Opus1 Caliper Attachment © Patent Pending
I use a set of electronic calipers to measure my cane. I have made a little attachment that connects to one of the arms of the caliper. This attachment has a small pin that becomes the contact point for measuring the gouge dimension. It is EXTREMELY accurate and easy to read. Using this setup is very convenient. You can even ZERO the calipers at any point if you would like to find the difference in measurement between two points. The attachment can be removed by turning a single screw so the calipers can be used for general measuring. The units can be in either English or Metric units.
The best feature is that it is no compensation for the "mechanical advantage" you have with the screw thread of a conventional micrometer. It is very easy to measure soft cane as too thin and hard cane as too thick. With the caliper, the action is a sliding motion with the thumb. You can feel the exact contact point with the cane whether it is soft or hard. This gives you a more consistent measure of your gouge dimension. The attachment's contact point is very small so you can easily see where you are measuring.
|The Calipers that I use are not very expensive when compared
to many of the dial indicators and micrometers that are on the market.
