Introduction: K'NEX Rail Car and Track

Another cool and somewhat pointless K'NEX item made by me. this one has a car that gets pulled up and down a track by a chain that circles the track.

it's a pretty simple design, and easy to make (though if you make the track long like mine it can use up a good amount of pieces).

mine is 4 FT. 3 in., but it could be made lots longer.

it is made up of a two long lines of yellow connectors connected with green rods. it has supports every 4 yellow connectors. and front of it has two sets of gears(one hooked up to a motor) that the chain is looped around to send it in the other direction. the back is a almost exact copy of the front. the gears are in the same place, just there is no motor.

well, i hope you like it!

a very similar one is posted here:

Step 1: Car

that care is really nothing new or great. it's just a simple car with no treds on the wheels. the wheels fit perfectly on the track, the "curve" on the wheel rims make it so the car can not slide off of the track.

the top has a rod and connector that hooks up to the chain. it is made so it can turn and move in all directions so it can move when it reaches the turns on the ends of the tracks.

i used a black gray rod in this because it would not work well with a bent rod. black rods are more straight then regular grey rods because they are more resistant to bending.

the pictures are pretty self explanitory.

Step 2: Front Track and Chain Guide

well, the most complicated part is adding the motor. this part is pretty basic.

the chain goes around the read gears.

the random connectors on the red rod are just "filler connectors" as in there just there to take the place of spacers and make sure the rod does not slip out.

Step 3: Back Track and Chain Guide.

basically the same at the front, just with no motor.

Step 4: Track Pieces

make as many as you want. i used 6 but you can use as many as you want.

Step 5: Chain and Finishing Up

the chain is 116 links long for my version, but this will change depending on how long your track is.

now, putting on the chain and connecting the track is all self explanitory so i won't go into that.

to add the car just put it on the track and connect the red connector to the chain.

now turn on the motor and watch the car go back and forth. :-)

just some info the reason they are stronger is because they are made of carbon rather than plastic

(You got this idea from a place called scotts design gallery, right? The place where I found the soma cubes?)

Yeah he did.

well, i must admit that they are very similar, but upon closer inspection you can see that there are many differences. now, the front and back are very close(i can't tell for sure, since he only has one view of the back and two views of the front.) there is also no supports under the track, and it bends down. though they have the same design, they are different, just the mech is the same.

The cars are exactly the same apart from the arm that connects to the chain.
His does have supports, although it does bend because the supports in the middle are shorter than the ones at the edges.
The front is exactly the same ('cept for the part under the gears where you have your grey rods inline and he doesn't).
Your back is a little bit different because you modified it to use a different motor.

Even with the slight differences you claim to have, this would still only counts as a slight modification and a reference to the original design should still be made.
I have a knex computer on KI that I built after I was inspired by one I found on the internet. After I made one using a similar mech, and I had severely reduced the size by completely redesigning it (one can no longer recognize it as a modification of the original) I still gave credit to the original. You only slightly modified it (it is still recognizable) and you didn't even give Scott a single link.

Negative twelve internets to you!

i told you, i never saw that before. all i did was make the car as simple as i could(which i can see he also did). the original car i was going to post it with was different. i just thought this up, and some how he had the same idea. but i will post a link just to stop you from complaining.

Denying plagiarism only makes you look like a fool.

author
dsman195276 (author)oodalumps2008-10-11

look, i did not plagiarize this. i thought it up my self. if you don't believe me fine, but i did think this up.

author
oodalumps (author)dsman1952762008-10-11

It's the same exact thing as Scott's design. You've now lost the little respect I had for you.

author
dsman195276 (author)oodalumps2008-10-12

it is not the same thing and i thought it up. i know i'm right, and i don't need to explain it to you. and really, by the way you act and all, i don't care if you have respect for me or not.

he also has the big motor that plugs into the wall.

I should modify this to work as a ball tower lift as it would work brilliantly

i'm making a special one with my crossbow pistol thing as a weapon on top, combined with an auto-firing system that i made for it:) the gun, with one rubberband, put a half centimeter deep hole in my concrete wall!

p p p p p p p p p p POST!!!!!!!!!!!!!!!!!!!

no. i'm not going to post that, for many perfectly sane reasons.

yet anohter form of transportation...i dont have enough chain links for the distance i need, so for now ill try to stay with the sky tram...wait a ho...if i could get string to stay on the gears and have friction, i could use this method still right?

author
Jesus. (author)arrow shot2009-05-14

way to ho???

hemmmmm whyat about putting the chain under the car

author

How'd you get it to turn then? Not that this can, but i'm sure you could

author

I CAN MAKE IT TRUN BUT I DONT HAVE THE KNEX

author
jedff (author)2008-12-29

made it its pretty good

author
the_burrito_master (author)2008-09-22

nice very good! this is sweet!... yet pointless unless you put a plate on top of it to the it to the dish washer.

author

yeah when i saw it i imagined it set up between two doors down my hallway. and instead of a straight track with yellow connectors, why dont you use rollercoaster tubing then have turns and stuff that then travel all around your house. OMG I NEED SOME CHAIN LINKS AND SOME ROLLERCOASTER TUBING

author
grevious (author)grevious2008-12-08

ok i have chain links... yet no tubing. and im 2 gears short =_=

author

lol

dsman195276 (author)grevious2008-09-23

originally the car was made for that, the only problem is that you can't have the car connection stay on the inside for the inside turn, and there is one in every turn, unless you made a circle.

author
DrWeird117 (author)dsman1952762008-10-27

THAT IS SO COOL! I made a bigger one, and I give my cat rides.

author
grevious (author)dsman1952762008-09-23

uhhhhhhh....... what? lol maybe you mean it can only make left turns? well if you have a house like mine were the hallways connects to the kitchen then the kitchen to the loungeroom then the loungerrom back to the hallway, then it would be possible, but i think im getting at what you mean :P

Haha, funny! I like it! 5.0 and fav.

This is so cool, dang me for not having enough chain links to make one worth making! (If I made one the car would probably move about 6 inches each way...)

author

Ha!!! I don't believe it, I have been making one of these too with the same track as well(although mine is a robot train)!

author

But I didn't have a cool reverse like you!

author

the reverse was kinda a unexpected effect. i wanted to make the chain pull the car, and i know i would need to loop the chain. then i just figured out that all i needed to do was make the car hookup make the turn at the ends.

author
Vynash (author)2008-09-22

nice job dsman195276 this is so cool 5*s and fav (like usual)

kl, this could be used in a roller coaster as a lift! =D
