Product Information
Full details
The Faithfull Spring Divider 150mm is a professional-grade precision tool ideal for machinists, woodworkers, and metalworkers who require exact measurements and layout marking. Its key strength lies in its balanced design and smooth adjustment mechanism, which allows for repeatable accuracy during intricate scribing tasks. One caveat to keep in mind is that the polished natural steel finish requires regular maintenance to prevent oxidation, especially in humid workshop environments.

FAQs
What is the maximum opening width?
While the tool is classified as 150mm, the effective scribing range is typically just under the nominal length depending on the angle of use.
Are the tips replaceable?
No, the tips are integral to the hardened steel legs and are not designed to be replaced independently.
Can this be used on wood and metal?
Yes, it is designed for marking on both wood and metal surfaces, though the points may require more frequent sharpening if used heavily on hardened steel.
How do I sharpen the points if they dull?
You can touch up the points using a fine-grit diamond sharpening stone or a small oilstone, maintaining the original bevel angle.
Does this tool come with a storage case?
No, it is typically supplied as an individual tool without a dedicated carrying case.
Troubleshooting
Adjustment screw feels stiff or gritty
Clean the threads with a wire brush or solvent, then apply a drop of light machine oil.
Divider legs move too easily
The bow spring may have lost tension; check that the central nut is fully engaged and the bow is not obstructed.
Points are not meeting correctly
Check the hinge pivot point for debris and ensure the legs are not bent; if alignment is off, gently realign the hardened tips.

Setup, Compatibility & Care
To begin using the tool, simply turn the center adjustment nut to expand or contract the legs to your desired measurement. Once set, ensure the points are perpendicular to the surface being marked to achieve the most accurate scribe.
Regarding care, because the tool is made of natural polished steel, it is susceptible to surface corrosion. Always wipe the divider clean with a lint-free cloth after use. We recommend applying a light coating of machine oil or a corrosion inhibitor to the legs and the adjustment threads once a month, especially if the tool is stored in an unheated workshop. Store in a cool, dry place, preferably in a tool roll or drawer organizer to prevent the tips from dulling against other heavy tools.
