Fixed circular cutter
A small single-bevel wheel is secured with a center screw. It scores the fibers; no rotating bearing is depicted or assumed.

An original educational poster identifies 7 documented construction features. The numbered descriptions remain readable below the artwork on narrow screens.
- Fixed wheel cutter
Single-bevel cutter scores a fine line; it is not a rolling wheel.
- Cutter screw
Retains the wheel for documented removal and honing.
- Stainless rod
Slides through the body to set distance from the face.
- Brass face
Broad circular face registers against the work edge.
- Anodized body
Houses the sliding rod and its adjustment hardware.
- Lock thumbscrew
Side knob secures the rod after coarse or fine adjustment.
- Micro-adjust collet
Rear knurled hardware advances the rod for fine setting.
Technical references: Veritas 05N3510 official product · Veritas wheel marking gauge instructions. The rod withdraws for coarse setting and the wheel is fixed by a central screw. The cutter scores rather than rolling; the body, face and micro-adjust hardware remain together in this educational arrangement. Original educational artwork depicts documented component groups and their relationships; it is not a service sequence or a replacement for the exact model manual.
02 / Understand the tool
What it is and what each part does
The Veritas 05N3510 micro-adjust gauge has an anodized aluminum body, a broad brass face, a sliding stainless rod and a single-bevel hardened steel wheel cutter fixed at the rod end. Despite the name, this wheel does not roll along the line. It slices a fine score. A pin gauge can work with the grain but may tear across it; the sharp circular edge is useful in both directions when set and guided correctly.
Release the side thumbscrew for a coarse rod setting. The rear collet and knurled micro-adjust hardware advance the rod in small increments, then the side screw locks it. Keep the brass face against one straight reference edge and draw the fixed cutter through a controlled pass. The central cutter screw permits the maker-documented removal for honing; the construction view retains it on the rod.
Stainless rod
The rod slides through the body and sets the cutter's offset from the brass face.
Body and brass face
The broad face bears against the work edge while the body guides the rod and carries the lock.
Coarse lock and fine adjust
The side thumbscrew locks the rod. The rear knurled collet and brass nut provide fine setting after a coarse slide.

02 / Working principle
Set, guide and control the action
These decisions make the mechanism useful at the bench.
Choose the datum
Prepare a straight edge; keep the brass face fully against it throughout the mark.
Set and lock
Slide close to dimension, use the micro adjust for the last correction, then lock the rod without shifting it.
Score lightly
Make a light first pass, then deepen only if needed. Guide with the grain direction and supported fingers.
Joinery shoulders
Scribe a tenon shoulder or rebate line at a repeatable distance from an edge.
Thickness transfer
Use a known board or measured setting to transfer stock thickness to mating components.
Grain-crossing layout
A sharp wheel can cut a cleaner cross-grain line than a blunt pin when pressure is restrained.
03 / At the bench
Setup, technique and finish quality
Use the steps for a first pass, then inspect the work before changing the setup.
- Inspect the wheel edge, center screw, rod lock and brass face before setting the gauge.
- Choose and mark a straight reference edge on all mating pieces.
- Loosen the side lock, slide the rod near the intended offset and use the micro-adjust hardware for the final setting.
- Lock the side thumbscrew; verify the cutter distance on scrap before touching the project.
- Keep the brass face flush to the edge and draw a light first scoring pass.
- Repeat gently for a deeper line, then clean and protect the cutter.
The wheel is fixed
Its circular profile and bevel aid clean scoring; the wheel does not spin as the gauge travels.
Register one face
Use the same reference edge for mating joinery to prevent small stock-width differences from becoming misaligned shoulders.
Pressure can move the line
Pressing hard may pull the face away from the edge or follow grain; a light first pass is more reliable.
What changes by model or material
A plain gauge relies on sliding alone; this reference adds a fine-setting rear collet.
Mortise gauges can mark two parallel lines; the illustrated 05N3510 has one cutter.
Other cutter geometries need different pressure and grain handling.
Choosing the tool
- Select a face broad enough to stay stable on your stock.
- Check rod travel and fine-adjust feel for your typical offsets.
- Confirm replacement wheel and screw availability.
Useful accessories
- Rule for checking offsets
- Small driver for cutter screw
- Fine sharpening stone
Consumables
- Replacement cutter wheel when worn
- Light rust protection for the rod
04 / Keep control
Care, troubleshooting and safety
Secure the work, protect sharp edges and release any stored clamping pressure before adjustment or maintenance.
Care checklist
- Wipe resin and dust from the rod and face.
- Hone or replace the wheel using the maker's directions.
- Keep the center screw secure without overtightening.
- Store the cutter protected from impact.
Common mistakes
- Assuming the wheel rotates and pressing sideways.
- Locking before the fine setting is complete.
- Letting the face lift off the reference edge.
- Attempting a deep score in one pass.
Safety at the operation
- Handle the exposed wheel as a sharp edge.
- Keep the free hand behind the scoring path.
- Secure narrow stock so the gauge cannot tip or slip.
When the result goes wrong
Check the reference edge, face pressure, rod lock and first-pass force.
Inspect the bevel and sharpness; make a lighter pass and check grain direction.
Clean the rod, lock and fine-adjust hardware and retighten as instructed.
