Precision Woodworking Pocket Rules: Anodized Slide Stop Layout Trio
- Laser-etched imperial and metric scales with zero glare on anodized aluminum
- Machined brass thumb-nut slide stop locks rock-solid without marring the rule edge
- Integrated end-rule vertical scale for setting router bit and table saw blade heights
- Compact 6-inch rule fits perfectly into a shop apron pencil pocket
- Square reference face on the stop allows instant, accurate parallel scribing
- Aluminum construction will flex under heavy bending force compared to hardened spring steel
- Anodized edges can nick if dropped directly onto concrete floors
- Slide stop screws must be tightened firmly to prevent shift during aggressive scribing
Repeatable Joinery Layout in Your Apron Pocket
In fine cabinetmaking, measuring with a standard tape measure introduces parallax error and sloppy hook slop. Laying out repeated tenon shoulders, drawer slide reveals, or hinge mortises demands a rigid metal rule with a positive mechanical stop.
This 3-piece precision pocket rule set includes 6-inch, 8-inch, and 12-inch rules, each equipped with an anodized aluminum slide stop locked via a knurled brass thumb screw.
Setting Blade and Router Bit Heights
Beyond marking layout lines on board faces, the tip of each rule features an end-face vertical scale. You lock the slide stop at your target dado depth (for example, 3/8-inch), place the stop flat on your router table insert plate, and crank the router lift until the carbide bit tip kisses the bottom of the rule. It eliminates test cut guesswork in seconds.
Repeatable Parallel Scribing
To scribe a 1-1/2-inch offset along a 6-foot face frame stile, slide the stop to 1.50 inches, snug the brass knob, press the stop against the board's edge, place your 0.5mm mechanical pencil into the rule's graduation groove, and pull both down the length of the timber. Every mark is dead-on uniform.
