I have to chime in that windshield wiper inserts make excellent wrenches, and they're free if you go to a body shop or some other place where old blades are thrown out. There are a variety of sizes, which is good because there are a variety of keyways they'll need to fit in.
The only other thing you need is a way to cut and bend them: a hacksaw and pliers or a vise.
