You don't need many tools to make this, I would suggest that most people will have the majority of tools required-here is what you mainly need:
Good selection of screwdrivers-philips and standard.
Hacksaw
Ordinary wood saw
Fretsaw
Jigsaw-(very handy for large cuts & circles for base)
Hammer
Tape measure
Selection of spanners & pliers
Electric drill
Hole saw cutters to fit electric drill
Basically thats it!
