Introduction: Knex RUBBER BAND Motor And/or Knex Gun

This is my FIRST instructable so plz don't be too harsh.


Before I start, please note that this DOES need improvement, and I meen it really does. But it works, so... yeah...

Also, you may have noticed it can also be a rubber band gun (title).. well to do that you just leave the blue piece off and do NOT cut the rubber band. You would turn it about 0.5 turns and release. The wheel will spin and launch the rubber band.




WHAT YOU NEED:
1 large yellow gear.

1 orange straight connector

5 Yellow (or grey) 5-way connectors

1 purple connector

1 blue connector (the purple connector and the blue connector should be able to attach without other pieces, but do NOT attach them yet... ;)

3 red (or tan) rods.

2 Yellow rods.

2 blue rods.

1 red (or grey) 3-way connector

2 tan clips.

1 rubber band (cut)

Step 1: Build It.

The intro should explain it. It is very simple. The next step is a video on HOW to USE it.

Step 2: HOW TO USE IT! (video)


If that did NOT work, then here is a link.

Enjoy. Please comment on the motor and post any improvements.
Also, please remember this is my first instructable, so please tell me how to improve it.

Thank you for taking the time to at least check this out. Have fun!

Can you use a small wheel

This "thing" looks like it needed updated even from 2 years ago...

this would be great for a roller coaster boost

How to put this nicely... you desprately need better directions, and the parts you listed did not match up to your pictures at all. please re-do thhis because i really want to build it, thanks.

why don't u use a gray connector attached directly to the rod and just loose the gear

can you replace something for the big yellow gear? If not where can I get them?

A different type of gear is all I could think of.

I made myself something like that in the past ,but when I put on more than 6 rubber bands the whole structure broke. At least this RBG gun you made works better than mine. Good gun. Note: I found that yours broke under 10 rubber bands.
