This is the third addition to the interface tutorials, in this one I will teach you how to make a good gear. Ever want to make a gear for you r interface, but you just cant make the right shape? in this tutorial I will show you how to make a good looking gear, without any pre-made shapes.

First open a new file in Photoshop, make the background black, and on a new layer, make a white rectangle, around the same size as the one below. Size will vary depending on how big you want your gear to be.

Now duplicate your layer with the white rectangle, and on your new layer, rotate your duplicated rectangle so it makes a cross shape. T do with go to edit>transform>rotate Then use your mouse to turn it.

Now duplicate the layer again, and rotate your new rectangle to make the shape below.

Repeat:

Now on a new layer, make a circle by using the circle selection tool, and hold shift while your drag your mouse to keep the circle in a perfect shape. Now fill your selection with white, and place it in the middle of your crossing rectangles.

Now make a new layer, and again, make a perfect circle by holding shift and dragging, but this time make it half as small as the last circle you made, or somewhere around half. Then fill your selection with black, and place it in the middle of your white circle.

Now save you black circle selection by going to select>save selection, and name it whatever you would like. Then merge all of your layers, except your background layer by press control+e. Then load your selection of the black circle, and press delete.

Now you have your gear shape. Now just fill it with a gradient, and add detail until you get something you like.

When you are done, place it inside the interface that you have made in the previous tutorials, or one of your own.
