Picture of Cataclysm Knex Ball Machine
After over a year of construction, Cataclysm is finally finished! It has 6 paths and 10 lifts. 8 of those lifts are new. It stands almost 8 feet high. I haven't counted the pieces yet, but I will soon. The 10 lifts are organized into 3 networks, each network having two paths. I had to buy many pieces while building, most of which were blue connectors, blue rods, and green rods. I completely ran out of yellow rods. A Lego train runs around the bottom of the ball machine. :-)

This used 16 AA and 3 C batteries to power the motors.

Construction was started on May 25, 2009, and I finished on September 25, 2010.

The grand total of pieces is 28,538!

How much K'nex do you have? And how did you get it all? Buying sets? Ebay? And did you buy them yourself, or did someone else buy them?

I have 40-50,000 pieces, and most were bought from Ebay. Recently I started buying them with my own money, but lots of the other pieces were for birthday/Christmas presents.

have the balls ever hit each other on the race track?!

Shadowman39 (author)  www1391 year ago

No, one ball was always delayed so they wouldn't collide.

WOW!!!!!! that would never work for me!

Nice ball machine! Very innovative and ingenious! :-)

Do you have any idea where I can get some closer images or instructions on the element in 2:29 - 2:33 ?
Shadowman39 (author)  hunter9991 year ago
Alright, I found lots of pictures of it so I put them in an Ible right here.
Wow! Thanks for these! =D

Shadowman39 (author)  www1392 years ago
Cool! Do you build with someone else? (I noticed you said "we"). To embed the video there's an icon near the right side, and when you click it you can paste the embed code there. 
My brother (Weston) helps me he's a good helper!!

i have the same exact lego train w/a lot of extra tracks. I'm thinking of making an NXT train soon, since I have mindstorms NXT 2.0
Shadowman39 (author)  jmiester4 years ago
I think that new light blue train is cool, even thought you have to buy motor and track separately. Do you use 9-volt or RC?
9-volt, with a LOT of tracks including 4 switches and the dual crossover. There's a new one?!?! I haven't been on LEGO.com lately...
Whoops, I meant RC... :-/
Shadowman39 (author)  jmiester4 years ago
The new one is really cool. The 9-Volt system is best, but it's very expensive. Last time I checked on Bricklink straight rails were 20 dollars per piece!
well there not that expensive as far as I know... that might be a freak pricing accident, but its NOT the normal price....
Shadowman39 (author)  jmiester4 years ago
Maybe it was an accident. It was used too. :-P
