Picture of knex custom coaster car for mini track
 most of the explaining is done in the pictures, but i'll explain it here also. this car was made as proof that the new knex train track can be fitted with a car made of knex itself.

quick alternative (if you have seen actual rollercoasters then you will know what I speak of) if you put the tracks side by side in a manner where you can run wheels next to each other, and another on the underside you can use this for a more stable rollercoaster design, though bigger and less piece efficient.

in the pictures of the custom roller coaster car on the track, ias the car upside down, or right side up? If it is upside down, then I bet that i can make it able to carry a ball as a ball lift for a ball machine just like the big roller coaster cars.

Also, have you found a way for the chain lift to work? I may have an idea.
i think i found a way to mod this car to work on a chain lift.. it worked on mine but its a weird design all you need is one of those green transition connectors from big ball madness (whatever its caled) and a tiny black rod

wow, that's pretty good
thank you
GeekBeam (author)  dltrene4 years ago
but i do find a problem with that design, the car cannot twist, and many regular coasters have pretty tight twists in them
Very innovative. Are you gonna start building coasters.

nope i have not found a way for the chain to work with it, 
second, i haven't determined which side is upwards or downwards
1st: With the picture of the car on the track, you should make the side facing up be the bottom. That way it would be easier to modify it to be able to carry a ball as a ball lift.

2nd: For the chain lift, you should build the chain ABOVE the track so it does NOT run on the actual roller coaster pathing. Then, on some of the chain links, connect a rod so that when the roller coaster car is in place, it will come around and push the car up.

3rd:  l like your new avatar.

 oh and, you like my avatar? awsome.
GeekBeam (author)  zchan11204 years ago
 thank you,
first things first, i think the car being on the upper side of the track is a bad idea...just tried it out in my mind this morning, it won't run very well on banked turns with a ball in place if i do that.

second, the chain lift idea of having it being pushed up should be relocated to pushing against the wheels so they don't get in the way of the actual track

Nice. I may have found analternative to roller coaster tubing (for the big coaster cars) I was going to post it today, but I am not allowed to use my k'nex for a while.

 i think i know what ur sain there (sorry fr th' improvizashun, im kinda mentally in a state u' blarg/ very litle sleep 'n th' pas' fu' days) just leev all the tubin off and replace the orang haf conectrs wif reglar yelows.
Yup. I have found the alternative, using the yellow half moon connectors with little green rods in between. I even found a way to connect it to other pieces to stand it up without interfering with the rollercoaster car. I'm not sure yet, but I might have even found aa way for the chain lift to run.
