FAQs

Is the Faithfull Jenny Caliper suitable for measuring dimensions?

No, this tool is designed primarily for layout and scribing center lines, not for measuring precise thicknesses or diameters.

Can this be used on materials other than steel?

Yes, it can be used on aluminum, brass, or wood, provided the material surface is firm enough to be scribed.

How do I sharpen the scribe point?

Use a small, fine-grit honing stone or file to carefully maintain the original taper of the point.

What is the maximum capacity of this caliper?

The tool has a 150mm (6-inch) capacity.

Does it require special maintenance?

Regularly wiping it down to remove metal dust and applying a light machine oil to moving parts will prevent rust and keep it operating smoothly.

Troubleshooting

Marks are inconsistent or faint

Check if the scribe point has become dull and carefully sharpen it using a fine file or oil stone.

Tool slides or slips during use

Ensure the locating lug is pressed firmly against the edge of the workpiece and verify that the locking nut is tightened securely.

Inaccurate center location

Verify the leg tension is adjusted properly and ensure the straight leg remains perfectly vertical against the workpiece edge.

Pros and Cons

Pros

  • Durable construction suitable for daily workshop use
  • Effective design for locating centers on round stock
  • Stable operation provided by the integrated locating lug
  • Compact and lightweight for easy transport in a tool belt

Cons

  • Not intended for high-precision dimensional measurement
  • Requires manual adjustment and physical calibration
  • Point may require periodic sharpening for continued accuracy

Setup, Compatibility & Care

To set up the caliper, loosen the locking mechanism to adjust the point to your desired width based on the material radius. Ensure the locating lug is flush against your reference edge before scribing. Regarding compatibility, this tool works best on clean, mill-scale-free steel surfaces for maximum scribe visibility. To maintain the tool, keep the pivot point clean of metal debris, lightly oil the sliding components to prevent corrosion, and store it in a dry tool box or rack to protect the sharp scribe tip from damage.
