This 10″ contour gauge makes measuring for detailed or difficult cuts easier.
Having seen ads for these all over Instagram and other websites I was intrigued. For less than $15 I had to give a contour gauge a try. They are as handy, and easy to use, as the videos suggest.
This Avide gauge is cheap and it works. The pins are held into the frame with enough pressure that a very moderate amount of force will shape the gauge, but the pins will not slide or move once you draw it away and go to work.
I am also interested in the 5″ version as there are some tight spaces around a few pipes this one may not fit. We shall see.
