This tip video was created by Jodee from Inspire Woodcraft. It focuses on a common frustration among woodworkers—owning a marking gauge but rarely using it because it doesn’t perform well out of the box.
The core issue, Jodee explains, isn’t the tool itself but the condition of the cutting wheel. With a bit of sharpening and better technique, your marking gauge can become a go-to tool for clean, accurate layout work.

Why Marking Gauges Often Get Ignored
Marking gauges are built to scribe precise layout lines parallel to an edge. They’re critical for joinery and layout but often get pushed aside in favor of pencils or other tools.
The most common reason? The cutting wheel is dull or improperly shaped. Instead of cutting into the wood, it skates across the surface, making rough or inaccurate marks and leading users to give up on the tool entirely.
How to Test if Yours Is the Problem
Jodee offers a simple test: try slicing a piece of paper using only the weight of the marking gauge and the sharpness of the wheel. If the paper doesn’t cut cleanly, your wheel is too dull.
This method quickly reveals whether the tool needs sharpening without needing any special gauges or alignment jigs.
Sharpening the Cutting Wheel
The real breakthrough comes from sharpening the wheel correctly. Jodee removes the cutter from the gauge and uses the “Scary Sharp” method—flat abrasive sheets on glass or a known-flat surface—to tune the wheel.
Light, circular movements on the abrasive surface ensure even wear. The goal is to polish and refine the edge while preserving the wheel’s shape.
During this process, rotating the cutter every so often helps avoid uneven grinding. High and low spots, invisible to the eye, can be identified by checking the wheel’s flatness against a stone or metal plate.
Once a burr forms on the beveled edge, Jodee lightly removes it using the edge of the stone. This is a key step that restores the cutting surface without dulling the freshly sharpened edge.
Does Grit Level Matter?
While you can go up to extremely fine grits (8,000–60,000), Jodee says that for a marking gauge, a sharp and reasonably smooth edge is more important than a mirror finish.
Once the initial sharpening is done, occasional touch-ups are all that’s needed to keep the wheel performing like new. This means better cuts and less frustration every time you mark a board.
Technique Makes All the Difference
Once the cutter is sharp, how you use the gauge becomes the next factor. Jodee offers a few essential tips to improve accuracy and safety:
- Keep the stock tight against your reference edge. This keeps the gauge aligned properly.
- Pull the gauge lightly toward you. The sharp wheel should do the work without heavy pressure.
- Make several light passes. Trying to scribe too deeply in one cut often leads to slipping or misalignment.
- Watch your hand position. Keep it clear of the gauge’s path to avoid interfering with the tool’s motion.
These habits reduce errors, extend the life of the wheel, and lead to cleaner, more consistent marks—especially important when laying out precise joinery.
How to Handle Difficult Grain
Marking with the grain can be tricky, especially with softwoods. The cutter may catch and create chatter instead of a clean line.
Jodee suggests using short, repeated strokes to work through the grain without tearing fibers. This gives the cutter time to slice rather than skip or dig in unpredictably.
Tips for Mortise Gauges
For woodworkers using a dual-wheel mortise gauge, Jodee recommends focusing on one cutter at a time. Trying to mark with both cutters simultaneously often results in uneven or wobbly lines.
By setting and using one cutter cleanly, you get better results—especially on detailed joinery like mortise and tenon layouts.
Don’t Blame the Price Tag
One of the most helpful takeaways from the video is this: an expensive marking gauge won’t work well if the cutter is dull. And a cheap one can work beautifully if it’s sharpened correctly.
The steel’s quality affects how long the cutter holds an edge, but almost any wheel-style gauge can be tuned to perform at a high level. Sharpness and technique always beat price or brand when it comes to layout tools.
Ongoing Maintenance and Use
Jodee encourages regular light honing after the first sharpening. This keeps the cutter ready without needing a full resharpening each time.
He also reminds viewers that everyone develops their own style. With some experimentation—adjusting grip, pass length, and pressure—you’ll find what works best in your own workflow.
A well-tuned marking gauge also improves the accuracy of every tool that follows. Clean layout lines mean better saw cuts, tighter joints, and less guesswork throughout your project.
Final Thoughts
If your marking gauge is sitting unused in a drawer, now’s the time to bring it back into your shop routine. Jodee shows that with just a bit of sharpening and some simple technique changes, the tool becomes precise, reliable, and enjoyable to use.
Marking layout lines doesn’t have to be frustrating or inaccurate. A tuned marking gauge adds consistency to your projects, reduces layout errors, and helps you build with greater confidence.
