My friend Kiko Denzer dropped off a project yesterday; he wants me to make an adapter to allow the use of 1/4″ hex screwdriver bits in his bit brace. While I enjoy odd projects, I decided to search the Internet and see if anyone already made such an adapter. I discovered two sources, one in Europe and the other more useful source, Lee Valley. They sell bit brace adapters for 1/4″ hex bits as well as 3/8″ square drive sockets at a low price of $8.50 each. Chuck here at TM has already covered actual square taper shank screwdriver bits for the bit brace as well, although the price is significantly greater than the Lee Valley adapters.
This leads me to ask — does anyone know other sources of bit brace adapters and chucks that allow their use with modern straight shank drills and hex bits?
I have a Goodell type keyless 3-jaw drill chuck that has a tapered bit brace shank, but I doubt that they’re made anymore. Of course there are plenty of modern bit braces that have a 3-jaw chuck, but my luddite friend likes using his old Stanley brace, and I don’t blame him one bit.
