How about a shot from the side ?

awesomeman108 (author)2011-06-17

this is the ''BEST'' pointless ball machine ''EVER''.

TheKnexDude (author)2011-01-26

it has one element, witch is the track

imans314 (author)2010-06-08

just made it. I love it though it is useless.

nye99 (author)imans3142010-06-15

took the words strait off of my keyboard

colton blake (author)2010-06-02

This thing was amazing, yet so simple.

andy410 (author)2010-05-02

Where do you get the red gears?

Bartboy (author)2008-09-28

My motor dose not work, it is the one like yours, but older.

Mudbud (author)Bartboy2010-01-25

were do you get motors like that!!!!!!!!!!11?!?!?

Bartboy (author)Mudbud2010-01-27

In the old sets, when they came out.

dsman195276 (author)Bartboy2008-09-28

on this the speed of the motor is critical to making it work(less speed = less kick to the ball making it launch forward). try changing the batteries in it.

Bartboy (author)dsman1952762008-09-28

okay, but I did have to rewire and re solder it, as the wires broke, so ill try that

lilnorm123 (author)2009-05-24

can u make this with only four big gears? i dont have 6.

AngelCutums (author)lilnorm1232009-05-24

You should try taking out the two outside(the ones in between the top and bottom) gears. I haven't made it myself, but it looks like it would still work. (P.S. you would also have to take out some of the chainlinks)

lilnorm123 (author)AngelCutums2009-07-21

thanks!!!

iasinme (author)2009-07-19

hey, i tried to make this and it just doesn't have enough information.

mettaurlover (author)2008-12-07

you call THISpointless?!?

you have not even heard of POINTLESS until you have seen my parent's efforts to clean my room!

smattman22 (author)mettaurlover2009-07-14

haha ditto :P

mettaurlover (author)smattman222009-07-15

seriously: it makes the average landfill look clean.

smattman22 (author)mettaurlover2009-07-15

well i picked mine up so i could play with knex :D

mettaurlover (author)smattman222009-07-17

don't worry; my floor is juuusssttt clean enough to use as a workspace.

DJ Radio (author)2008-10-05

LOL @ 2 things 1. your name-"alex Jolly"???? 2. that is the worlds most silly ball machine ever

jollex (author)DJ Radio2008-10-05

What's wrong with my name?

DJ Radio (author)jollex2008-10-05

nothing, just sounds funny. do you live in the US?

jollex (author)DJ Radio2008-10-05

I used to.

DJ Radio (author)jollex2008-10-05

would this knex set have enough connectors?

http://knex.com/Thrill_Rides/motorized-madness-ball-machine.php

lilnorm123 (author)DJ Radio2009-05-24

im not sure about connectors but it only has 4 gears. _

jollex (author)DJ Radio2008-10-06

To build this? If yes, then probably.

DJ Radio (author)jollex2008-10-06

not that, i mean a knex gun

jollex (author)DJ Radio2008-10-06

No, it has lots of blue connectors but not enough other kinds. I recommend using eBay.

AngelCutums (author)2009-04-12

I just finally finished my own "mini ball machine." (my first ball machine 2!). It is actually slightly shorter than yours. Yours is 9 to 91/2 inches tall, mine is about 8 1/2" .It's almost exactly the same length but it has a larger width. ( I did not use micro-knex). Question: I'm new to instructables and have never posted one. Do I have to actually post the instructions or can I just put up a video, like you did for Project S?

hockys1 (author)2009-04-06

it works though i just built it

PieMaster777 (author)2009-03-07

it is not pointless its mindless lol

ajleece (author)2009-01-17

very cool!!

cstrike pwner (author)2008-10-21

5 stars! BTW I modified it so it has a longer track, but still doesn't take many pieces. I can put a picture up if you want.

jollex (author)cstrike pwner2008-10-21

Thanks, and I would love to see a picture.

cstrike pwner (author)jollex2008-10-22

This is it

I'll post if wanted.

anaconda (author)cstrike pwner2008-10-22

post!

cstrike pwner (author)anaconda2008-10-24

That will work, expect it in at least 3 days.

anaconda (author)cstrike pwner2008-10-24

yay!

cstrike pwner (author)anaconda2008-10-28

Yes, yay. It may be longer i don't want to mae instructions now.

well that's good; it looks pretty cool

I broke it to make ( do you know the hand held cannon? looks like a crossbow. ) a smaller version of the hand held cannon.

I remember that one

That is a Horrible horrible picture.

cstrike pwner (author)anaconda2008-11-02

I may not post it i am making a sniper rifle and may need the parts.

anaconda (author)2008-10-19

5 stars! it's good for people who don't have enough pieces to build big ones (not me! i have enough pieces) :D

dance1212 (author)2008-10-13
