Project Ideas and Help / Re: Building a Message Mover

You could build a rollercoaster track from one room to the other and attach the message to the rollercoasters?

You could build a ball track and put the message inside the ball?

Can you be more specific? What do you need help with?

Can you share the instructions here?

Edit: I took a couple pictures of my lift and uploaded them here: https://www.instructables.com/id/Knex-Tubeless-Helix-Lift/

Is this the video you're talking about? I've made a lift very similar to this and I could make instructions.



It's nice to see new people joining!

I made a pullback Ferris wheel in one of my ball machines. https://youtu.be/pPgEdyqYFFY?t=1m13s

I'm at the point where I just number my projects. I can never think of a good name.

Have you ever bought knex on ebay and got a weird, torn, plastic bag filled with unusual wheels and other knex pieces which are the wrong colour and don't quite clip nicely to the rest of your knex? You'd find a red flexi-rod in those bags.

I like it, but the squeaking is so annoying.

My plane would probably crash every time it tries to land.

The ball lands on an arm. The counterweight of the arm contains a gear which can move.

Go to 1:36 on this video, it explains one way of achieving your aim.

This machine has been dismantled, but I used the same mechanism in my current machine so if you want I will take detailed pictures of it.

Why do you have two yellow gears? Is it for strength?

The dual alternating axles might not be what you need for this machine. If I understand correctly, the motor only turns the machine in one direction, but when the motor is not connected then the machine can reset. If that is the case, check out the lift in this ball machine:


Can you show us a picture of the machine from a different angle?

I'd like to see that! Can you give a link for instructions/videos?

Project Ideas and Help / [Request] Trebuchet
« on: December 18, 2017, 03:09:46 am »
I've been working on a mechanism that engages/disengages a motor, and I realised that I could use it to reset a trebuchet.
A trebuchet could be used to throw a ball with the use of a heavy counterweight.
Does anyone have instructions for a trebuchet that can be used for a lift (or element) of a ball machine?
