A miter saw

A miter saw is a wonderful piece of machinery. The ability it has to cut wood at any angle is a boon to do-it-yourselfers when fitting a piece of molding into a tight corner or creating an angled brace. But perhaps something is hindering your ability to cut--leaving the saw's gauge with a limited range of motion. Learn how to get around the problem and cut an obtuse angle.


Step 1

Set your miter saw to cut at an acute angle and it will cut at an obtuse angle by default.

Step 2

Determine which acute angle complements the obtuse angle.

Step 3

Imagine cutting an obtuse angle of 120 degrees as an example.


Step 4

Note that miter saw gauges don't go to 60.


Step 5

Set your saw at 30 (90 - 30 = 60) to cut at a 60-degree angle.


Don't bang the saw down onto whatever you are cutting. Doing so could damage the blade. Move it smoothly and steadily to make a clean cut.


Make sure you are wearing goggles or some other eye protection when using power tools. Always keep your fingers clear of the blade when it is moving.
