Where do you get the red gears?

Bartboy6 years ago

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

Mudbud Bartboy5 years ago

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

Bartboy Mudbud5 years ago

In the old sets, when they came out.

dsman195276 Bartboy6 years ago

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 dsman1952766 years ago

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

lilnorm1235 years ago

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

AngelCutums lilnorm1235 years ago

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 AngelCutums5 years ago

thanks!!!

iasinme5 years ago

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

mettaurlover6 years ago

mettaurlover mettaurlover6 years ago

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

smattman22 mettaurlover5 years ago

haha ditto :P

mettaurlover smattman225 years ago

seriously: it makes the average landfill look clean.

smattman22 mettaurlover5 years ago

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

mettaurlover smattman225 years ago

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

jollex (author) DJ Radio6 years ago

What's wrong with my name?

DJ Radio jollex6 years ago

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

jollex (author) DJ Radio6 years ago

I used to.

DJ Radio jollex6 years ago

would this knex set have enough connectors?

lilnorm123 DJ Radio5 years ago

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

jollex (author) DJ Radio6 years ago

To build this? If yes, then probably.

DJ Radio jollex6 years ago

not that, i mean a knex gun

jollex (author) DJ Radio6 years ago

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

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?
