I made this screwdriver a few weeks ago, and it has since become one of my handiest tools. I am sometimes away from the shop at different locations building or repairing this or that, and having this tool means I can skip bringing a whole set of screwdrivers. I usually bring a cordless drill and a case of driver bits and drill bits. Now, I just throw this in my tool bag and I’m set. I use it to start small pilot holes, sometimes as a countersink or reamer, as either a long cabinet style or short Phillips or slotted screwdriver, even sometimes chuck up a nail and use as a scratch awl in a pinch. It has turned out to be a very useful tool. (I know, they already have screwdrivers with changeable bits, but for some reason, this tool bridged the gap between drill and hand screwdriver – at least for me.)

I had a spare 3/8” Jacobs chuck laying around, I turned a handle for it out of Zebrawood, gave it a few coats of oil, and it was ready to go.

As far as attaching the chuck to the handle – most chucks are tapped with threads on the bottom. All I did was find a long bolt of the same thread, and cut off the bolt head. Then I threaded the bolt into the chuck, and marked a line when it was all the way in. Then I ground off the threads that I didn’t need and gave the bolt shaft a kind of octagonal shape (with sharp flat sides to prevent turning in the handle) by grinding. Then, I drilled a slightly undersized hole into my handle, threaded the top of the bolt shaft into the chuck, put glue (Gorilla glue, actually – since it expands/foams so well to fill in the voids) all over the bottom of the ground-off bolt shaft, and pressed it into the handle with a vise. It is very strong and I don’t foresee any problems with the handle turning/slipping under even extreme use.

Tremendous idea, at my earliest opportunity I’ll start one, I already have the chuck. Now if only you could incorporate a ratchet.

Thanks guys, like I said – it has become one of my handiest tools.

@jackass – I added a bit about how I attached the chuck to the handle, in case you’re interested. Pretty simple concept with the threaded bolt.

Now I know why I kept all of those old chucks…super idea. I have already seen one where a guy used an old jig saw holder to hold his blades with a similar handle.

I have read that the simplest ideas are usually the greatest ideas. Well you have certainly proven this to be true. I love the design of your handle and your idea. Thanks for sharing it. Now i need to find a spare chuck.
