This delectable Jacobs chuck key holder was designed along with my mini lathe chuck key holder. Wow talk about a mouthful. That's a lot of chucks and keys.
Like the mini lathe chuck key this was designed to use Kreg screws to attach to the wall. Use them or any screw that has a flat space on the back of the head to keep from splitting the part. You can see the Kreg screw in one of the photos.
Try it, you will like it. You know peer pressure and all of that nonsense.
In all seriousness I hope it works for you. If you like it post a make. If you don't like it post a comment and tell me why. Feel free to post a comment even if you do like it.
