It's a beautiful day at our L.A. office and I'm working on putting up a bunch of new teardrop stock we just received from our wood carvers. I saw a few blogs and instructables on how to measure teardrop plugs, but some tactics are not completely accurate. Many people simply say, take the measurements of the height and the width and divide by two. That method to me is very general and calculations can be skewed depending on the shape.
When we carve teardrops, I prefer the string length method. It is a lengthier process to find the exact circumference of an object, but I think it is worth it.
Let's cut to the chase and see how it's done. I will work in mm instead of metric to be more accurate.
Follow these 5 steps ton how to measure teardrop plugs
1. Take a piece of string about 2 inches long. Measure the middle (wearing surface) NOT the flares of your teardrop plugs.
2. Indicate the starting point and ending point of how much string you used to go fully go around the middle of the plugs. Mark it with a marker or chalk.
3. Flatten out your string on the table and measure it with a ruler or caliper. Again, in millimeters.
4. Take that number and divide it by pi (3.14159265359).
5. The end number is your gauge size.
Here is an example.
Let's say I want to create a pair of 5/8" teardrops. Which is 16mm
I would need my final string length to be 50.2654824574.
Hope that helps!
