Here is my latest ball machine, TurnPike. It has one track measuring over 32 feet, and features lots of winding, looping, banked-turn goodness that takes a single ball over 20 seconds to navigate (plus the lift). You will notice that it is very similar to my previous ball machine, "Loopy". However, apart from being much larger, TurnPike also has extra supports added, a new way of banking the turns and a slightly different lift, that allows the roller-coaster tubing to go up the lift and join the tubing at the top, making a continuous loop.
Step 1: Preliminary Notes...
Before we start, there are a few things I need to warn you of that will be coming up in the forthcoming steps.
#1, I label my photo numbers, and give specific instructions for each photo. It is very important. Also, if I label multiple photos, say example photos 12-15, it means that photos 12 through 15 are all following the same command, so if I say "Photo #2-4: Build part A" It means that photos 2, 3, and 4 are all different photos of one piece you should build, so don't build the same piece thrice.
#2, This instructable is divvied up into smaller parts that connect onto larger parts. Now, this ball machine is built on a Blue rod X Blue rod frame, and there are cross supports made up of an orange connector with two white rods on each end, being skewered in the middle by a yellow rod. This forms an X shaped support, as seen in photo #2 of this step. This will come up everywhere in this instructable. Now, if part A has just a yellow rod at one end, and it connects to part B, which has an orange-and-white assembey, there is a good chance that when they are connected that the yellow rod will go through the hole in the orange connector. See for example, photos 3-5.
Photo 3: Not that this piece has an orange connector with white rods sticking off the end there. First you will build this piece (not now, it comes up in step 12...)
Photo 4: Next you will build this part, which has a yellow rod sticking out.
Photo 5: Now the pieces from photos 2 and 3 are connected, and the orange connector with the white rods has a yellow rod going through it.
This kind connection also happens all over the place in this instructable, so be wary.
#3 Sort of an add-on to my last point... Concerning the yellow rod/orange-connector-and-white-rod cross supports... They are everywhere, and very often, not all of the four points will end up connecting to a connector. See for example photo #6. One end of that yellow rod isn't connected to anything, and that will often be the case, though it might be the orange connector/white rods that aren't connected.
#4 Lastly (and least important...), you may not be able to see them all, but on every tracking piece, there are four dark grey connectors. See Photo #7. Also, the dark grey connectors also point in the direction that the ball will roll over said tracking piece.
I think that's just about it! If you're all ready lets dive into this project!
Step 2: Piece List
This is whopper of a piece list. I've tried my very best in making accurate counts, but on a project this size, there are bound to be counting errors. Please forgive me. I think, however, that my counts wont be off than about 5% of the total number of any given piece.
Best of luck to you!

All ready! GO!
Step 3: The Lift
This is the aforementioned lift. For some strange reason this pretty basic lift took 54 photos to make instructions of.
At least its thorough.
1-3: The chain. There are 52 links in it, with a red connector on every 3rd link. The way it works out, there should be one spot with a gap of four chain links between connectors. Also, make sure that the connectors are facing the right way on the chain.
4-6: Build this long chunky thing.
7: Make these two panel things. Remember the grey spacers, and note that the heads of them are different to each other.
8-9: Make these three gear assemblies. They are all identical.

14-15: Now put your two main pieces together like so.
16-19: Connect the whole dang thing! It should be pretty straightforward.
Step 20: Track Piece #17
One more attempt at a joke.
What makes the Titanic and the Toronto Maple Leafs so similar?
1-3: Build this big 'ol panel.
4-6: Build its counterpart.
7-9: Connect the two.
10-11: Build this dropping track piece. You should be able to build this one without much instruction by now.

6-7: Connect the two panels.
8-9: Build these two parts.
10-11: Build this bent thing.
12-13: Connect the bent thing to the two parts made in photos 8-9.
14-15: Now add the bent part to the tall chunk you made at the start of this step.
16: Make this tracking piece.
17: Build these two as well.
18-19: Put the tracking pieces in on top.
20-23: Attach to the main machine! All connections should be straightforward.
Step 22: Track Piece #19
Another nice and simple step.
1: Build these three pieces, they are all identical.
2: Build this little piece.
3: Connect it like so to one of the pieces made in photo 1.
4: Make this similar bit.
5: Connect it to the part made in photo 3.

16-17: Add the tracking pieces in on top.
18-20: Add it on the bottom of your machine.
Step 23: Track Piece #20
An even shorter step. Go!
1: Build this panel.
2: This one too.
3-4: Connect the two.
5: Make this little stubby part.
6: Build this little one too.
7: Combine the two little parts.
8-9: Now add the part made in photos 5-7 with the ones made in 1-4.
10: Make this tracking piece.
11: Build this longer track piece.
12: Put those two tracking pieces in on top.
13-15: Add it on to the main machine.

This is a long, funky step. Sorry about that.
1: Make this piece.
2-3: Make this odd bit.
4-5: Make this similar odd bit.
6: Combine the odd bits.
7: Now add on that part from photo 1. Put this chunk aside for a moment.

15: Put them in on top.
16: Build this incredible little part.
17: Connect it onto the blue rods of the tracking piece as shown.
18-19: Grab that chunk you made in photos 1-7 and connect it to the piece you made in photos 8-17. Now put this larger piece aside for a moment. This is where things begin to get really weird.
20-21: Build this bendy bit.
22-23: Now make this other part.
24: Combine the parts in photos 20-23.
25: Make this little guy.
26-27: Add it onto the part you just made.
28: Make another little tracking piece.
29: Add it on on top like so.
30-32: Now add it onto the end of the part made in photos 20-29.
33-36: Now take the larger piece you put aside in photo 19, and add it onto what you just made. It should now look like this.
37-41: Add it in on top of the whole machine! There are numerous connection points here, be sure to get them all!
Wohoo! One more to go!
Step 25: Track Piece #22
1-2: Build this tracking piece. If you need more photos refer to step 7, its identical to the track piece in there.
3: Make side panels.
4-5: Add the two panels onto the sides of the track piece.
6: Build these two parts.
7-9: Now make this bendy bit.
10-11: Attach the two parts from photo 6 to the bendy bit.
12: Now attach the tracking piece to the part you just made.
13: Build this two tracking pieces.
14: Add them in on top.
15-16: Build this tracking piece that has some other stuff attached.
17: Add it onto the end of the chunk that you've made.
18-24: Slap it in on top of the main machine.
Step 26: Adding the Tubing
Here we go!
You'll need two lengths of rollercoaster tubing of at least 32½ feet. The two lengths can be made up of smaller pieces spliced together if need be.
1: Start on the lift. It's the best place to splice two pieces of tubing together. I did it about halfway up, but it doesn't matter very much where exactly you start.
Step 27: Modifications
After I took my ball machine apart and put it all back together for the instructions, I made a few mods to my machine that may make yours work better. They are optional, though if any balls are falling off the track, you should probably make these modifications.
1-3: This is on the second level from the top. I bumped up the outer side, as the ball was sliding around more than I liked.
4: This was just a mistake I made in the instructions. There was a blue rod coming down from where the yellow connector is now. It obstructs the path of the ball, so it obviously has to go.
5: Here I dropped the first blue rod length section of the track after the turn. It stops the ball from bobbling around as it heads into the next turn.
6: Move over the blue rod in the box here. The ball sometimes clips it on the way by otherwise.
7: Not so much a mod as a reminder to pull of the railings as high as they will go. It helps the lift work properly.
8: This is thoroughly optional. As you might have noticed, the red connectors on the lift chain come very close to the floor. If you are running your ball machine on a low carpet or hard floor, it wont be a problem, but when it is run on a big fluffy carpet, the red rods can sometimes snag a bit. To fix this, just put a little strip of scotch tape where the red connectors hit the ground to keep things running smoothly.
Thats it! If you have any other mods, please tell me and post pictures! If I think they are good mods I will add them to this page.
Step 28: Add on Some Spindley Legs?
This was just a weird afterthought. The idea was just to get the machine off the ground so that it would be easier to see... These legs put it at about waist height. Its a pretty cool idea, but if you want to try it, don't use the design I used, it sucks.
This is also cool because you can lie down under the ball machine and watch it from there. Its pretty sweet.
Be sure to post photos if you design some legs yourself!
Step 29: Finished!
Congratulations! If you made it this far, you probably have built the machine, so great work, and THANK YOU! Its an honor to have people build my creations, and I get a kick out of it every time.
If you have built this ball machine, I want to know! Also, if you do complete it, post a photo of it and I will upload it to this page.
If you have any comments, questions or whatever, please drop me a line!
