By the way what I show you here are not exact instructions, they are more like ideas you could use in your ball machine. But i don't mind if you copy them.
ps im sorry for my bad english, im from holland
here is a link to trainmans instructable, it might be handy to use them both:
and a link to POWER TOWER, my latest ball machine
Step 1: Normal Pathing
this is the most used path, its not very special but it will do.
Step 2: Triangle Path
if its not clear enough please ask a question
the big avantage about this path is that it is very strong and durable, u could make a long piece of it without support.
Step 3: Path DUH
Step 4: Crosties Path
turns might be possible but i think it 'll cost a lot of pieces.
Step 5: King's Path
Step 6: Skinny Path
that thing on the side of the path ( i dont know how to call that in english) ensures that the ball doesn't fly off, u could make it on both sides
Step 7: Rattle Path
the ball has gotta keep his speed on this path otherwise it will stop.
In the second picture there is an alternative but i prefer the first one because it's less likely the ball will stop.
turns are possible but you've gotta use yellow rods instead of red rods, in that case you can connect the path to a classic spiral stair, which is shown in: the ultimate guide of ball machine elements. but if you do so, you could better use the path in the second picture.
Step 8: The Bowl
1: uses many pieces
2: works good when build correctly
3: turns possible
4: ball can reach high speed when you build a long one, in that case i would advice to build a thinner bowl or it costs many many pieces. and when you wanna reach high speed, you shouldn't build turns of course.
Step 9: Jungle Bridge
it isn't really usefull but it looks funny, i would advice to use red rods instead of yellow, it works better and it looks better. except i didn't have enough because im building a rollercoaster that took em all.
Step 10: The Snail Shell
the snail shell ( its called that way because when you make this element bigger you've gotta shape it like a snail shell.):
this element is an example of an element with 2 balls needed.
when you dont make this element exactly correct, it wont work
this element works as explained in the picture, follow the correct order of the notes starting with number one.
Step 11: Well... the Uh Thing?
everybody knows this but nobody posted it as an element, (although it is seen in some ball machines on instructables.). for people who dont know how it works, look in the picture.
Step 12: The Dumper
if you wanna know how to build this here is a link:
whew that is a lot of text.
Step 13: Double Drop
its very simple, when the first ball drops in nothing happens, but when a second ball comes in they both drop down. it's very usefull if you wanna build a yin yan track.
Step 14: Halfpipe
it uses no orange tubing connectors because i dont have them, if you do have them, i would advice to use those, it works better. well, at least it does when you actually put tubing on them.
Step 15: Rollerbal Lift
the rollercoaster cart takes the ball up and releases by turning the track upside down while still going straight forward.( i dont know how to say that more charming ): and back at the lift both tracks fuse back together again.
of course, you gotta make the rollercoaster lift a lot bigger than this because otherwise it wont work, this is just an example.
here is a link for a video featuring a rollerball track:
and here is my own ball machine with a rollerball lift: POWER TOWER
