Make a Multi Bit Wood Drill with your bare hands!

Drilling wood, specially if you have to do it by hand, must be done in steps: first small, then a bit larger, then to size. Or as many in-between steps as needed. Woodworkers have such collections of drills, but what about when you have to start from scratch? We start with a bit a good quality steel, that is within easy reach for many people: a bicycle spoke! This series instructions show how to make with your bare hands from a bicycle spoke a multi bit wood drill.

Any hammer is ok. Instead of a sharpening stone, you can grind the spoke on the cement floor or on a stone from the river.

You can do it with your bare hands, a hammer, a stone or a file, a knife or scissers as tools. As materials you need a bicycle spoke and a strip of rubber from a car inner tyre.
