You do not need to support both ends of a screw that short.
The reason for supporting both ends of a longer screw are twofold.
-When driving a load, the screw is acting as a beam in compression, and wants to buckle.
-When driving at high speed the screw wants to whip, and bend.
Neither are going to be an issue on your little machine.
Please post photo's as you go.
