That is actually shaped pretty good....

[Maverix]

Why is the lift steeper then the drop?

That is actually shaped pretty good....

It might be shaped well, but it needs to be WAY steeper.

[~G3n3rOo2256~]

changed the tubes to boxes. Pics:

Also, I have a name, shockwave or twister

[DDRman732865]

Both those names have been taken. As for the coaster, the predrop is way to big, it should be less than a gray tall.

[Little Kuriboh]

The pre drop is overkill if it will drop after it moves strait. It would be different to have a pre drop that has to turn be larger than a gray tall if your track connecting skills arent good. I'm not saying anything about anyone. I didnt say anyones skills arent good it was a example...

Pics of the half loop. put a lot of supports in. I think it looks pretty good. Video comng soon. Could a MOD change this thread name to water rush

Not good. Supports on top are warping, shaping is way off. You'll need a bigger pre drop and a more corkscrew shape in the reverse sidewinder.

[DDRman732865]

Besides the horrid shape, you really need to refer to this post.

There seems to be some misunderstanding when members say "support it more" or "attach it to the structure more." More support does not always mean more supports. For example:



Notice how many combinations of pieces he has connecting the crossties and flexis to the main structure.

More examples:

Basically just play around with it until you find a connector/rod combination that works for you.

The best type of connectors for this are:



The blue/black connector that can change its angle. This allows versatility in the way you position it.



The ball and socket connectors add even more versatility.

Here's what NOT to do.

Horrid bumpiness aside, there are no connections between the track and the structure for, like feet. Bad.

TBM's unfinished zero-g is anotehr good example. (the finished product is sexy...) When there are no track connections, the track can flex, causing loss in speed.

Side note: You want connections that won't warp or deform your track. Experiment a little until you find a connection that will work the best. Remember: The more the merrier... *ahem*... better.

Notice how I used your coaster in the 'what not to do' section? Yeah. Keep trying.

[~G3n3rOo2256~]

so I need to make a better corkscrew shape and better shaping for the half loop and more supports?

[DDRman732865]

You don't have to confirm it, just do it.

[~G3n3rOo2256~]

does anyone have a tut of a half loop or any pictures of one made out of knex?

[pkiknex25]

Dude, just build it yourself. Look at pictures of real ones and knex for shaping, but don't go copying off someone elses. Copying gives you nothing but a final product.

[Maverix]

^Exactly, if you can't build without tutorials, you can't build at all.

[DDRman732865]

Here's what you do: You make a prefect quarter circle, then you make another perfect quarter circle a lot bigger than the other one. There, half loops 101 for n00bs.

[~G3n3rOo2256~]

Here is my new half loop. I put some tubing in the middle of the x-ties to make the track sturdier. I compared my half loop to Noxius's half loop and looks the same. Can I move on? Pics:

Could a mod change the thread name to: [SS Looper] Water Rush?

[dylan]

dude nice start to the coaster

[Fraggie]

it is still under-supported, but shaping looks pretty good.

[dylan]

you should definetly support it more

[weeeee78]

There is a banking bump on the third 3-d connector fom the left.
