Great job on the box and thanks for the info hairy, I've always wanted to be able to thread things. I've read online that using the hand tools to thread was very difficult and only worked with certain hardwoods. That made me give up on trying. I resorted to making boxes with glass jars inside so I could have screw on tops.
Any chance you might do a blog on how it's done and share a few tricks of the trade. Maybe throw a camera in the background while you work.
