditional joinery, these tools help establish consistent cutting references for mortices, tenons, rebates and other woodworking joints. The range includes traditional marking gauges, wheel gauges, cutting gauges and digital options for precise timber layout.

Woodworking marking gauges use an adjustable fence and marking point to scribe lines at a consistent distance from a timber edge. Traditional pin gauges provide a simple approach to layout work, while wheel marking gauges feature circular cutters that score timber fibres for clean, accurate lines. Selected designs include micro-adjustment mechanisms for fine positioning.

Mortice gauges are specifically designed for marking two parallel lines that define the width of a mortice or tenon. Adjustable cutting points allow woodworkers to match the required joint dimensions, improving consistency when preparing traditional timber joinery. Cutting gauges use sharp blades to score timber fibres, making them particularly useful for marking across the grain.

Available in traditional hardwood and brass designs alongside modern metal and digital configurations, marking gauges offer different approaches to precision woodworking. Features such as locking fences, fine adjustment controls and digital measurement displays help improve repeatability and accuracy. Choosing the right gauge makes measuring and marking timber faster, more consistent and reliable.

FAQs

What are marking gauges used for in woodworking?

Marking gauges scribe accurate lines parallel to a timber edge, providing cutting references for joinery, rebates and other woodworking tasks. Their adjustable fences help maintain consistent marking distances across workpieces.

How does a mortice gauge differ from a marking gauge?

A marking gauge typically scribes one line parallel to an edge, while a mortice gauge uses two adjustable marking points to establish the width of mortices and tenons simultaneously.

Why choose a wheel marking gauge?

Wheel marking gauges use circular cutting blades to score timber fibres, producing fine, accurate layout lines. They're particularly useful for marking across the grain and preparing precision woodworking joints.

Can marking gauges improve joinery accuracy?

Yes. Marking gauges establish consistent reference lines for mortices, tenons, dovetails and rebates. Their adjustable fences help maintain accurate dimensions and reduce measuring errors during woodworking layout.

How do micro-adjustable marking gauges work?

Micro-adjustable marking gauges feature fine adjustment mechanisms that allow precise positioning of the cutting wheel or marking point. This helps woodworkers make small measurement changes without repositioning the entire fence.

Are digital marking gauges useful for woodworking?

Yes. Digital marking gauges provide an electronic measurement display for setting marking distances. They're useful for repeatable layout work, precise adjustments and woodworking applications requiring consistent dimensions.

How do you maintain a woodworking marking gauge?

Keep marking points and cutting wheels sharp, clean adjustment mechanisms and protect metal components from moisture. Regularly check fence alignment and locking mechanisms to maintain accurate, consistent woodworking measurements.
