I created my first simple stool with maximum rigidity and the most simple construction in mind, but a few members of my family prove that it still could topple if you stand on the absolute edge. So I enhanced the design with tilted feet so the base is greater that the top board, loosing a little rigidity in the construction. Still this version is able to support a jumping dad, so everything's fine.
Like the last time I used a 4 mm single flute endmill, cutting through 18 mm pine with 9 mm depth per cut at 2800 mm/min. I didn't need tabs as the compressed sawdust is able to hold the pieces in place. I glued the supports to the step board on the whole to enshure maximum stability. The handheld router helped with a nice round over and mineral oil finished the surface.
