My new favourite man tool (previous one was the butane powered soldering iron/torch as described in this post) is this Bosch multi-tool. It grinds, sands, saws, makes plunge cuts and it great for tight spots. This tool was essential in cutting off the plastic bits on that step above.
We needed to screw down a piece of wood to raise it so the plastic step fit snugly.
Snug as a bug in a rug.
The finished product. Note the new carpet lining the right side.
