This the picture of the upper part of my loop.
The whole loop will be shown tomorrow.
Do you think it have sharp spots?

This loop will be used for my next coaster.

UPPER PART OF THE LOOP:

I think that it looks good so far. But, I will have to see the loop tomorrow.

[HamenChiz]

Thanks. I really like to join your company.

BECAUSE

I BUILD SMALL COASTERS!!!

Do you think i should support it more

[SuperTKDKid]

your loop is really good, but you should add on to your supports by making them a box, which will then help your loop be stronger.

[TheSUCKCrew]

Those supports look horribly weak.
You have to do what ^ said, because you will loose all your speed this way.

[SuperTKDKid]

exactly, shaking, at least in my opinion, takes away from a coaster, unless it looks cool.

Once you finish the loop it will look really weird because you will have a twist where the train reaches vertical. For bigger loops, that is no big deal at all. But with a small loop, that twist because very shape due to the lack of space for that twist to happen.

Your solution here is to make a nonstandard connection. For the pull in and pull out, make your standard center of the grid connections up to about 45 degrees, and have the top of your loop at the very center of the element (as you have it). After that 45* mark though, your loop should start making its lateral change. The verical support should just be a cross tie with a single connector through a granite rod (held in place with spacers or connectors). That way you won't get a sharp twist in the loop.

Here is the finished loop.
I've fixed everything from supports to the track.
and its smooth.





I know that there is something wrong in the track at the 1st picture.

[~stεεlspectrum~]

Good, you followed PKI's advice; now all you need to do is adjust the track a bit. Take a look at the first picture - on the right side. See how the track curves out to the right? Just adjust the cross-ties around the curve to get rid of it.

[HamenChiz]

I've fixed everything.

Do you think it is not sharp for a 3 car train?

Will the back of the 1st car hit the front of the 2nd one?

And i built a heartline roll.

Pics will be posted tomorrow.

Because i reviewed for a quiz.

[dk36870]

Very nice, like the way it looks like an actual style loop.

Hope you finish what your working on


*Good Luck*:dwnk

[steve461]

hey guys, some great advice here. I'll be attempting my first loop today as i made a start on a roller coaster yesterday. Will also start a new thread as im sure i'll need some knexpert advice

[HamenChiz]

This is my heartline thingy.

[Jonny]

I like it but, you mine as well have just made this your construction thread.

[TheSUCKCrew]

^Agree.
Looks good.
Supporting could be better though.
