The Impossible Screw will drive you nuts.

Welcome to my impossible screw.

It's a small project you can do in your home shop even if you don't have a milling machine or lathe. A hacksaw and a file will do.

It also makes a nice last minute present.

If you try this I recommend to try it first with a brass screw.
It's very important to deburr it carefully.
Otherwise it will be locked in both directions.

If you give this away I recommend to loctite a small second nut on so that the big nut cannot be moved away from the split point. It will drive anyone nuts who doesn't know the secret.

As a German, I find this acceptably hilarious within the standards of German Humour Directive 10794.456.9783. Now that we have all had a good laugh, it is time to return to work.

I tried to make one, but I had trouble threading my carrot.

[jamesrawlings]

Using the carrot to show how to make this was a perfect teaching method. Thanks for including the explanations.

My great great grandfather once told me that he witnessed the titanic. He said that he advised everyone that the ship was going to sink. Everyone looked at him angry and in disbelieve. He continued to warn people in many occasions until they kicked his ass out of the theater.

I looked everywhere, and nobody sells threaded carrots.

A pirate walks into a bar with a steering wheel extending out of his pants. Bartender: "That has got to be uncomfortable." Pirate: "It drives me nuts!"

I was afraid you wouldn’t reveal the trick.

You know what they say....
Screw till you nut and if you can bolt, you nailed it.

I knew the screw had to be in two pieces but imagined some additional locking mechanism in the middle between the two ends, never thought it was a simple grind & cut away, very clever, I wonder if there can be some application for it in the industry or maybe children toys or something.

This is very cool! I’m gonna make one tomorrow for my kid. He does magic performances and he would get a kick out of this prop. Thanks!! Very well-presented, by the way.

Did you guys noticed "will drive you nuts" like he is talking about screws and stuff
this is *realy clever*

[arponto]

Thanks. I made this, this weekend using a larger brass bolt and nut it's a lot of fun. To keep people from finding out the secret of how it works I put a drop of super glue on the bolt above and below the nut preventing the nut from being removed

[colemanadamson]

This guy has too much enthusiasm in his voice. (Reminds me of the very stern and stoic Germans I actually know personally.)

Using the carrot to demonstrate has got to be the best thing i've seen on Youtube latley.

[TechGorilla]

When you presented the vegetable, I could clearly see the answer. Carrots ARE good for your eyes like mumma said!

That's really cool. Also thanks for showing how. I will build one now.

[hasanmediterraneo]

I made several of the last night to give as gifts, I did drill and tap a 4-40 hole and put a stop screw on both ends to prevent the nut from being unscrewed thus revealing how it works
