Introduction: Knex Ping Pong Ball Retriever Claw

Picture of Knex Ping Pong Ball Retriever Claw

I built this in my spare time to help my dad who has a bad back. We would play ping pong together and the ball would come off the table, and he would always have to bend down and pick it up. So I invented the ping pong ball retrieval claw.

Step 1: Create the Pole Part

First you need to create the pole part. It is made from 4 grays and 4 purple connectors and 8 white pecies.
How many of these you make will depend on the hight of the person using it.

Step 2: Create End Handle Part

Well this is pretty simple, just create the end handle (as shown in picture).

Step 3: Create the Front Claw Part

Again just make the end claw part.

Step 4: Finally Assemble It All Together

Assemble the end handle part to the pole, and that to the claw.



Step 5: VIDEO!!!

It would be nice if you were to mention KNEX somewhere since that is the product you're using. The title might be a good place. At least it's not a gun.

Very impressive adam! You should make this an Instructable! Not that I'd necessarily look at it since 'Knex' tends to put me off... Now, if you could only create a cooling chamber or install it in the fridge somehow with an extended trigger for front access.

Kiteman (author)2007-02-28

While I certainly don't look at every K'Nex instructable that gets posted, this one caught my eye. Its so nice to see K'Nex being used for things besides weapons - they obviously have a lot of potential, and this looks like a great project. Nice work!

Lostkid (author)2007-02-28

What do you have against knex guns, Las vegas? We are just a bunch of people who test our design skills and have fun by making knex guns.

TeacherOfTheWays (author)2007-02-28

I fixed it.

TeacherOfTheWays (author)2007-02-28

Sorry I kinda forgot to mention that.

Whaleman (author)2007-02-27

Wow, a simple solution to a simple problem, but unfortunately i wont be making it because i dont have a ping pong ball, but my friend does, but when i play with him, the ball always goes over the wall. But great instructable, very simple, very good!
