Make a step stool / toolbox
This step stool we designed is also a toolbox. More than that, it's sturdy enough to support a big guy or gal.
While your ordinary step stools offer little in the way of support for bigger guys and gals, we designed our step stool to easily hold weight. We also added a storage compartment for tools or supplies.
Made using pine that you can buy at any Builders Warehouse, the step stool doesn't require any specialist tools or fancy angles. The basic design is an easy project even for a beginner.
