Introduction: Tectonic, Knex Ball Machine

This is my first (working) ball machine, and it took me about 2 weeks. I want to thank all of the people who came up with the great ideas for the elements. The videos not great, but you don't need to tell me, and this is my first instructable, so be nice!

Good job! I just started too, like literally.

I wish I could make something like that.

Good job, looks like you're kind of in the same boat as me just starting out.

For your first instructable, this is pretty great! The ball machine you built is awesome. Next time you make a ball machine, build bigger!

lopertt (author)2012-03-07

Uh, this probably only took about 750-1000 pieces to build. Plus, he said it only took him 2 weeks to build. Wrong Instructable?

This is great! But I guess you don't have cats?! Mine would have it torn down and me sobbing in about ten minutes! Great work though!

Jago97 (author)2010-12-02

if you don't mind me asking, how long did it take to build, collect all the stuff and where on arth did you get it all from? How much did this all cost?

ericthered98 (author)Jago972010-12-02

I had bought various sets, and for my birthday my aunt got 20 lbs. of knex from ebay. It took me about 2 weeks to build.

bosniaguy (author)ericthered982011-02-23

I do my knex shopping at Knexusergroup because there is loads of cool stuff on there!

Jago97 (author)ericthered982010-12-03

20lbs!!!! God how much did that cost?

Purple Waffles (author)Jago972010-12-04

If you think that is a lot, type Cataclysm ball machine in the search bar.

If you think this is cool go to your search bar and type paper marble run its almost the same but made out of paper and is a marble run

Jago97 (author)Purple Waffles2010-12-05

yeh i saw it a while ago. Absolutely massive i know.

ericthered98 (author)Jago972010-12-03

I don't know, but it was probably a lot!

bosniaguy (author)2011-02-22

Obviously you have the motorized madness ball machine set from K' you can tell by the green track and the black and white balls

Foxtrot70 (author)2010-11-25

WOW!!! This reminds me of the "Mouse Trap" game I had as a kid. Excellent work!!!

ericthered98 (author)Foxtrot702011-02-14

I love that game! :P

cfcubed (author)2011-01-27

Not bad! Much better than my first attempt lol. Just a little suggestion: Next time make it a little shorter, but denser with elements. This is just my opinion of course. Great job overall though.
