How to Build an Archimedes Screw

Step 10: Housing the Motor

We had to find a way of holding the motor safely above the screw and it also had to be held in such a way that it couldn't rotate.  To house the motor we used the casing from the cheap drill as it was already the correct size so fitted perfectly over the motor and chuck.  We cut the drill handle off and sanded down the rough edges to get the right shape.

We decided, as we are Team Shark, as a bit of fun, to make the motor housing look like a shark so we first spray painted the casing white and then shaded a blue grey colour over the top.  We added an MDF fin and voila - shark.  As I said, this is just a bit of fun and it passed the time while we were waiting to get things done in the workshop.

The motor is stopped from rotating as it is screwed to the back plate of the holder and the holder will be securely attached to the frame.
