Marble Run V.2

**Coaster105** · #1 11-11-2009, 08:27 PM

Ok. So i decided to make a second Marble ball run.

Using a similar idea from my last one, I made a conveyor belt to lift the marbles up.

It works very well, and never gets stuck.

Comments please!

Wow, great work! Can't wait to see the finished machine

This looks very promising.
The conveyor belt works perfect! I wonder how you connect the motor to it. Is it with gears like normal chain?

^I just used the same small tires that I used the whole way up. It was enough to grip it.

I'm thinking of making it taller, because I started to make some tracks yesterday, but its hardly high enough to do anything.

I will probably raise it another foot ( 2 red rods)

looks realy cool, i don't get how you make it bend upwards (the white rods are used at top and bottom row)

and i think that if you don't have enough grip when making it taller, a white connector with green rods on it could replace the wheel with tyres to get the chain up

stay in touch!

^The white/gray/black rods on the bottom, aren't connected in, their just pushed up against the 3d connectors socket. Its a really gradual radii system.

Its now a foot taller. I couldn't make it any taller, because i was running low on gray connectors for the belt and wheels. I started the first track as well. Pics later tonight.

ok, nice trick, i didn't notice it at first. But as you mentioned it, I can see it now.

I raised it up a foot, and i finished the first track.

I added 3 small xylophone keys, to make it sound a bit.

Pics and vid.

realy cool, something i couldn't be building (I always want to build too big).
keep it up

Lol I like the >ting tang tong< Nice paths, they look great! You could maybe extend the second yellow path. Because it looks like the marble has enough speed to go up a little longer.

You sir are now officially my favorite builder that is not coaster related.

I love how you took a little toy instrument and took it apart for the sound.

Well its Finished.

Second track:

The loop works very well. I've only ever seen 2 or 3 marbles fall off, and when they do they land on the track below it.

Final video

I wasn't exactly pleased with the result at the top. i tried so many different type of track switchers, but none of them were reliable. So instead, i had to make it choose by chance. It seems to go to the left track more often, sometimes not

Nice job. Pretty cool little model.

**Kairah** · #14 11-19-2009, 03:10 AM

Yeah very cool, well done!
