Ever wondered why your car is making that funny noise? Or why your new TV isn't getting any reception? It could be something as simple as a loose bolt or a faulty wire. And that's where feeler gauges come in.
A feeler gauge is a precision tool used to measure the distance between two surfaces. They're typically made of thin, springy metal blades, each with a different thickness. By inserting the blades into a gap and feeling for the one that just fits, you can determine the gap's exact width.
Feeler gauges are handy for a wide range of tasks, including:
Using a feeler gauge is a relatively simple process. Here's how:
Pro tip: If you're having trouble finding the right fit, try using a thicker blade and gradually working your way down.
There are two main types of feeler gauges:
Blade feeler gauges are more versatile and portable, while dial feeler gauges are more precise.
Feeler gauge sets typically include a range of blade thicknesses, from 0.001 inches to 0.100 inches. This allows you to measure gaps of varying sizes.
The Case of the Missing Spark
A mechanic was called to fix a car that wouldn't start. After checking the battery, the fuel pump, and the spark plugs, he finally realized that the spark plug gap was too wide. The feeler gauge confirmed it, and a quick adjustment fixed the problem.
The Tale of the Tilted TV
A homeowner was struggling to get a clear picture on his new TV. After fiddling with the antenna and cables, he realized that the TV was tilted slightly forward. A feeler gauge showed that the feet were uneven, and a few careful adjustments solved the problem.
The Triumph of the Troublesome Hinge
A carpenter was installing a new door, but the hinge kept getting stuck. After trying everything else, he used a feeler gauge to check the gap between the door and the frame. It turned out to be too tight, and a slight adjustment fixed the issue.
Q: What's the difference between a feeler gauge and a micrometer?
A: A feeler gauge is used to measure the distance between two surfaces, while a micrometer is used to measure the thickness of an object.
Q: Can I use a feeler gauge to measure the depth of a hole?
A: No, a feeler gauge cannot be used to measure the depth of a hole.
Q: How often should I calibrate my feeler gauge set?
A: Feeler gauge sets should be calibrated annually to ensure accuracy.
Q: Where can I buy a feeler gauge set?
A: Feeler gauge sets can be purchased at most hardware stores and automotive supply stores.
Q: What's the most important tip for using a feeler gauge?
A: Be patient and careful. It takes practice to get good at using a feeler gauge.
Q: Can I use a feeler gauge to measure the thickness of my hair?
A: Yes, but it's not recommended. Feeler gauges are designed to measure the distance between two surfaces, not the thickness of an object.
If you're a handyman, a mechanic, or anyone who works with machinery, a feeler gauge is an essential tool to have in your toolbox. It's a simple tool to use, but it can save you a lot of time and frustration by helping you to make precise measurements.
