Select cog30 and cog10 and Parent [p] to gear01 (Fig.21).

The first gear is complete!

## Revision

Before you start creating the other gears, it is a good idea to revise the relationship between the cogs. Here are the four prototype cogs you created earlier (Fig.22).

Fig. 22

The image below contains three simple gear setups. Consider the following very carefully (Fig.23):

(a) cog40 is rotating four times slower than cog10
(a) cog10 is rotating four times faster than cog40
(b) cog10 is rotating three times faster than cog30
(b) cog30 is rotating three times slower than cog10
(c) cog20 is rotating two times faster than cog40
(c) cog40 is rotating two times slower than cog20

## Creating the Gear System

Following the method outlined previously, create the remaining four gears ([B] - [E]), and rename them "gear02" to "gear05". The aim is to rotate gear01 [A], which will cause the door [F] to move up and down.

Move [w] the gears into a suitable starting position, so that the cogs interlock with each other. You'll also need to individually rotate [e] cogs to achieve this. Do not rotate the spindle/parent objects (gear01 - gear05), only the cogs (Fig.24).

Fig. 24

Note: Take note that gear05 [E] only has one cog: cog30.

## Creating the Door

I added the door to this tutorial because up to this point it is all pretty easy. So, the aim of the door is to complicate matters slightly and challenge you.

The reason the door is slightly complicated is because it needs teeth to interlock with cogs. The problem is you don't know the actual size of the teeth... yet.

Start by making a polygon cube (Polygons > Create Polygon Primitives > Cube)(Fig.25).
