## How To Use A Combination Square

A combination square has many different uses. Learn how to make 45-degree or right angle cuts. It's easy to use for any DIY project.

Today, I'm going to show you how to use a combination square. A combination square is in inches, well, this particular one is in inches and centimeters. Okay.

Ranging from 10 centimeters up to 30 centimeters, and inches, 1 inch upto 12 inches, this combination square has a tightening knot on it and an untightening knot. And the way it works you can slide the ruler up and down and then you tighten the knot and that stops the ruler from moving up and down. Okay.

Now, this is a right angle here. Okay. So, what we can do is depending on the measurement that we're given, so, for demonstration purposes lets say 30 millimeters.

I unscrew the knot and I move the ruler down to the 30 mark and I tighten the knot like so. From this flat point here to the top of the rule is 30 millimeters exactly. Okay.

So, for instance, if I needed to mark this piece of wood I needed to, say I needed to come within the piece of wood 30 millimeters,okay, I would set my combination square to 30 millimeters, 3 centimeters. I place the combination square on the piece of wood like so and I can mark from that, from that point to that point is 3 centimeters to 30 millimeters. Another thing we can do with a combination square is it gives us a perfect 45 degree angle.

So, for instance, if I wanted to cut this at 45 degrees I can place the combination square up against the piece of wood like so. As you can see, that's giving me a 45 degree angle. Score the line or score the ruler with a pencil which will give me that 45 millimeter line which we can cut to.

Also, this particular combination square which is quite unique, so, for instance, if we're using this for metal work we can use, set the combination square to the correct dimension and we can score using the little scriber. Score the level. On this, we're using wood, but if it was metal, and also, on this you've got a level here.

Okay. So that can give us, it gives us metal. The great thing about them is that when you set the design measurement, it stays.

And that is how we use a combination square. I hope you found today helpful on the different techniques and methods on using certain tools on different DIY projects. If you would like more information, please visit my website. .
