I needed to unscrew a metal plate on the old sewing machine to clean under it, but the handles of the regular screwdrivers were too long to fit. So I made a small wooden handle for a screwdriver bit. I used a hole saw with my drill press to cut a circle from a scrap of oak flooring. At the same time, it drilled the hole in the middle to be the right size for a very tight fit for the screwdriver bit. Then I sanded the edges and forced the bit into the hole.
