Thanks for posting this RWT!!! This will be in my next coaster.

[VV Khan]

I'm glad he brought this back up, more people need to see it.

[JohnMillerFan96]

I tried to build this, but I didn't have ANY of the pieces like half way through. I'm using this so I can build a simpler one for those who only have Screamin' Serpent pieces. This was great! Thanks RWT!

[RightWayTrey]

could you use a chain to get the car through the station?

If you mean to pull the train into the station instead of using a tire drive like I did in the video, then yes, that will work fine. But if the chain pulls the train all the way out of the station without stopping, IMO it defeats the point of the automatic station gates.

Yeah, it does use a lot of pieces that aren't in the SS. That would be great if you could make it with just SS pieces!


I will add on to the tutorial a way to get the train out of the station sometime after I finish the corkscrew. For now I'll tell you a couple ways you can do it and give a pic of how I did it on the Corkscrew.

1. If you're using two trains you can just have one train push the other out.

2. You can add a rotating arm on the station gates which hits an automatic switch (see "Auto on/off Switch" in sig) just before the motor powering the gates shuts off.

Here's a pic:


The piece in the blue circle is turned by the motor that powers the gates. It turns on the red motor in the picture, and the piece in the red circle, which is powered by the motor in the picture, turns the motor off.

If what I wrote is too confusing, All I did was have a rotating arm on the station gates motor turn on an automatic switch. Then just hook up this automatic switch to a chain or tire drive in the station.

And if you still don't get what I'm saying, wait for the tut I'm gonna make.

I think that this is the easiest way of making it automatic. Is just by adding a few gears and a chain you could use a tire drive for this
How it works is by the orange gear that only has teeth on half of it is controlling when the chain moves so when it is not meshing with the other gear the chain doesn’t move but otherwise it dose.

[RightWayTrey]

^ I see a couple problems with that.

1. The orange gear will not turn an exact amount of turns, causing the teeth to always end up in different places. This means the time when the chain moves the train out of the station will always vary.

2. It allows very little time for the train to move into place before the gates open. For those who don't know, for half of the motor's rotation the gates stay shut, this half rotation can be put before or after the gates open and shut. Using your way, the half rotation has to be put after the gates open and shut, which means the gates will immediately start opening after the motor turns on. This means the train will have no time to get into the station before the gates open. The auto gates will still work, the train just won't be there the whole time they're open (which isn't a very long time).

[big builder145]

^yeah i noticed those problems too. It was a quick fix (I came up with it in like an hour) and It isn't very reliable so I wasn't able to use it in my final vid. of Flash. The car just doesn't stop in the same place every time.

[JohnMillerFan96]

Okay, I've made a way to make station gates with pieces from only the Screamin' Serpent set. Note: I used about four screamin serpents and one rippin rocket, but they still have the same pieces, only their color is different.

To start, build this:




Next, you must add grey or yellow rods to all of the 3D connectors exept the one in the picture with half a gray rod, and in the bottom right corner with the metallic green rod.


Add this to the bottom right section of the base.


Place the battery pack in. Note that the round edged motor works but not the square edge. Be sure to add the two black pieces on the side.


Add spacers as shown.




Add two black pieces to the right side of the base.


Build one of these.


Place spacers as shown:


Place on top of base.


Place spacers as shown:


Make this.


Place over battery pack.


Make sure the connector is interlocked with the battery pack switch.


Place motor into green rod.


Make sure the cord is wrapped around this rod shown here:


Next, build this once:


Place into motor and hole in the bottom.


Add this to the bottom right corner on the base.


Construct this in order. Place spacers as shown:














Place as shown. Make sure all loose pieces connect with base.


Add these spacers.


Build this:


And place onto this:


Build this:


And place on to this:


Build this next to where you put the latest construction.


Build this and save it for later.


Now construct this. Place spacers as shown:








Place as shown. Make sure all loose connectors are attached to structure.


Build this:


And connect to these as shown. Also, take the gray rod with black connectors and place it under the rod build erlier in the empty space.


Place spacers as shown:


Add spacers and blue rod and black connectors.


Build this:


Place as shown:


Build this:

Make sure rod is placed correctly:


Place as shown and hold it there.


Make sure gears mesh:




Next, build this:


Place on top of structure:


Add spacers as shown:


Make sure black connector is attached to the gray rod.


Make sure to add connector to the top of the rod.


Add blue rods:




Build this:


Make sure spacers are placed correctly:




Make sure rod is placed correctly:


Place here and make sure the gears mesh:

Make nine of these:


Make sure rod is placed correctly:


Place in both the bottom holes and the second holes in the middle:


It should look like this, and all gears should mesh:


Before placing the floor on, make sure these two gears mesh tightly:


When you place your floor onto the structure, the rods attached to the gears MUST go through open holes like this:

Your floor will be supported by 3D connectors attached to the blue rods.


Now, add gates:




Add track:


To activate the gates, push the lever here towards the motor:


The rod in the motor will shut it off. Be sure the long rod's extension faces to the right of the structure. Push lever once. When it turns off, adjust the gates so they're closed. Turn it on again, and it should give you a quick open-close action. If anyone wants a video, it will take a while to make, but I'll make it! Thanks for viewing!:tmbs

This isn't your thread. Just because it's the same thing does not give you the right to post it here. You need to make your own thread for it.

Also, the way you have you station gates, they won't open. i really hope, for your sake, that that was on purpose. Decent tutorial, I guess, but I'd rather go with the automatic one.

[~stεεlspectrum~]

I agree...I'd rather go with RWT's fully automatic gates, though yours (JohnMillerFan) are fairly nice. On Leviathan though, I'm just using a Lego Mindstorms, which is a lot simpler. But if I didn't have one, I'd go with RWT's.

[RightWayTrey]

Your whole gate opening mechanism is pretty nice. The switch mechanism is not that great. You could probably have the train trigger the switch if you just move that red gear out of the way. Also it's not geared down at all. The gates would barely have 3 seconds to open and shut!

If you could gear down the switch so that it stays on longer and extend the switch so that the train turns it on, this would be a very nice tutorial.

[JohnMillerFan96]

DDRman, this is for people who have only SS sets, RWT has pieces that don't come with the SS. Thanks for telling me where to post, too.

RWT, I could only go for a short open close period because the gears are the same size. I say it's better to build this with your ss sets then to have almost no pieces to build yours. But for people who have enough pieces, DEFINATELY build your gates!

[LaMbChOpZ]

looks like it'll work. idk. gonna try it

[decaxxeca]

I m gon tak lyk dis 2!
GENIUS!!

[TheSUCKCrew]

"I m gon tak lyk dis 2" (I'm gonna say?)
Genius, but 1 year old...

[decaxxeca]

what i had said was i am going to immatate his manner of typing because his typing style is very hard to understand.

[RCT2123]

Really guys? He is new leave him alone. At least he wasn't like Tis is so coo! He has a legitimate comment...

[Maxwell Graham]

I built RWT's Station Gates , But they dont turn off. Why is this?

[RightWayTrey]

Every motor has a switch that behaves a little differently. Just experiment with different lengths for the arm that shuts off the switch. The easiest solution is to cut a piece to the right length. You can also try putting spacers on the rod for the switch.
